Index-1 v FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) PREFACE This manual meets the first aid training needs of individual service members. Because medical personnel will not always be readily available, the nonmedical service members must rely heavily on their own skills and knowledge of life-sustaining methods to survive on the integrated battlefield. This publication outlines both self-aid and aid to other service members (buddy aid). More importantly, it emphasizes prompt and effective action in sustaining life and preventing or minimizing further suffering and disability. First aid is the emergency care given to the sick, injured, or wounded before being treated by medical personnel. The term first aid can be defined as “urgent and immediate lifesaving and other measures, which can be performed for casualties by nonmedical personnel when medical personnel are not immediately available.” Nonmedical service members have received basic first aid training and should remain skilled in the correct procedures for giving first aid. This manual is directed to all service members. The procedures discussed apply to all types of casualties and the measures described are for use by both male and female service members. This publication is in consonance with the following North Atlantic Treaty Organization (NATO) International Standardization Agreements (STANAGs) and American, British. Canadian, and Australian Quadripartite Standardization Agreements (QSTAGs).

General When a nonmedical service member comes upon an unconscious or injured service member, he must accurately evaluate the casualty to determine the first aid measures needed to prevent further injury or death. He should seek medical assistance as soon as possible, but he should not interrupt the performance of first aid measures. To interrupt the first aid measures may cause more harm than good to the casualty. Remember that in a chemical environment, the service member should not evaluate the casualty until the casualty has been masked. After performing first aid, the service member must proceed with the evaluation and continue to monitor the casualty for development of conditions which may require the performance of necessary basic lifesaving measures, such as clearing the airway, rescue breathing, preventing shock, and controlling bleeding. He should continue to monitor the casualty until relieved by medical personnel. Service members may have to depend upon their first aid knowledge and skills to save themselves (self-aid) or other service members (buddy aid/ combat lifesaver). They may be able to save a life, prevent permanent disability, or reduce long periods of hospitalization by knowing WHAT to do, WHAT NOT to do, and WHEN to seek medical assistance. NOTE The prevalence of various body armor systems currently fielded to US service members, and those in development for future fielding, may present a temporary obstacle to effective evaluation of an injured service member. You may have to carefully remove the body armor from the injured service member to complete the evaluation or administer first aid. Begin by removing the outer– most hard or soft body armor components (open, unfasten or cut the closures, fasteners, or straps), then remove any successive layers in the same manner. Be sure to follow other notes, cautions and warnings regarding procedures in contaminated situations and when a broken back or neck is suspected. Continue to evaluate. 1-2 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 1-2. Terminology To enhance the understanding of the material contained in this publication, the following terms are used— • Combat lifesaver. This is a US Army program governed by Army Regulation (AR) 350-41. The combat lifesaver is a member of a nonmedical unit selected by the unit commander for additional training beyond basic first aid procedures (referred to as enhanced first aid). A minimum of one individual per squad, crew, team, or equivalent-sized unit should be trained. The primary duty of this individual does not change. The additional duty of combat lifesaver is to provide enhanced first aid for injuries based on his training before the trauma specialist (military occupational specialty [MOS] 91W) arrives. The combat lifesaver’s training is normally provided by medical personnel assigned, attached, or in direct support (DS) of the unit. The senior medical person designated by the commander manages the training program. • Trauma Specialist (US Army) or Hospital Corpsman (HM). A medical specialist trained in emergency medical treatment (EMT) procedures and assigned or attached in support of a combat or combat support unit or marine forces. • Casualty evacuation. Casualty evacuation (CASEVAC) is a term used by nonmedical units to refer to the movement of casualties aboard nonmedical vehicles or aircraft. See also the term transported below. Refer to FM 8-10-6 for additional information. CAUTION Casualties transported in this manner do not receive en route medical care. • Enhanced first aid (US Army). Enhanced first aid is administered by the combat lifesaver. It includes measures, which require an additional level of training above self-aid and buddy aid, such as the initiation of intravenous (IV) fluids. • Medical evacuation. Medical evacuation is the timely, efficient movement of the wounded, injured, or ill service members from the battlefield and other locations to medical treatment facilities (MTFs). Medical personnel provide en route medical care during the evacuation. Once the casualty has entered the medical stream (trauma specialist, hospital corpsman, evacuation 1-3 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) crew, or MTF), the role of first aid in the care of the casualty ceases and the casualty becomes the responsibility of the health service support (HSS) chain. Once he has entered the HSS chain he is referred to as a patient. • First aid measures. Urgent and immediate lifesaving and other measures, which can be performed for casualties (or performed by the casualty himself) by nonmedical personnel when medical personnel are not immediately available. • Medical treatment. Medical treatment is the care and management of wounded, injured, or ill service members by medically trained (MOS-trained) HM, and area of concentration (AOC) personnel. It may include EMT, advanced trauma management (ATM), and resuscitative and surgical intervention. • Medical treatment facility. Any facility established for the purpose of providing medical treatment. This includes battalion aid stations, Level II facilities, dispensaries, clinics, and hospitals. • Self-aid/buddy aid. Each individual service member is trained to be proficient in a variety of specific first aid procedures. This training enables the service member or a buddy to apply immediate first aid measures to alleviate a life-threatening situation. • Transported. A casualty is moved to an MTF in a nonmedical vehicle without en route care provided by a medically-trained service member (such as a Trauma Specialist or HM). First aid measures should be continually performed while the casualty is being transported. If the casualty is acquired by a dedicated medical vehicle with a medically-trained crew, the role of first aid ceases and the casualty becomes the responsibility of the HSS chain, and is then referred to as a patient. This method of transporting a casualty is also referred to as CASEVAC. 1-3. Understanding Vital Body Functions for First Aid In order for the service member to learn to perform first aid procedures, he must have a basic understanding of what the vital body functions are and what the result will be if they are damaged or not functioning. a. Breathing Process. All humans must have oxygen to live. Through the breathing process, the lungs draw oxygen from the air and put it into the blood. The heart pumps the blood through the body to be used by the cells that require a constant supply of oxygen. Some cells are more dependent on a constant supply of oxygen than others. For example, cells of 1-4 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) the brain may die within 4 to 6 minutes without oxygen. Once these cells die, they are lost forever since they do not regenerate. This could result in permanent brain damage, paralysis, or death. b. Respiration. Respiration occurs when a person inhales (oxygen is taken into the body) and then exhales (carbon dioxide [CO2] is expelled from the body). Respiration involves the— • Airway. The airway consists of the nose, mouth, throat, voice box, and windpipe. It is the canal through which air passes to and from the lungs. • Lungs. The lungs are two elastic organs made up of thousands of tiny air spaces and covered by an airtight membrane. The bronchial tree is a part of the lungs. • Rib cage. The rib cage is formed by the muscleconnected ribs, which join the spine in back, and the breastbone in front. The top part of the rib cage is closed by the structure of the neck, and the bottom part is separated from the abdominal cavity by a large dome-shaped muscle called the diaphragm (Figure 1-1). The diaphragm and rib muscles, which are under the control of the respiratory center in the brain, automatically contract and relax. Contraction increases and relaxation decreases the size of the rib cage. When the rib cage increases and then decreases, the air pressure in the lungs is first less and then more than the atmospheric pressure, thus causing the air to rush into and out of the lungs to equalize the pressure. This cycle of inhaling and exhaling is repeated about 12 to 18 times per minute. Figure 1-1. Airway, lungs, and rib cage. 1-5 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) c. Blood Circulation. The heart and the blood vessels (arteries, veins, and capillaries) circulate blood through the body tissues. The heart is divided into two separate halves, each acting as a pump. The left side pumps oxygenated blood (bright red) through the arteries into the capillaries; nutrients and oxygen pass from the blood through the walls of the capillaries into the cells. At the same time waste products and CO2 enter the capillaries. From the capillaries the oxygen poor blood is carried through the veins to the right side of the heart and then into the lungs where it expels the CO2 and picks up oxygen. Blood in the veins is dark red because of its low oxygen content. Blood does not flow through the veins in spurts as it does through the arteries. The entire system of the heart, blood vessels, and lymphatics is called the circulatory system. (1) Heartbeat. The heart functions as a pump to circulate the blood continuously through the blood vessels to all parts of the body. It contracts, forcing the blood from its chambers; then it relaxes, permitting its chambers to refill with blood. The rhythmical cycle of contraction and relaxation is called the heartbeat. The normal heartbeat is from 60 to 80 beats per minute. (2) Pulse. The heartbeat causes a rhythmical expansion and contraction of the arteries as it forces blood through them. This cycle of expansion and contraction can be felt (monitored) at various points in the body and is called the pulse. The common points for checking the pulse are at the— • Side of the neck (carotid). • Groin (femoral). • Wrist (radial). • Ankle (posterior tibial). (a) Carotid pulse. To check the carotid pulse, feel for a pulse on the side of the casualty’s neck closest to you. This is done by placing the tips of your first two fingers beside his Adam’s apple (Figure 1-2). Figure 1-2. Carotid pulse. 1-6 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (b) Femoral pulse. To check the femoral pulse, press the tips of your first two fingers into the middle of the groin (Figure 1-3). Figure 1-3. Femoral pulse. (c) Radial pulse. To check the radial pulse, place your first two fingers on the thumb side of the casualty’s wrist (Figure 1-4). Figure 1-4. Radial pulse. (d) Posterior tibial pulse. To check the posterior tibial pulse, place your first two fingers on the inside of the ankle (Figure 1-5). Figure 1-5. Posterior tibial pulse. 1-7 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE DO NOT use your thumb to check a casualty’s pulse because you may confuse the beat of your pulse with that of the casualty. 1-4. Adverse Conditions a. Lack of Oxygen. Human life cannot exist without a continuous intake of oxygen. Lack of oxygen rapidly leads to death. First aid involves knowing how to open the airway and restore breathing. b. Bleeding. Human life cannot continue without an adequate volume of blood circulating through the body to carry oxygen to the tissues. An important first aid measure is to stop the bleeding to prevent the loss of blood. c. Shock. Shock means there is an inadequate blood flow to the vital tissues and organs. Shock that remains uncorrected may result in death even though the injury or condition causing the shock would not otherwise be fatal. Shock can result from many causes, such as loss of blood, loss of fluid from deep burns, pain, and reaction to the sight of a wound or blood. First aid includes preventing shock, since the casualty’s chances of survival are much greater if he does not develop shock. Refer to paragraphs 2-21 through 2-24 for a further discussion of shock. d. Infection. Recovery from a severe injury or a wound depends largely upon how well the injury or wound was initially protected. Infections result from the multiplication and growth (spread) of harmful microscopic organisms (sometimes referred to as germs). These harmful microscopic organisms are in the air, water, and soil, and on the skin and clothing. Some of these organisms will immediately invade (contaminate) a break in the skin or an open wound. The objective is to keep wounds clean and free of these organisms. A good working knowledge of basic first aid measures also includes knowing how to dress a wound to avoid infection or additional contamination. 1-5. Basics of First Aid Most injured or ill service members are able to return to their units to fight or support primarily because they are given appropriate and timely first aid followed by the best medical care possible. Therefore, all service members must remember the basics. • Check for BREATHING: Lack of oxygen intake (through a compromised airway or inadequate breathing) can lead to brain damage or death in very few minutes. 1-8 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) • Check for BLEEDING: Life cannot continue without an adequate volume of blood to carry oxygen to tissues. • Check for SHOCK: Unless shock is prevented, first aid performed, and medical treatment provided, death may result even though the injury would not otherwise be fatal. 1-6. Evaluating a Casualty a. The time may come when you must instantly apply your knowledge of first aid measures. This could occur during combat operations, in training situations, or while in a nonduty status. Any service member observing an unconscious and/or ill, injured, or wounded person must carefully and skillfully evaluate him to determine the first aid measures required to prevent further injury or death. He should seek help from medical personnel as soon as possible, but must not interrupt his evaluation of the casualty or fail to administer first aid measures. A second service member may be sent to find medical help. One of the cardinal principles for assisting a casualty is that you (the initial rescuer) must continue the evaluation and first aid measures, as the tactical situation permits, until another individual relieves you. If, during any part of the evaluation, the casualty exhibits the conditions (such as shock) for which the service member is checking, the service member must stop the evaluation and immediately administer first aid. In a chemical environment, the service member should not evaluate the casualty until both the individual and the casualty have been masked. If it is suspected that a nerve agent was used, administer the casualty’s own nerve agent antidote autoinjector. After providing first aid, the service member must proceed with the evaluation and continue to monitor the casualty for further complications until relieved by medical personnel. WARNING Do not use your own nerve agent antidote autoinjector on the casualty. NOTE Remember, when evaluating and/or administering first aid to a casualty, you should seek medical aid as soon as possible. DO NOT stop first aid measures, but if the situation allows, send another service member to find medical aid. 1-9 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. To evaluate a casualty, perform the following steps: (1) Check the casualty for responsiveness. This is done by gently shaking or tapping him while calmly asking, “Are you OK?” Watch for a response. If the casualty does not respond, go to step (2). If the casualty responds, continue with the evaluation. (a) If the casualty is conscious, ask him where he feels different than usual or where it hurts. Ask him to identify the location of pain if he can, or to identify the area in which there is no feeling. (b) If the casualty is conscious but is choking and cannot talk, stop the evaluation and begin first aid measures. Refer to paragraphs 2-10 and 2-11 for specific information on opening the airway. WARNING If a broken back or neck is suspected, do not move the casualty unless his life is in immediate danger (such as close to a burning vehicle). Movement may cause permanent paralysis or death. (2) Check for breathing. (Refer to paragraph 2-6 for this procedure.) (a) If the casualty is breathing, proceed to step (3). (b) If the casualty is not breathing, stop the evaluation and begin first aid measures to attempt to ventilate the casualty. Attempt to open the airway, if an airway obstruction is apparent, clear the airway obstruction, then ventilate (see paragraphs 2-10 and 2-11). (c) After successfully ventilating the casualty, proceed to step (3). (3) Check for pulse. (Refer to paragraph 1-3c(2) for specific methods.) If a pulse is present and the casualty is breathing, proceed to step (4). (a) If a pulse is present, but the casualty is still not breathing, start rescue breathing. (b) If a pulse is not present, seek medical personnel for help. 1-10 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (4) Check for bleeding. Look for spurts of blood or bloodsoaked clothes. Also check for both entry and exit wounds. If the casualty is bleeding from an open wound, stop the evaluation and begin first aid procedures as follows for a— (a) Wound of the arm or leg (refer to paragraphs 2-16 through 2-18 for information on putting on a field or pressure dressing). (b) Partial or complete amputation, apply dressing (refer to paragraph 2-16 to 2-18) and then apply tourniquet if bleeding is not stopped (refer to paragraph 2-20 for information on putting on a tourniquet). (c) Open head wound (refer to paragraph 3-10 for information on applying a dressing to an open head wound). (d) Open chest wound (refer to paragraph 3-5 for information on applying a dressing to an open chest wound). (e) Open abdominal wound (refer to paragraph 3-7 for information on applying a dressing to an open abdominal wound). WARNING In a chemically contaminated area, do not expose the wounds. Apply field dressing and then pressure dressing over wound area as needed. (5) Check for shock. (Refer to paragraph 2-24 for first aid measures for shock.) If the signs and symptoms of shock are present, stop the evaluation, and begin first aid measures immediately. The following are the nine signs and symptoms of shock. (a) Sweaty but cool skin (clammy skin). (b) Paleness of skin. (In dark-skinned service members look for a grayish cast to the skin.) (c) Restlessness or nervousness. (d) Thirst. (e) Loss of blood (bleeding). 1-11 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (f) Confusion (does not seem aware of surroundings). (g) Faster than normal breathing rate. (h) Blotchy or bluish skin, especially around the mouth. (i) Nausea or vomiting. WARNING Leg fractures must be splinted before elevating the legs as a first aid measure for shock. (6) Check for fractures. (a) Check for the following signs and symptoms of a back or neck injury and perform first aid procedures as necessary. • Pain or tenderness of the back or neck area. • Cuts or bruises on the back or neck area. • Inability of a casualty to move or decreased sensation to extremities (paralysis or numbness). • Ask about ability to move (paralysis). • Touch the casualty’s arms and legs and ask whether he can feel your hand (numbness). • Unusual body or limb position. (b) Immobilize any casualty suspected of having a back or neck injury by doing the following: • Tell the casualty not to move. • If a back injury is suspected, place padding (rolled or folded to conform to the shape of the arch) under the natural arch of the casualty’s back. (For example, a blanket/poncho may be used as padding.) 1-12 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) WARNING Do not move casualty to place padding. • If a neck injury is suspected, immediately immobilize (manually) the head and neck. Place a roll of cloth under the casualty’s neck, and put weighted boots (filled with dirt or sand) or rocks on both sides of his head. (c) Check the casualty’s arms and legs for open or closed fractures. • Check for open fractures by looking for— • Bleeding. • Bones sticking through the skin. • Check for pulse. • Check for closed fractures by looking for— • Swelling. • Discoloration. • Deformity. • Unusual body position. • Check for pulse. (d) Stop the evaluation and begin first aid measures if a fracture to an arm or leg is suspected. Refer to Chapter 4 for information on splinting a suspected fracture. (e) Check for signs/symptoms of fractures of other body areas (for example, shoulder or hip) and provide first aid as necessary. (7) Check for burns. Look carefully for reddened, blistered, or charred skin; also check for singed clothing. If burns are found, stop the evaluation and begin first aid procedures. Refer to paragraph 3-9 for information on giving first aid for burns. 1-13 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE Burns to the upper torso and face may cause respiratory complications. When evaluating the casualty, look for singed nose hair, soot around the nostrils, and listen for abnormal breath sounds or difficulty breathing. (8) Check for possible head injury. (a) Look for the following signs and symptoms: • Unequal pupils. • Fluid from the ear(s), nose, mouth, or injury site. • Slurred speech. • Confusion. • Sleepiness. • Loss of memory or consciousness. • Staggering in walking. • Headache. • Dizziness. • Nausea or vomiting. • Paralysis. • Convulsions or twitches. • Bruising around the eyes and behind the ears. (b) If a head injury is suspected, continue to watch for signs which would require performance of rescue breathing, first aid measures for shock, or control of bleeding; seek medical aid. Refer to paragraph 3-10 for information on first aid measures for head injuries. 2-1 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) CHAPTER 2 BASIC MEASURES FOR FIRST AID 2-1. General Several conditions that require immediate attention are an inadequate airway, lack of breathing, and excessive loss of blood (circulation). A casualty without a clear airway or who is not breathing may die from lack of oxygen. Excessive loss of blood may lead to shock, and shock can lead to death; therefore, you must act immediately to control the loss of blood. All wounds are considered to be contaminated, since infection-producing organisms (germs) are always present on the skin and clothing, and in the soil, water, and air. Any missile or instrument (such as a bullet, shrapnel, knife, or bayonet) causing a wound pushes or carries the germs into that wound. Infection results as these organisms multiply. That a wound is contaminated does not lessen the importance of protecting it from further contamination. You must dress and bandage a wound as soon as possible to prevent further contamination. NOTE It is also important that you attend to any airway, breathing, or bleeding problems IMMEDIATELY because these problems, if left unattended, may become life threatening. Section I. OPEN THE AIRWAY AND RESTORE BREATHING 2-2. Breathing Process All humans must have oxygen to live. Through the breathing process, the lungs draw oxygen from the air and put it into the blood. The heart pumps the blood through the body to be used by the cells that require a constant supply of oxygen. Some cells are more dependent on a constant supply of oxygen than others. For example, cells of the brain may die within 4 to 6 minutes without oxygen. Once these cells die, they are lost forever since they do not regenerate. This could result in permanent brain damage, paralysis, or death. 2-3. Assessment of and Positioning the Casualty a. CHECK for responsiveness (Figure 2-1A)—establish whether the casualty is conscious by gently shaking him and asking, “Are you OK?” 2-2 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. CALL for help (Figure 2-1B). c. POSITION the unconscious casualty so that he is lying on his back and on a firm surface (Figure 2-1C). WARNING If the casualty is lying on his chest (prone position), cautiously roll the casualty as a unit so that his body does not twist (which may further complicate a back, neck, or spinal injury). Figure 2-1. Assessment (Illustrated A—C). (1) Straighten the casualty’s legs. Take the casualty’s arm that is nearest to you and move it so that it is straight and above his head. Repeat the procedure for the other arm. A B C 2-3 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (2) Kneel beside the casualty with your knees near his shoulders (leave space to roll his body) (Figure 2-1B). Place one hand behind his head and neck for support. With your other hand, grasp the casualty under his far arm (Figure 2-1C). (3) Roll the casualty towards you using a steady, even pull. His head and neck should stay in line with his back. (4) Return the casualty’s arms to his side. Straighten his legs. Reposition yourself so that you are now kneeling at the level of the casualty’s shoulders. However, if a neck injury is suspected and the jaw-thrust technique will be used, kneel at the casualty’s head, looking towards his feet. 2-4. Opening the Airway of an Unconscious or Not Breathing Casualty The tongue is the single most common cause of an airway obstruction (Figure 2-2). In most cases, simply using the head-tilt/chin-lift technique can clear the airway. This action pulls the tongue away from the air passage in the throat (Figure 2-3). Figure 2-2. Airway blocked by tongue. Figure 2-3. Airway opened by extending neck. a. Call for help and then position the casualty. Move (roll) the casualty onto his back (Figure 2-1C). (Refer to paragraph 2-3c for information on positioning the casualty.) 2-4 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE Perform finger sweep. If foreign material or vomitus is visible in the mouth, it should be removed, but do not spend an excessive amount of time doing so. b. Open the airway using the jaw-thrust or head-tilt/chin-lift technique. CAUTION The head-tilt/chin-lift technique is an important procedure in opening the airway; however, use extreme care because excess force in performing this maneuver may cause further spinal injury. In a casualty with a suspected neck injury or severe head trauma, the safest approach to opening the airway is the jaw-thrust technique because in most cases it can be accomplished without extending the neck. (1) Perform the jaw-thrust technique. The jaw-thrust may be accomplished by the rescuer grasping the angles of the casualty’s lower jaw and lifting with both hands, one on each side, displacing the jaw forward and up (Figure 2-4). The rescuer’s elbows should rest on the surface on which the casualty is lying. If the lips close, the lower lip can be retracted with the thumb. If mouth-to-mouth breathing is necessary, close the nostrils by placing your cheek tightly against them. The head should be carefully supported without tilting it backwards or turning it from side to side. If this is unsuccessful, the head should be tilted back very slightly. The jaw-thrust is the safest first approach to opening the airway of a casualty who has a suspected neck injury because in most cases it can be accomplished without extending the neck. Figure 2-4. Jaw-thrust technique of opening airway. 2-5 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (2) Perform the head-tilt/chin-lift technique. Place one hand on the casualty’s forehead and apply firm, backward pressure with the palm to tilt the head back. Place the fingertips of the other hand under the bony part of the lower jaw and lift, bringing the chin forward. The thumb should not be used to lift the chin (Figure 2-5). NOTE The fingers should not press deeply into the soft tissue under the chin because the airway may be obstructed. Figure 2-5. Head-tilt/chin-lift technique of opening airway. (3) Check for breathing (while maintaining an airway). After establishing an open airway, it is important to maintain that airway in an open position. Often the act of just opening and maintaining the airway will allow the casualty to breathe properly. Once the rescuer uses one of the techniques to open the airway (jaw-thrust or head-tilt/chin-lift), he should maintain that head position to keep the airway open. Failure to maintain the open airway will prevent the casualty from receiving an adequate supply of oxygen. Therefore, while maintaining an open airway the rescuer should check for breathing by observing the casualty’s chest and performing the following actions within 3 to 5 seconds: (a) LOOK for the chest to rise and fall. (b) LISTEN for air escaping during exhalation by placing your ear near the casualty’s mouth. (c) FEEL for the flow of air on your cheek (see Figure 2-6). (d) PERFORM rescue breathing if the casualty does not resume breathing spontaneously. 2-6 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE If the casualty resumes breathing, monitor and maintain the open airway. He should be transported to an MTF, as soon as practical. 2-5. Rescue Breathing (Artificial Respiration) a. If the casualty does not promptly resume adequate spontaneous breathing after the airway is open, rescue breathing (artificial respiration) must be started. Be calm! Think and act quickly! The sooner you begin rescue breathing, the more likely you are to restore the casualty’s breathing. If you are in doubt whether the casualty is breathing, give artificial respiration, since it can do no harm to a person who is breathing. If the casualty is breathing, you can feel and see his chest move. If the casualty is breathing, you can feel and hear air being expelled by putting your hand or ear close to his mouth and nose. b. There are several methods of administering rescue breathing. The mouth-to-mouth method is preferred; however, it cannot be used in all situations. If the casualty has a severe jaw fracture or mouth wound or his jaws are tightly closed by spasms, use the mouth-to-nose method. 2-6. Preliminary Steps—All Rescue Breathing Methods a. Establish unresponsiveness. Call for help. Turn or position the casualty. b. Open the airway. c. Check for breathing by placing your ear over the casualty’s mouth and nose, and looking toward his chest. (1) LOOK for rise and fall of the casualty’s chest (Figure 2-6). (2) LISTEN for sounds of breathing. (3) FEEL for breath on the side of your face. If the chest does not rise and fall and no air is exhaled, then the casualty is not breathing. (4) PERFORM rescue breathing if the casualty is not breathing. 2-7 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE Although the rescuer may notice that the casualty is making respiratory efforts, the airway may still be obstructed and opening the airway may be all that is needed. If the casualty resumes breathing, the rescuer should continue to maintain an open airway. Figure 2-6. Check for breathing. 2-7. Mouth-to-Mouth Method In this method of rescue breathing, you inflate the casualty’s lungs with air from your lungs. This can be accomplished by blowing air into the person’s mouth. The mouth-to-mouth rescue breathing method is performed as follows: a. If the casualty is not breathing, place your hand on his forehead, and pinch his nostrils together with the thumb and index finger of this hand. Let this same hand exert pressure on his forehead to maintain the backward head tilt and maintain an open airway. With your other hand, keep your fingertips on the bony part of the lower jaw near the chin and lift (Figure 2-7). Figure 2-7. Head tilt/chin lift. 2-8 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE If you suspect the casualty has a neck injury and you are using the jaw-thrust technique, close the nostrils by placing your cheek tightly against them. b. Take a deep breath and place your mouth (in an airtight seal) around the casualty’s mouth (Figure 2-8). (If the injured person is small, cover both his nose and mouth with your mouth, sealing your lips against the skin of his face.) Figure 2-8. Rescue breathing. c. Blow two full breaths into the casualty’s mouth (1 to 1 1/2 seconds per breath), taking a breath of fresh air each time before you blow. Watch out of the corner of your eye for the casualty’s chest to rise. If the chest rises, sufficient air is getting into the casualty’s lungs. Therefore, proceed as described in step (1). If the chest does not rise, do the following (a, b, and c below) and then attempt to ventilate again. (1) Take corrective action immediately by reestablishing the airway. Make sure that air is not leaking from around your mouth or out of the casualty’s pinched nose. (2) Reattempt to ventilate. (3) If the chest still does not rise, take the necessary action to open an obstructed airway (paragraph 2-10). NOTE If the initial attempt to ventilate the casualty is unsuccessful, reposition the casualty’s head and repeat rescue breathing. Improper chin and head positioning is the most common cause of difficulty with ventilation. If the casualty cannot be ventilated after repositioning the head, proceed with foreign-body airway obstruction maneuvers (see paragraph 2-10). 2-9 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (4) After giving two slow breaths, which cause the chest to rise, attempt to locate a pulse on the casualty. Feel for a pulse on the side of the casualty’s neck closest to you by placing the first two fingers (index and middle fingers) of your hand on the groove beside the casualty’s Adam’s apple (carotid pulse) (Figure 2-9). (Your thumb should not be used for pulse taking because you may confuse your pulse beat with that of the casualty.) Maintain the airway by keeping your other hand on the casualty’s forehead. Allow 5 to 10 seconds to determine if there is a pulse. Figure 2-9. Placement of fingers to detect pulse. (a) If signs of circulation are present and a pulse is found and the casualty is breathing—STOP; allow the casualty to breathe on his own. If possible, keep him warm and comfortable. (b) If a pulse is found and the casualty is not breathing, continue rescue breathing. (c) If a pulse is not found, seek medically trained personnel for help as soon as possible. 2-8. Mouth-to-Nose Method Use this method if you cannot perform mouth-to-mouth rescue breathing because the casualty has a severe jaw fracture or mouth wound or his jaws are tightly closed by spasms. The mouth-to-nose method is performed in the same way as the mouth-to-mouth method except that you blow into the nose while you hold the lips closed with one hand at the chin. You then remove your mouth to allow the casualty to exhale passively. It may be necessary to separate the casualty’s lips to allow the air to escape during exhalation. 2-9. Heartbeat If a casualty’s heart stops beating, you must immediately seek medical help. SECONDS COUNT! Stoppage of the heart is soon followed by cessation of 2-10 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) respiration unless it has occurred first. Be calm! Think and act! When a casualty’s heart has stopped, there is no pulse at all; the person is unconscious and limp, and the pupils of his eyes are open wide. When evaluating a casualty or when performing the preliminary steps of rescue breathing, feel for a pulse. If you DO NOT detect a pulse, seek medical help. 2-10. Airway Obstructions In order for oxygen from the air to flow to and from the lungs, the upper airway must be unobstructed. a. Upper airway obstructions often occur because— (1) The casualty’s tongue falls back into his throat while he is unconscious. The tongue falls back and obstructs the airway, it is not swallowed by the casualty. NOTE Ensure the correct positioning and maintenance of the open airway for an injured or unconscious casualty. (2) Foreign bodies become lodged in the throat. These obstructions usually occur while eating. Choking on food (usually meat) is associated with— • Attempting to swallow large pieces of poorly chewed food. • Drinking alcohol. • Slipping dentures. (3) The contents of the stomach are regurgitated and may block the airway. (4) Blood clots may form as a result of head and facial injuries. b. Upper airway obstruction may cause either partial or complete airway blockage. (1) Partial airway obstruction. The casualty may still have an air exchange. A good air exchange means that the casualty can cough 2-11 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) forcefully, though he may be wheezing between coughs. You, the rescuer, should not interfere, and should encourage the casualty to cough up the object obstructing his airway on his own. A poor air exchange may be indicated by weak coughing with a high pitched noise between coughs. Further, the casualty may show signs of shock (paragraph 1-6b[5]) indicating a need for oxygen. You should assist the casualty and treat him as though he had a complete obstruction. (2) Complete airway obstruction. A complete obstruction (no air exchange) is indicated if the casualty cannot speak, breathe, or cough at all. He may be clutching his neck and moving erratically. In an unconscious casualty, a complete obstruction is also indicated if after opening his airway you cannot ventilate him. 2-11. Opening the Obstructed Airway—Conscious Casualty Clearing a conscious casualty’s airway obstruction can be performed with the casualty either standing or sitting and by following a relatively simple procedure. WARNING Once an obstructed airway occurs, the brain will develop an oxygen deficiency resulting in unconsciousness. Death will follow rapidly if breathing is not promptly restored. a. Ask the casualty if he can speak or if he is choking. Check for the universal choking sign (Figure 2-10). Figure 2-10. Universal sign of choking. 2-12 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. If the casualty can speak, encourage him to attempt to cough; the casualty still has a good air exchange. If he is able to speak or cough effectively, DO NOT interfere with his attempts to expel the obstruction. c. Listen for high pitched sounds when the casualty breathes or coughs (poor air exchange). If there is poor air exchange or no breathing, CALL FOR HELP and immediately deliver manual thrusts (either an abdominal or chest thrust). NOTE The manual thrust with the hands centered between the waist and the rib cage is called an abdominal thrust (or Heimlich maneuver). The chest thrust (the hands are centered in the middle of the breastbone) is used only for an individual in the advanced stages of pregnancy, in the markedly obese casualty, or if there is a significant abdominal wound. (1) Apply abdominal thrusts. This can be accomplished by using the following procedures: (a) Stand behind the casualty and wrap your arms around his waist. (b) Make a fist with one hand and grasp it with the other. The thumb side of your fist should be against the casualty’s abdomen, in the midline and slightly above the casualty’s navel, but well below the tip of the breastbone (Figure 2-11). Figure 2-11. Anatomical view of abdominal thrust procedure. (c) Press the fists into the abdomen with a quick backward and upward thrust (Figure 2-12). 2-13 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-12. Profile view of abdominal thrust. (d) Each thrust should be a separate and distinct movement. NOTE Continue performing abdominal thrusts until the obstruction is expelled or the casualty becomes unresponsive. (e) If the casualty becomes unresponsive, call for help as you proceed with steps to open the airway, and perform rescue breathing. (Refer to paragraph 2-7 for information on how to perform mouth-to-mouth resuscitation.) (2) Apply chest thrusts. An alternate technique to the abdominal thrust is the chest thrust. This technique is useful when the casualty has an abdominal wound, when the casualty is pregnant, or when the casualty is so large that you cannot wrap your arms around the abdomen. To apply chest thrusts with casualty sitting or standing: (a) Stand behind the casualty and wrap your arms around his chest with your arms under his armpits. (b) Make a fist with one hand and place the thumb side of the fist in the middle of the breastbone (take care to avoid the tip of the breastbone and the margins of the ribs). (c) Grasp the fist with the other hand and exert thrusts (Figure 2-13). 2-14 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-13. Profile view of chest thrust. (d) Each thrust should be delivered slowly, distinctly, and with the intent of relieving the obstruction. (e) Perform chest thrusts until the obstruction is expelled or the casualty becomes unresponsive. (f) If the casualty becomes unresponsive, call for help as you proceed with steps to open the airway and perform rescue breathing. 2-12. Opening the Obstructed Airway—Casualty Lying Down or Unresponsive The following procedures are used to expel an airway obstruction in a casualty who is lying down, who becomes unconscious, or who is found unconscious (the cause unknown): • If a conscious casualty who is choking becomes unresponsive, call for help, open the airway, perform a finger sweep, and attempt rescue breathing (paragraphs 2-4 through 2-8). If you still cannot administer rescue breathing due to an airway blockage, then remove the airway obstruction using the procedures as in b below. • If a casualty is unresponsive when you find him (the cause unknown), assess or evaluate the situation, call for help, position the casualty on his back, open the airway, establish breathlessness, and attempt to perform rescue breathing (paragraphs 2-4 through 2-8). a. Open the airway and attempt rescue breathing (refer to paragraph 2-7 for information on how to perform mouth-to-mouth resuscitation). 2-15 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. If still unable to ventilate the casualty, perform 6 to 10 manual (abdominal or chest) thrusts. (1) To perform the abdominal thrusts: (a) Kneel astride the casualty’s thighs (Figure 2-14). Figure 2-14. Abdominal thrust on unresponsive casualty. (b) Place the heel of one hand against the casualty’s abdomen (in the midline slightly above the navel but well below the tip of the breastbone). Place your other hand on top of the first one. Point your fingers toward the casualty’s head. (c) Press into the casualty’s abdomen with a quick, forward and upward thrust. You can use your body weight to perform the maneuver. Deliver each thrust quickly and distinctly. (d) Repeat the sequence of abdominal thrusts, finger sweep, and rescue breathing (attempt to ventilate) as long as necessary to remove the object from the obstructed airway. (e) If the casualty’s chest rises, proceed to feeling for pulse. (2) To perform chest thrusts: (a) Place the unresponsive casualty on his back, face up, and open his mouth. Kneel close to the side of the casualty’s body. 1. Locate the lower edge of the casualty’s ribs with your fingers. Run the fingers up along the rib cage to the notch (Figure 2-15A). 2-16 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 2. Place the middle finger on the notch and the index finger next to the middle finger on the lower edge of the breastbone. Place the heel of the other hand on the lower half of the breastbone next to the two fingers (Figure 2-15B). 3. Remove the fingers from the notch and place that hand on top of the positioned hand on the breastbone, extending or interlocking the fingers (Figure 2-15C). 4. Straighten and lock your elbows with your shoulders directly above your hands without bending the elbows, rocking, or allowing the shoulders to sag. Apply enough pressure to depress the breastbone 1 1/2 to 2 inches, then release the pressure completely (Figure 2- 15D). Do this 6 to 10 times. Each thrust should be delivered quickly and distinctly. See Figure 2-16 for another view of the breastbone being depressed. Figure 2-15. Hand placement for chest thrust (Illustrated A-D). 2-17 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-16. Breastbone depressed 1 1/2 to 2 inches. (b) Repeat the sequence of chest thrust, finger sweep, and rescue breathing as long as necessary to clear the object from the obstructed airway. See paragraph (3) below. (c) If the casualty’s chest rises, proceed to feeling for his pulse. (3) If you still cannot administer rescue breathing due to an airway obstruction, then remove the airway obstruction using the procedures in steps (a) and (b) below. (a) Place the casualty on his back, face up, turn the unresponsive casualty as a unit, and call out for help. (b) Perform finger sweep, keep casualty face up, use tongue-jaw lift to open mouth. 1. Open the casualty’s mouth by grasping both his tongue and lower jaw between your thumb and fingers and lifting (tonguejaw lift) (Figure 2-17). If you are unable to open his mouth, cross your fingers and thumb (crossed-finger method) and push his teeth apart (Figure 2-18) by pressing your thumb against his upper teeth and pressing your finger against his lower teeth. Figure 2-17. Opening casualty’s mouth (tongue-jaw lift). 2-18 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-18. Opening casualty’s mouth (crossed-finger method). 2. Insert the index finger of the other hand down along the inside of his cheek to the base of the tongue. Use a hooking motion from the side of the mouth toward the center to dislodge the foreign body (Figure 2-19). Figure 2-19. Using finger to dislodge a foreign body. WARNING Take care not to force the object deeper into the airway by pushing it with the finger. Section II. STOP THE BLEEDING AND PROTECT THE WOUND 2-13. General The longer a service member bleeds from a major wound, the less likely he will be able to survive his injuries. It is, therefore, important that the first aid provider promptly stop the external bleeding. 2-19 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 2-14. Clothing In evaluating the casualty for location, type, and size of the wound or injury, cut or tear his clothing and carefully expose the entire area of the wound. This procedure is necessary to properly visualize injury and avoid further contamination. Clothing stuck to the wound should be left in place to avoid further injury. DO NOT touch the wound; keep it as clean as possible. WARNING DO NOT REMOVE protective clothing in a chemical environment. Apply dressings over the protective clothing. 2-15. Entrance and Exit Wounds Before applying the dressing, carefully examine the casualty to determine if there is more than one wound. A missile may have entered at one point and exited at another point. The EXIT wound is usually LARGER than the entrance wound. WARNING The casualty should be continually monitored for development of conditions which may require the performance of necessary basic lifesaving measures, such as clearing the airway and mouth-to-mouth resuscitation. All open (or penetrating) wounds should be checked for a point of entry and exit and first aid measures applied accordingly. WARNING If the missile lodges in the body (fails to exit), DO NOT attempt to remove it or probe the wound. Apply a dressing. If there is an object extending from (impaled in) the wound, DO NOT remove the object. Apply a dressing around the object and use additional improvised bulky materials/dressings (use the cleanest material available) to build up the area around the object to stabilize the object and prevent further injury. Apply a supporting bandage over the bulky materials to hold them in place. 2-20 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 2-16. Field Dressing a. Use the casualty’s field dressing; remove it from the wrapper and grasp the tails of the dressing with both hands (Figure 2-20). Figure 2-20. Grasping tails of dressing with both hands. WARNING DO NOT touch the white (sterile) side of the dressing, and DO NOT allow it to come in contact with any surface other than the wound. b. Hold the dressing directly over the wound with the white side down. Pull the dressing open (Figure 2-21) and place it directly over the wound (Figure 2-22). Figure 2-21. Pulling dressing open. Figure 2-22. Placing dressing directly on wound. 2-21 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) c. Hold the dressing in place with one hand. Use the other hand to wrap one of the tails around the injured part, covering about one-half of the dressing (Figure 2-23). Leave enough of the tail for a knot. If the casualty is able, he may assist by holding the dressing in place. Figure 2-23. Wrapping tail of dressing around injured part. d. Wrap the other tail in the opposite direction until the remainder of the dressing is covered. The tails should seal the sides of the dressing to keep foreign material from getting under it. e. Tie the tails into a nonslip knot over the outer edge of the dressing (Figure 2-24). DO NOT TIE THE KNOT OVER THE WOUND. In order to allow blood to flow to the rest of an injured limb, tie the dressing firmly enough to prevent it from slipping but without causing a tourniquetlike effect; that is, the skin beyond the injury should not becomes cool, blue, or numb. Figure 2-24. Tails tied into nonslip knot. 2-17. Manual Pressure a. If bleeding continues after applying the sterile field dressing, direct manual pressure may be used to help control bleeding. Apply such pressure by placing a hand on the dressing and exerting firm pressure for 5 to 10 minutes (Figure 2-25). The casualty may be asked to do this himself if he is conscious and can follow instructions. 2-22 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-25. Direct manual pressure applied. b. Elevate an injured limb slightly above the level of the heart to reduce the bleeding (Figure 2-26). Figure 2-26. Injured limb elevated. WARNING DO NOT elevate a suspected fractured limb unless it has been properly splinted. c. If the bleeding stops, check shock; administer first aid for shock as necessary. If the bleeding continues, apply a pressure dressing. 2-18. Pressure Dressing Pressure dressings aid in blood clotting and compress the open blood vessel. If bleeding continues after the application of a field dressing, manual pressure, and elevation, then a pressure dressing must be applied as follows: a. Place a wad of padding on top of the field dressing, directly over the wound (Figure 2-27). Keep the injured extremity elevated. 2-23 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-27. Wad of padding on top of field dressing. NOTE Improvised bandages may be made from strips of cloth. These strips may be made from T-shirts, socks, or other garments. b. Place an improvised dressing (or cravat, if available) over the wad of padding (Figure 2-28). Wrap the ends tightly around the injured limb, covering the previously placed field dressing (Figure 2-29). Figure 2-28. Improvised dressing over wad of padding Figure 2-29. Ends of improvised dressing wrapped tightly around limb. c. Tie the ends together in a nonslip knot, directly over the wound site (Figure 2-30). DO NOT tie so tightly that it has a tourniquet-like effect. If bleeding continues and all other measures have failed, or if the limb is severed, then apply a tourniquet. Use the tourniquet as a LAST RESORT. When the bleeding stops, check for shock; administer first aid for shock as necessary. 2-24 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-30. Ends of improvised dressing tied together in nonslip knot. NOTE Distal end of wounded extremities (fingers and toes) should be checked periodically for adequate circulation. The dressing must be loosened if the extremity becomes cool, blue, or numb. NOTE If bleeding continues and all other measures have failed (dressings and covering wound, applying direct manual pressure, elevating the limb above the heart level, and applying a pressure dressing while maintaining limb elevation) then apply digital pressure (see paragraph 2-19). 2-19. Digital Pressure Digital pressure (often called “pressure points”) is an alternative method to control bleeding. This method uses pressure from the fingers, thumbs, or hands to press at the site or point where a main artery supplying the wounded area lies near the skin surface or over bone (Figure 2-31). This pressure may help shut off or slow down the flow of blood from the heart to the wound and is used in combination with direct pressure and elevation. It may help in instances where bleeding is not easily controlled, where a pressure dressing has not yet been applied, or where pressure dressings are not readily available. 2-25 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-31. Digital pressure (pressure with fingers, thumbs or hands). 2-20. Tourniquet DANGER A tourniquet is only used on an arm or leg where there is a danger of the casualty losing his life (bleeding to death). A tourniquet is a constricting band placed around an arm or leg to control bleeding. A service member whose arm or leg has been completely amputated may not be bleeding when first discovered, but a tourniquet should be applied anyway. This absence of bleeding is due to the body’s normal defenses (contraction or clotting of blood vessels) as a result of the amputation, but 2-26 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) after a period of time bleeding will start as the blood vessels relax or the clot may be knocked loose by moving the casualty. Bleeding from a major artery of the thigh, lower leg, or arm and bleeding from multiple arteries (which occurs in a traumatic amputation) may prove to be beyond control by manual pressure. If the pressure dressing (see paragraph 2-18, above) under firm hand pressure becomes soaked with blood and the wound continues to bleed, apply a tourniquet. WARNING Casualty should be continually monitored for development of conditions which may require the performance of necessary basic lifesaving measures, such as: clearing the airway, performing mouth-tomouth resuscitation, preventing shock, and/or bleeding control. All open (or penetrating) wounds should be checked for a point of entry or exit and treated accordingly. The tourniquet should not be used unless a pressure dressing has failed to stop the bleeding or an arm or leg has been cut off. On occasion, tourniquets have injured blood vessels and nerves. If left in place too long, a tourniquet can cause loss of an arm or leg. Once applied, it must stay in place, and the casualty must be taken to the nearest MTF as soon as possible. DO NOT loosen or release a tourniquet after it has been applied as release could precipitate bleeding and potentially lead to shock. a. Improvising a Tourniquet. In the absence of a specially designed tourniquet, a tourniquet may be made from a strong, pliable material, such as gauze or muslin bandages, clothing, or cravats. An improvised tourniquet is used with a rigid stick-like object. To minimize skin damage, ensure that the improvised tourniquet is at least 2 inches wide. WARNING The tourniquet must be easily identified or easily seen. WARNING DO NOT use wire or shoestring for a tourniquet band. 2-27 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. Placing the Improvised Tourniquet. (1) Place the tourniquet around the limb, between the wound and the body trunk (or between the wound and the heart). Never place it directly over a wound, a fracture, or joint. Tourniquets, for maximum effectiveness, should be placed on the upper arm or above the knee on the thigh (Figure 2-32). Figure 2-32. Tourniquet above knee. (2) The tourniquet should be well-padded. If possible, place the tourniquet over the smoothed sleeve or trouser leg to prevent the skin from being pinched or twisted. If the tourniquet is long enough, wrap it around the limb several times, keeping the material as flat as possible. Damaging the skin may deprive the surgeon of skin required to cover an amputation. Protection of the skin also reduces pain. c. Applying the Tourniquet. (1) Tie a half-knot. (A half-knot is the same as the first part of tying a shoe lace.) (2) Place a stick (or similar rigid object) on top of the halfknot (Figure 2-33). Figure 2-33. Rigid object on top of half-knot. 2-28 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (3) Tie a full knot over the stick (Figure 2-34). Figure 2-34. Full knot over rigid object. (4) Twist the stick (Figure 2-35) until the tourniquet is tight around the limb and/or the bright red bleeding has stopped. In the case of amputation, dark oozing blood may continue for a short time. This is the blood trapped in the area between the wound and tourniquet. Figure 2-35. Stick twisted. (5) Fasten the tourniquet to the limb by looping the free ends of the tourniquet over the ends of the stick. Then bring the ends around the limb to prevent the stick from loosening. Tie them together on the side of the limb (Figure 2-36). Figure 2-36. Tie free ends on side of limb. NOTE Other methods of securing the stick may be used as long as the stick does not unwind and no further injury results. 2-29 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE If possible, save and transport any severed (amputated) limbs or body parts with (but out of sight of) the casualty. (6) DO NOT cover the tourniquet—you should leave it in full view. If the limb is missing (total amputation), apply a dressing to the stump. All wounds should have a dressing to protect the wound from contamination. (7) Mark the casualty’s forehead with a “T” and the time to indicate a tourniquet has been applied. If necessary, use the casualty’s blood to make this mark. (8) Check and treat for shock. (9) Seek medical aid. CAUTION Only appropriately skilled medical personnel may adjust or otherwise remove/release the tourniquet in the appropriate setting. Section III. CHECK FOR SHOCK AND ADMINISTER FIRST AID MEASURES 2-21. General The term shock has a variety of meanings. In medicine, it refers to a collapse of the body’s cardiovascular system which includes an inadequate supply of blood to the body’s tissues. Shock stuns and weakens the body. When the normal blood flow in the body is upset, death can result. Early recognition and proper first aid may save the casualty’s life. 2-22. Causes and Effects a. There are three basic mechanisms associated with shock. These are— 2-30 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) • The heart is damaged and fails to work as a pump. • Blood loss (heavy bleeding) causes the volume of fluid within the vascular system to be insufficient. • The blood vessels dilate (open wider) so that the blood within the system (even though it is a normal volume [the casualty is not bleeding or dehydrated]) is insufficient to provide adequate circulation within the body. b. Shock may be the result of a number of conditions. These include— • Dehydration. • Allergic reaction to foods, drugs, insect stings, and snakebites. • Significant loss of blood. • Reaction to the sight of a wound, blood, or other traumatic scene. • Traumatic injuries, such as— • Burns. • Gunshot or shrapnel wounds. • Crush injuries. • Blows to the body (which can cause broken bones or damage to internal organs). • Head injuries. • Penetrating wounds (such as from a knife, bayonet, or missile). 2-23. Signs and Symptoms of Shock Examine the casualty to see if he has any of the following signs and symptoms: • Sweaty but cool skin (clammy skin). 2-31 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) • Weak and rapid pulse. • Paleness of skin (in dark-skinned individuals they may have a grayish look to their skin). • Restlessness, nervousness. • Thirst. • Loss of blood (bleeding). • Confusion (or loss of awareness). • Faster-than-normal breathing rate. • Blotchy or bluish skin (especially around the mouth and lips). • Nausea and/or vomiting. 2-24. First Aid Measures for Shock In the field, the first aid procedures administered for shock are identical to procedures that would be performed to prevent shock. When treating a casualty, assume that shock is present or will occur shortly. By waiting until actual signs and symptoms of shock are noticeable, the rescuer may jeopardize the casualty’s life. a. Position the Casualty. (DO NOT move the casualty or his limbs if suspected fractures have not been splinted. See Chapter 4 for details.) (1) Move the casualty to cover, if cover is available and the situation permits. (2) Lay the casualty on his back. NOTE A casualty in shock from a chest wound or one who is experiencing breathing difficulty, may breathe easier in a sitting position. If this is the case, allow him to sit upright, but monitor carefully in case his condition worsens. (3) Elevate the casualty’s feet higher than the level of his heart. Use a stable object (field pack or rolled up clothing) so that his feet will not slip off (Figure 2-37). 2-32 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) WARNING DO NOT elevate legs if the casualty has an unsplinted broken leg, head injury, or abdominal injury. Figure 2-37. Clothing loosened and feet elevated. WARNING Check casualty for leg fracture(s) and splint, if necessary, before elevating his feet. For a casualty with an abdominal wound, place his knees in an upright (flexed) position. (4) Loosen clothing at the neck, waist, or wherever it may be binding. CAUTION DO NOT loosen or remove protective clothing in a chemical environment. (5) Prevent chilling or overheating. The key is to maintain body temperature. In cold weather, place a blanket or other like item over him to keep him warm and under him to prevent chilling (Figure 2-38). However, if a tourniquet has been applied, leave it exposed (if possible). In hot weather, place the casualty in the shade and protect him from becoming chilled; however, avoid the excessive use of blankets or other coverings. 2-33 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 2-38. Body temperature maintained. (6) Calm the casualty. Throughout the entire procedure of providing first aid for a casualty, the rescuer should reassure the casualty and keep him calm. This can be done by being authoritative (taking charge) and by showing self-confidence. Assure the casualty that you are there to help him. (7) Seek medical aid. b. Food and/or Drink. When providing first aid for shock, DO NOT give the casualty any food or drink. If you must leave the casualty or if he is unconscious, turn his head to the side to prevent him from choking if he vomits (Figure 2-39). Figure 2-39. Casualty’s head turned to side. c. Evaluate Casualty. Continue to evaluate the casualty until medical personnel arrives or the casualty is transported to an MTF. 3-1 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) CHAPTER 3 FIRST AID FOR SPECIFIC INJURIES 3-1. General Basic lifesaving steps are discussed in Chapters 1 and 2; they apply to first aid measures for all injuries. Some wounds and burns will require special precautions and procedures when applying these measures. This chapter discusses specific first aid procedures for wounds of the head, face, and neck; chest and stomach wounds; and burns. It also discusses the techniques for applying dressings and bandages to specific parts of the body. 3-2. Head, Neck, and Facial Injuries a. Head Injuries. (1) Head injuries range from minor abrasions or cuts on the scalp to severe brain injuries that may result in unconsciousness and sometimes death. Head injuries are classified as open or closed wounds. An open wound is one that is visible, has a break in the skin, and usually has evidence of bleeding. A closed wound may be visible (such as a depression in the skull) or the first aid provider may not be able to see any apparent injury (such as internal bleeding). Some head injuries result in unconsciousness; however, a service member may have a serious head wound and still be conscious. Casualties with head and neck injuries should be treated as though they also have a spinal injury. The casualty should not be moved until the head and neck is stabilized unless he is in immediate danger (such as close to a burning vehicle). (2) Prompt first aid measures should be initiated for casualties with suspected head and neck injuries. The conscious casualty may be able to provide information on the extent of his injuries. However, as a result of the head injury, he may be confused and unable to provide accurate information. The signs and symptoms a first aid provider might observe are— • Nausea and vomiting. • Convulsions or twitches. • Slurred speech. • Confusion and loss of memory. (Does he know who he is? Does he know where he is? Does he know what day it is?) • Recent unconsciousness. 3-2 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) • Dizziness. • Drowsiness. • Blurred vision, unequal pupils, or bruising (black eyes). • Paralysis (partial or full). • Complaint of headache. • Bleeding or other fluid discharge from the scalp, nose, or ears. • Deformity of the head (depression or swelling). • Staggering while walking. b. Neck Injuries. Neck injuries may result in heavy bleeding. Apply pressure above and below the injury, but do not interfere with the breathing process, and attempt to control the bleeding. Apply a dressing. Always evaluate the casualty for a possible neck fracture/spinal cord injury; if suspected, seek medical treatment immediately. NOTE Establish and maintain the airway in cases of facial or neck injuries. If a neck fracture or spinal cord injury is suspected, immobilize the injury and, if necessary, perform basic life support measures. c. Facial Injuries. Soft tissue injuries of the face and scalp are common. Abrasions (scrapes) of the skin cause no serious problems. Contusions (injury without a break in the skin) usually cause swelling. A contusion of the scalp looks and feels like a lump. Laceration (cut) and avulsion (torn away tissue) injuries are also common. Avulsions are frequently caused when a sharp blow separates the scalp from the skull beneath it. Because the face and scalp are richly supplied with blood vessels (arteries and veins), wounds of these areas usually bleed heavily. 3-3. General First Aid Measures a. General Considerations. The casualty with a head injury (or suspected head injury) should be continually monitored for the development of conditions that may require basic lifesaving measures. After initiating first 3-3 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) aid measures, request medical assistance and evacuation. If dedicated medical evacuation assets are not available, transport the casualty to an MTF as soon as the situation permits. The first aid provider should not attempt to remove a protruding object from the head or give the casualty anything to eat or drink. Further, the first aid provider should be prepared to— • Clear the airway. • Control bleeding (external). • Administer first aid measures for shock. • Keep the casualty warm. • Protect the wound. b. Unconscious Casualty. An unconscious casualty does not have control of all of his body’s functions and may choke on his tongue, blood, vomitus, or other substances. (Refer to Figure 2-39.) (1) Breathing. The brain requires a constant supply of oxygen. A bluish (or in an individual with dark skin—grayish) color of skin around the lips and nail beds indicates that the casualty is not receiving enough oxygen. Immediate action must be taken to clear the airway, to position the casualty on his side, or to initiate rescue breathing. (2) Bleeding. Bleeding from a head injury usually comes from blood vessels within the scalp. Bleeding can also develop inside the skull or within the brain. In most instances visible bleeding from the head can be controlled by application of the field first aid dressing. CAUTION DO NOT attempt to put unnecessary pressure on the wound or attempt to push any brain matter back into the head (skull). DO NOT apply a pressure dressing. c. Concussion. If an individual receives a heavy blow to the head or face, he may suffer a brain concussion (an injury to the brain that involves a temporary loss of some or all of the brain’s ability to function). For example, the casualty may not breathe properly for a short period of time, or he may become confused and stagger when he attempts to walk. Symptoms of a concussion may only last for a short period of time. However, 3-4 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) if a casualty is suspected of having suffered a concussion, he should be transported to an MTF as soon as conditions permit. d. Convulsions. Convulsions (seizures/involuntary jerking) may occur even after a mild head injury. When a casualty is convulsing, protect him from hurting himself. Take the following measures: (1) Ease him to the ground if he is standing or sitting. (2) Support his head and neck. (3) Maintain his airway. (4) Protect him from further injury (such as hitting close-by objects). NOTE DO NOT forcefully hold the arms and legs if they are jerking because this can lead to broken bones. DO NOT force anything between the casualty’s teeth—especially if they are tightly clenched because this may obstruct the casualty’s airway. Maintain the casualty’s airway if necessary. e. Brain Damage. In severe head injuries where brain tissue is protruding, leave the wound alone; carefully place a loose moistened dressing (moistened with sterile normal saline if available) and also a first aid dressing over the tissue to protect it from further contamination. DO NOT remove or disturb any foreign matter that may be in the wound. Position the casualty so that his head is higher than his body. Keep him warm and seek medical assistance immediately. NOTE If there is an object extending from the wound, DO NOT remove the object. Improvise bulky dressings from the cleanest material available and place this material around the protruding object for support, then apply the field dressing. 3-4. Chest Wounds Blunt trauma, bullet or missile wounds, stab wounds, or falls may cause chest injuries. These injuries can be serious and may cause death quickly if first aid is not administered in a timely manner. A casualty with a chest injury may 3-5 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) complain of pain in the chest or shoulder area; he may have difficulty breathing. His chest may not rise normally when he breathes. The injury may cause the casualty to cough up blood and to have a rapid or a weak heartbeat. A casualty with an open chest wound has a punctured chest wall. The sucking sound heard when he breathes is caused by air leaking into his chest cavity. This particular type of wound is dangerous and will collapse the injured lung (Figure 3-1). Breathing becomes difficult for the casualty because the wound is open. The service members life may depend upon how quickly you apply an occlusive dressing over the wound (refer to paragraph 3-5). Figure 3-1. Collapsed lung. 3-5. First Aid for Chest Wounds a. Evaluate the Casualty. Be prepared to perform first aid measures. These measures may include clearing the airway, rescue breathing, treatment for shock, and/or bleeding control. b. Expose the Wound. If appropriate, cut or remove the casualty’s clothing to expose the wound. Remember, DO NOT remove clothing that is stuck to the wound because additional injury may result. DO NOT attempt to clean the wound. NOTE Examine the casualty to see if there is an entry and exit wound. If there are two wounds (entry, exit), perform the same procedure for both wounds. Treat the more serious (heavier bleeding, larger) wound first. It may be necessary to improvise a dressing for the second wound by using strips of cloth, such as a torn T-shirt, or whatever material is available. Also, listen for sucking sounds to determine if the chest wall is punctured. 3-6 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) CAUTION If there is an object impaled in the wound, DO NOT remove it. Apply a dressing around the object and use additional improvised bulky materials/dressings (use the cleanest materials available) to build up the area around the object. Apply a supporting bandage over the bulky materials to hold them in place. CAUTION DO NOT REMOVE protective clothing in a chemical environment. Apply dressings over the protective clothing. c. Open the Casualty’s Field Dressing Plastic Wrapper. In cases where there is a sucking chest wound, the plastic wrapper is used with the field dressing to create an occlusive dressing. If a plastic wrapper is not available, or if an additional wound needs to be treated; cellophane, foil, the casualty’s poncho, or similar material may be used. The covering should be wide enough to extend 2 inches or more beyond the edges of the wound in all directions. (1) Tear open one end of the casualty’s plastic wrapper covering the field dressing. Be careful not to destroy the wrapper and DO NOT touch the inside of the wrapper. (2) Remove the inner packet (field dressing). (3) Complete tearing open the empty plastic wrapper using as much of the wrapper as possible to create a flat surface. d. Place the Wrapper Over the Wound. Place the inside surface of the plastic wrapper directly over the wound when the casualty exhales and hold it in place (Figure 3-2). The casualty may hold the plastic wrapper in place if he is able. Figure 3-2. Open chest wound sealed with an occlusive dressing. 3-7 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) e. Apply the Dressing to the Wound. (1) Use your free hand and shake open the field dressing (Figure 3-3). Figure 3-3. Shaking open the field dressing. (2) Place the white side of the dressing on the plastic wrapper covering the wound (Figure 3-4). Figure 3-4. Field dressing placed on plastic wrapper. NOTE Use the casualty’s field dressing, not your own. (3) Have the casualty breathe normally. (4) While maintaining pressure on the dressing, grasp one tail of the field dressing with the other hand and wrap it around the casualty’s back. If tape is available, tape three sides of the plastic wrapper to the chest wall to provide occlusive type dressing. Leave one side untapped to provide emergency escape for air that may build up in the chest. If tape is not available, secure wrapper on three sides with field dressing leaving the fourth side as a flap. (5) Wrap the other tail in the opposite direction, bringing both tails over the dressing (Figure 3-5). 3-8 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-5. Tails of field dressing wrapped around casualty in opposite direction. (6) Tie the tails into a square knot in the center of the dressing after the casualty exhales and before he inhales. This will aid in maintaining pressure on the bandage after it has been tied (Figure 3-6). Tie the dressing firmly enough to secure the dressing without interfering with the casualty’s breathing. Figure 3-6. Tails of dressing tied into square knot over center of dressing. NOTE When practical, apply direct manual pressure over the dressing for 5 to 10 minutes to help control the bleeding. f. Position the Casualty. Position the casualty on his injured side or in a sitting position, whichever makes breathing easier (Figure 3-7). Figure 3-7. Casualty positioned (lying) on injured side. 3-9 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) g. Seek Medical Assistance. Contact medical personnel. WARNING If an occlusive dressing has been improperly placed, air may enter the chest cavity with no means of escape. This causes a life-threatening condition called tension pneumothorax. If the casualty’s condition (for example, difficulty breathing, shortness of breath, restlessness, or blueness/grayness of the skin) worsens after placing the dressing, quickly lift or remove, and then replace the occlusive dressing. 3-6. Abdominal Wounds The most serious abdominal wound is one in which an object penetrates the abdominal wall and pierces internal organs or large blood vessels. In these instances, bleeding may be severe and death can occur rapidly. 3-7. First Aid for Abdominal Wounds a. Evaluate the Casualty. Be prepared to perform basic first aid measures. Always check for both entry and exit wounds. If there are two wounds (entry and exit), treat the wound that appears more serious first (for example, the heavier bleeding, protruding organs, larger wound, and so forth). It may be necessary to improvise dressings for the second wound by using strips of cloth, a T-shirt, or the cleanest material available. b. Position the Casualty. Place and maintain the casualty on his back with his knees in an upright (flexed) position (Figure 3-8). The kneesup position helps relieve pain, assists in the treatment of shock, prevents further exposure of the bowel (intestines) or abdominal organs, and helps relieve abdominal pressure by allowing the abdominal muscles to relax. Figure 3-8. Casualty positioned (lying) on back with knees (flexed) up. 3-10 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) c. Expose the Wound. (1) Remove the casualty’s loose clothing to expose the wound. However, DO NOT attempt to remove clothing that is stuck to the wound; removing it may cause further injury. CAUTION DO NOT REMOVE protective clothing in a chemical environment. Apply dressings over the protective clothing. (2) Gently pick up any organs that may be on the ground. Do this with a clean, dry dressing or with the cleanest available material. Place the organs on top of the casualty’s abdomen (Figure 3-9). Figure 3-9. Protruding organs placed near wound. NOTE DO NOT probe, clean, or try to remove any foreign object from the abdomen. DO NOT touch with bare hands any exposed organs. DO NOT push organs back inside the body. d. Apply the Field Dressing. Use the casualty’s field dressing, not your own. If the field dressing is not large enough to cover the entire wound, the plastic wrapper from the dressing may be used to cover the wound first (placing the field dressing on top). Open the plastic wrapper carefully without touching the inner surface. If necessary, other improvised dressings may be made from clothing, blankets, or the cleanest materials available. WARNING If there is an object extending from the wound, DO NOT remove it. Place as much of the wrapper over the wound as possible without dislodging or moving the object. DO NOT place the wrapper over the object. 3-11 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (1) Grasp the tails in both hands. (2) Hold the dressing with the white side down directly over the wound. DO NOT touch the white (sterile) side of the dressing or allow anything except the wound to come in contact with it. (3) Pull the dressing open and place it directly over the wound (Figure 3-10). If the casualty is able, he may hold the dressing in place. Figure 3-10. Dressing placed directly over the wound. (4) Hold the dressing in place with one hand and use the other hand to wrap one of the tails around the body. (5) Wrap the other tail in the opposite direction until the dressing is completely covered. Leave enough of the tail for a knot. (6) Loosely tie the tails with a square knot at the casualty’s side (Figure 3-11). Figure 3-11. Dressing applied and tails tied with a square knot. WARNING When the dressing is applied, DO NOT put pressure on the wound or exposed internal parts, because pressure could cause further injury (vomiting, ruptured intestines, and so forth). Therefore, tie the dressing ties (tails) loosely at casualty’s side, not directly over the dressing. 3-12 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (7) Tie the dressing firmly enough to prevent slipping without applying pressure to the wound site (Figure 3-12). Figure 3-12. Field dressing covered with improvised material and loosely tied. Field dressings can be covered with improvised reinforcement material (cravats, strips of torn T-shirt, or other cloth) for additional support and protection. Tie improvised bandage on the opposite side of the dressing ties firmly enough to prevent slipping but without applying additional pressure to the wound. CAUTION DO NOT give casualties with abdominal wounds food or water (moistening the lips is allowed). e. Seek Medical Assistance. Notify medical personnel. 3-8. Burn Injuries Burns often cause extreme pain, scarring, or even death. Before administering first aid, you must be able to recognize the type of burn. There are four types of burns: • Thermal burns caused by fire, hot objects, hot liquids, and gases; or by nuclear blast or fireball. • Electrical burns caused by electrical wires, current, or lightning. • Chemical burns caused by contact with wet or dry chemicals or white phosphorus (WP)—from marking rounds and grenades. • Laser burns (eye [ocular] injury). 3-13 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 3-9. First Aid for Burns a. Eliminate the Source of the Burn. The source of the burn must be eliminated before any evaluation of the casualty can occur and first aid administered. (1) Quickly remove the casualty from danger and cover the thermal burn with any large nonsynthetic material, such as a field jacket. If the casualty’s clothing is still on fire, roll the casualty on the ground to smother (put out) the flames (Figure 3-13). Figure 3-13. Casualty covered and rolled on ground. CAUTION Synthetic materials, such as nylon, may melt and cause further injury. (2) Remove the electrical burn casualty from the electrical source by turning off the electrical current. DO NOT attempt to turn off the electricity if the source is not close by. Speed is critical, so DO NOT waste unnecessary time. If the electricity cannot be turned off, wrap any nonconductive material (dry rope, clothing, wood, and so forth) around the casualty’s back and shoulders and drag the casualty away from the electrical source (Figure 3-14). DO NOT make body-to-body contact with the casualty or touch any wires because you could also become an electrical burn casualty. 3-14 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-14. Casualty removed from electrical source (using nonconductive material). WARNING High voltage electrical burns may cause temporary unconsciousness, difficulties in breathing, or difficulties with the heart (heartbeat). (3) Remove the chemical from the burned casualty. Remove liquid chemicals by flushing with as much water as possible. Remove dry chemicals by brushing off loose particles (DO NOT use the bare surface of your hand because you could become a chemical burn casualty) and then flush with large amounts of water, if available. If large amounts of water are not available, then NO water should be applied because small amounts of water applied to a dry chemical burn may cause a chemical reaction. When WP strikes the skin, smother with a wet cloth or mud. Keep WP covered with a wet material to exclude air; this should help prevent the particles from burning. (4) Remove the laser burn casualty from the source. When removing the casualty from the laser beam source, be careful not to enter the 3-15 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) beam or you may become a casualty. Never look directly at the beam source and if possible, wear appropriate eye protection. NOTE After the casualty is removed from the source of the burn, he should be evaluated for conditions requiring basic first aid measures. b. Expose the Burn. Cut and gently lift away any clothing covering the burned area, without pulling clothing over the burns. Leave in place any clothing that is stuck to the burn. If the casualty’s hands or wrists have been burned, remove jewelry if possible without causing further injury (rings, watches, and so forth) and place in his pockets. This prevents the necessity to cut off jewelry since swelling usually occurs as a result of a burn. CAUTION DO NOT lift or cut away clothing if in a chemical environment. Apply the dressing directly over the casualty’s protective clothing. DO NOT attempt to decontaminate skin where blisters have formed. c. Apply a Field Dressing to the Burn. (1) Grasp the tails of the casualty’s dressing in both hands. (2) Hold the dressing directly over the wound with the white side down, pull the dressing open, and place it directly over the wound. DO NOT touch the white (sterile) side of the dressing or allow anything except the wound to come in contact with it. If the casualty is able, he may hold the dressing in place. (3) Hold the dressing in place with one hand and use the other hand to wrap one of the tails around the limbs or the body. (4) Wrap the other tail in the opposite direction until the dressing is completely covered. (5) Tie the tails into a square knot over the outer edge of the dressing. The dressing should be applied lightly over the burn. Ensure that dressing is applied firmly enough to prevent it from slipping. 3-16 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE Use the cleanest improvised dressing material available if a field dressing is not available or if it is not large enough for the entire wound. d. Take the Following Precautions: • DO NOT place the dressing over the face or genital area. • DO NOT break the blisters. • DO NOT apply grease or ointments to the burns. • For electrical burns, check for both an entry and exit burn from the passage of electricity through the body. Exit burns may appear on any area of the body despite location of entry burn. • For burns caused by wet or dry chemicals, flush the burns with large amounts of water and cover with a dry dressing. • For burns caused by WP, flush the area with water, then cover with a wet material, dressing, or mud to exclude the air and keep the WP particles from burning. • For laser burns, apply a field dressing. • If the casualty is conscious and not nauseated, give him small amounts of water. e. Seek Medical Assistance. Notify medical personnel. 3-10. Dressings and Bandages a. Head Wounds. (1) Position the casualty. WARNING DO NOT move the casualty if you suspect he has sustained a neck, spine, or head injury (which produces any signs or symptoms other than minor bleeding). 3-17 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) • If the casualty has a minor (superficial) scalp wound and is conscious: • Have the casualty sit up (unless other injuries prohibit or he is unable to). • If the casualty is lying down and is not accumulating fluids or drainage in his throat, elevate his head slightly. • If the casualty is bleeding from or into his mouth or throat, turn his head to the side or position him on his side so that the airway will be clear. Avoid putting pressure on the wound and place him on his uninjured side (Figure 3-15). Figure 3-15. Casualty lying on side opposite injury. • If the casualty is unconscious or has a severe head injury, then suspect and treat him as having a potential neck or spinal injury, immobilize and DO NOT move the casualty. NOTE If the casualty is choking or vomiting or is bleeding from or into his mouth (thus compromising his airway), position him on his uninjured side to allow for drainage and to help keep his airway clear. WARNING If it is necessary to turn a casualty with a suspected neck/spine injury; roll the casualty gently onto his side, keeping the head, neck, and body aligned while providing support for the head and neck. DO NOT roll the casualty by yourself but seek assistance. Move him only if absolutely necessary, otherwise keep the casualty immobilized to prevent further damage to the neck/spine. 3-18 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (2) Expose the wound. Remove the casualty’s helmet (if necessary). In a nuclear, biological, and chemical (NBC) environment, the first aid provider must leave the casualty as much protection (such as protective mask, mission-oriented protective posture [MOPP] overgarments) as possible. What items of protective equipment can be removed is dependent upon the casualty’s injuries (where on the body and what type), the MOPP level, integrity of protective equipment (such as tears in the garment or mask seal), availability of chemical protective shelters, and the tactical situation. WARNING DO NOT attempt to clean the wound or remove a protruding object. NOTE Always use the casualty’s field dressing, not your own. (3) Apply a dressing to a wound of the forehead or back of head. To apply a dressing to a wound of the forehead or back of the head— (a) Remove the dressing from the wrapper. (b) Grasp the tails of the dressing in both hands. (c) Hold the dressing (white side down) directly over the wound. DO NOT touch the white (sterile) side of the dressing or allow anything except the wound to come in contact with it. (d) Place it directly over the wound. (e) Hold it in place with one hand. If the casualty is able, he may assist. (f) Wrap the first tail horizontally around the head; ensure the tail covers the dressing (Figure 3-16). Figure 3-16. First tail of dressing wrapped horizontally around head. 3-19 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (g) Hold the first tail in place and wrap the second tail in the opposite direction, covering the dressing (Figure 3-17). Figure 3-17. Second tail wrapped in opposite direction. (h) Tie a square knot and secure the tails at the side of the head, making sure they DO NOT cover the eyes or ears (Figure 3-18). Figure 3-18. Tails tied in square knot at side of head. (4) Apply a dressing to a wound on top of the head. To apply a dressing to a wound on top of the head— (a) Remove the dressing from the wrapper. (b) Grasp the tails of the dressing in both hands. (c) Hold it (white side down) directly over the wound. DO NOT touch the white (sterile) side of the dressing or allow anything except the wound to come in contact with it. (d) Place it over the wound (Figure 3-19). 3-20 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-19. Dressing placed over wound. (e) Hold it in place with one hand. If the casualty is able, he may assist. (f) Wrap one tail down under the chin (Figure 3-20), up in front of the ear, over the dressing, and in front of the other ear. Figure 3-20. One tail of dressing wrapped under chin. WARNING Ensure the tails remain wide and close to the front of the chin to avoid choking the casualty. 3-21 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (g) Wrap the remaining tail under the chin in the opposite direction and up the side of the face to meet the first tail (Figure 3-21). Figure 3-21. Remaining tail wrapped under chin in opposite direction. (h) Cross the tails (Figure 3-22), bringing one around the forehead (above the eyebrows) and the other around the back of the head (at the base of the skull) to a point just above and in front of the opposite ear, and tie them using a square knot (Figure 3-23). Figure 3-22. Tails of dressing crossed with one around forehead. Figure 3-23. Tails tied in square knot (in front of and above ear). 3-22 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (5) Apply a triangular bandage to the head. To apply a triangular bandage to the head— (a) Turn the base (longest side) of the bandage up and center its base on the center of the forehead, letting the point (apex) fall on the back of the neck (Figure 3-24A). (b) Take the ends behind the head and cross the ends over the apex. (c) Take them over the forehead and tie them (Figure 3-24B). (d) Tuck the apex behind the crossed part of the bandage or secure it with a safety pin, if available (Figure 3-24C). Figure 3-24. Triangular bandage applied to head (Illustrated A—C) (6) Apply a cravat bandage to the head. To apply a cravat bandage to the head— (a) Place the middle of the bandage over the dressing (Figure 3-25A). (b) Cross the two ends of the bandage in opposite directions completely around the head (Figure 3-25B). (c) Tie the ends over the dressing (Figure 3-25C). Figure 3-25. Cravat bandage applied to head (Illustrated A—C). 3-23 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) b. Eye Injuries. The eye is a vital sensory organ, and blindness is a severe physical handicap. Timely first aid of the eye may relieve pain and may also help to prevent shock, permanent eye injury, and possible loss of vision. Because the eye is very sensitive, any injury can be easily aggravated if it is improperly handled. Injuries of the eye may be quite severe. Cuts of the eyelids can appear to be very serious, but if the eyeball is not involved, a person’s vision usually will not be damaged. However, lacerations (cuts) of the eyeball can cause permanent damage or loss of sight. (1) Lacerated/torn eyelids. Lacerated eyelids may bleed heavily, but bleeding usually stops quickly. Cover the injured eye with a sterile dressing. DO NOT put pressure on the wound because you may injure the eyeball. Handle torn eyelids very carefully to prevent further injury. Place any detached pieces of the eyelid on a clean bandage or dressing and immediately send them with the casualty to the medical facility. (2) Lacerated eyeball (injury to the globe). Lacerations or cuts to the eyeball may cause serious and permanent eye damage. Cover the injury with a loose sterile dressing. DO NOT put pressure on the eyeball because additional damage may occur. An important point to remember is that when one eyeball is injured, you should immobilize both eyes. This is done by applying a bandage to both eyes. Because the eyes move together, covering both will lessen the chances of further damage to the injured eye. (However, in hazardous surroundings, leave uninjured eye uncovered to enable casualty to see.) CAUTION DO NOT apply pressure when there is a possible laceration of the eyeball. The eyeball contains fluid. Pressure applied over the eye will force the fluid out, resulting in permanent injury. APPLY PROTECTIVE DRESSING WITHOUT ADDED PRESSURE. (3) Extruded eyeballs. Service members may encounter casualties with severe eye injuries that include an extruded eyeball (eyeball out-of-socket). In such instances you should gently cover the extruded eye with a loose moistened dressing and also cover the unaffected eye. DO NOT bind or exert pressure on the injured eye while applying the dressing. Keep the casualty quiet, place him on his back, treat for shock, and evacuate him immediately. (4) Burns of the eyes. Chemical burns, thermal (heat) burns, and light burns can affect the eyes. 3-24 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (a) Chemical burns. Injuries from chemical burns require immediate first aid. Mainly acids or alkalies cause chemical burns. The first aid measures consist of flushing the eyes immediately with large amounts of water for at least 5 to 20 minutes, or as long as necessary to flush out the chemical and, once flushed, bandaging the eyes. If the burn is an acid burn, you should flush the eye for at least 5 to 10 minutes. If the burn is an alkali burn, you should flush the eye for at least 20 minutes. After the eye has been flushed evacuate the casualty immediately. (b) Thermal burns. When an individual suffers burns of the face from a fire, the eyes will close quickly due to extreme heat. This reaction is a natural reflex to protect the eyeballs; however, the eyelids remain exposed and are frequently burned. If a casualty receives burns of the eyelids or face— • DO NOT apply a dressing. • DO NOT touch. • SEEK medical assistance immediately. (c) Light burns. Exposure to intense light can burn an individual. Infrared rays, eclipse light (if the casualty has looked directly at the sun), or laser burns cause injuries of the exposed eyeball. Ultraviolet rays from arc welding can cause a superficial burn to the surface of the eye. These injuries are generally not painful but may cause permanent damage to the eyes. Immediate first aid is usually not required. Loosely bandaging the eyes may make the casualty more comfortable and protect his eyes from further injury caused by exposure to other bright lights or sunlight. CAUTION With impaled objects or significant sized foreign bodies, both eyes are usually bandaged to help secure the foreign body in the injured eye. In a battlefield environment, leave the uninjured eye uncovered so that the casualty can see. c. Side-of-Head or Cheek Wound. Facial injuries to the side of the head or the cheek may bleed profusely (Figure 3-26). Prompt action is necessary to ensure that the airway remains open and also to control the bleeding. It may be necessary to apply a dressing. To apply a dressing— (1) Remove the dressing from its wrapper. 3-25 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (2) Grasp the tails in both hands. (3) Hold the dressing directly over the wound with the white side down and place it directly on the wound (Figure 3-27A). DO NOT touch the white (sterile) side of the dressing or allow anything except the wound to come in contact with it. (4) Hold the dressing in place with one hand (the casualty may assist if able). Wrap the top tail over the top of the head and bring it down in front of the ear (on the side opposite the wound), under the chin (Figure 3-27B) and up over the dressing to a point just above the ear (on the wound side). Figure 3-26. Side of head or cheek wound. Figure 3-27. Dressing placed directly on wound. Top tail wrapped over top of head, down in front of ear, and under chin (Illustrated A—B). NOTE When possible, avoid covering the casualty’s ear with the dressing, as this will decrease his ability to hear. (5) Bring the second tail under the chin, up in front of the ear (on the side opposite the wound), and over the head to meet the other tail (on the wounded side) (Figure 3-28). 3-26 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-28. Bringing second tail under the chin. (6) Cross the two tails (on the wound side) (Figure 3-29) and bring one end across the forehead (above the eyebrows) to a point just in front of the opposite ear (on the uninjured side). Figure 3-29. Crossing the tails on the side of the wound. (7) Wrap the other tail around the back of the head (at the base of the skull), and tie the two ends just in front of the ear on the uninjured side with a square knot (Figure 3-30). Figure 3-30. Tying the tails of the dressing in a square knot. 3-27 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) d. Ear Injuries. Lacerated (cut) or avulsed (torn) ear tissue may not, in itself, be a serious injury. Bleeding, or the drainage of fluids from the ear canal, however, may be a sign of a head injury, such as a skull fracture. DO NOT attempt to stop the flow from the inner ear canal nor put anything into the ear canal to block it. Instead, you should cover the ear lightly with a dressing. For minor cuts or wounds to the external ear, apply a cravat bandage as follows: (1) Place the middle of the bandage over the ear (Figure 3- 31A). (2) Cross the ends, wrap them in opposite directions around the head, and tie them (Figures 3-31B and 3-31C). Figure 3-31. Applying cravat bandage to ear (Illustrated A—C). (3) If possible, place some dressing material between the back of the ear and the side of the head to avoid crushing the ear against the head with the bandage. e. Nose Injuries. Nose injuries generally produce bleeding. The bleeding may be controlled by placing an ice pack (if available) over the nose, or pinching the nostrils together. The bleeding may also be controlled by placing torn gauze (rolled) between the upper teeth and the lip. CAUTION DO NOT attempt to remove objects inhaled into the nose. An untrained person who removes such an object could worsen the casualty’s condition and cause permanent injury. f. Jaw Injuries. Before applying a bandage to a casualty’s jaw, remove all loose or free-floating foreign material from the casualty’s mouth. 3-28 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) If the casualty is unconscious, check for obstructions in the airway and remove if possible. If there is profuse bleeding in the oral cavity, the cavity may require loose packing with soft bandaging material (for example: Kerlix™ gauze) prior to applying a bandage. Care should be taken to avoid occluding the airway. When applying the bandage, allow the jaw enough freedom to permit passage of air and drainage from the mouth. (1) Apply bandages attached to field first aid dressing to the jaw. After dressing the wound, apply the bandages using the same technique illustrated in Figure 3-32A—C. NOTE The dressing and bandaging procedure outlined for the jaw serves a twofold purpose. In addition to stopping the bleeding and protecting the wound, it also immobilizes a fractured jaw. (2) Apply a cravat bandage to the jaw. (a) Place the bandage under the chin and pull its ends upward. Adjust the bandage to make one end longer than the other (Figure 3-32A). (b) Take the longer end over the top of the head to meet the short end at the temple and cross the ends over (Figure 3-32B). (c) Take the ends in opposite directions to the other side of the head and tie them over the part of the bandage that was applied first (Figure 3-32C). Figure 3-32. Applying a cravat bandage to jaw (Illustrated A—C). 3-29 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) NOTE The cravat bandage technique is used to immobilize a fractured jaw or to maintain a sterile dressing that does not have tail bandages attached. 3-11. Shoulder Bandage a. To apply bandages attached to the field first aid dressing— (1) Take one bandage across the chest and the other across the back and under the arm opposite the injured shoulder. (2) Tie the ends with a square knot (Figure 3-33). Figure 3-33. Shoulder bandage. b. To apply a cravat bandage to the shoulder or armpit— (1) Make an extended cravat bandage by using two triangular bandages (Figure 3-34A); place the end of the first triangular bandage along the base of the second one (Figure 3-34B). (2) Fold the two bandages into a single extended bandage (Figure 3-34C). (3) Fold the extended bandage into a single cravat bandage (Figure 3-34D). After folding, secure the thicker part (overlap) with two or more safety pins (Figure 3-34E). (4) Place the middle of the cravat bandage under the armpit so that the front end is longer than the back end and safety pins are on the outside (Figure 3-34F). 3-30 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (5) Cross the ends on top of the shoulder (Figure 3-34G). (6) Take one of the bandage ends across the back and under the arm on the opposite side and the other end across the chest. Tie the ends (Figure 3-34H). Figure 3-34. Extended cravat bandage applied to shoulder or armpit (Illustrated A—H). 3-31 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Be sure to place sufficient wadding in the armpit. DO NOT tie the cravat bandage too tightly. Avoid compressing the major blood vessels in the armpit. 3-12. Elbow Bandage To apply a cravat bandage to the elbow— a. Bend the arm at the elbow and place the middle of the cravat at the point of the elbow bringing the ends upward (Figure 3-35A). b. Bring the ends across, extending both downward (Figure 3- 35B). c. Take both ends around the arm and tie them with a square knot at the front of the elbow (Figure 3-35C). Figure 3-35. Elbow bandage (Illustrated A—C). CAUTION If an elbow fracture is suspected, DO NOT bend the elbow; bandage it in the position found. 3-13. Hand Bandage a. To apply a triangular bandage to the hand— (1) Place the hand in the middle of the triangular bandage with the wrist at the base of the bandage (Figure 3-36A). Ensure that the fingers are separated with absorbent material to prevent chafing and irritation of the skin. 3-32 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) (2) Place the apex over the fingers and tuck any excess material into the pleats on each side of the hand (Figure 3-36B). (3) Cross the ends on top of the hand, take them around the wrist, and tie them (Figures 3-36C—E) with a square knot. Figure 3-36. Triangular bandage applied to hand (Illustrated A—E). b. To apply a cravat bandage to the palm of the hand— (1) Lay the middle of the cravat over the palm of the hand with the ends hanging down on each side (Figure 3-37A). (2) Take the end of the cravat at the little finger across the back of the hand, extending it upward over the base of the thumb; then bring it downward across the palm (Figure 3-37B). (3) Take the thumb end across the back of the hand, over the palm, and through the hollow between the thumb and palm (Figure 3- 37C). (4) Take the ends to the back of the hand and cross them; then bring them up over the wrist and cross them again (Figure 3-37D). (5) Bring both ends down and tie them with a square knot on top of the wrist (Figure 3-37E—F). 3-33 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-37. Cravat bandage applied to palm of hand (Illustrated A—F). 3-14. Leg (Upper and Lower) Bandage To apply a cravat bandage to the leg— a. Place the center of the cravat over the dressing (Figure 3- 38A). b. Take one end around and up the leg in a spiral motion and the other end around and down the leg in a spiral motion, overlapping part of each preceding turn (Figure 3-38B). c. Bring both ends together and tie them (Figure 3-38C) with a square knot. Figure 3-38. Cravat bandage applied to leg (Illustrated A—C). 3-34 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) 3-15. Knee Bandage To apply a cravat bandage to the knee as illustrated in Figure 3-39, use the same technique applied in bandaging the elbow. CAUTION If a fracture of the kneecap is suspected, DO NOT bend the knee; bandage it in the position found. Figure 3-39. Cravat bandage applied to knee (Illustrated A—C). 3-16. Foot Bandage To apply a triangular bandage to the foot— a. Place the foot in the middle of the triangular bandage with the heel well forward of the base (Figure 3-40A). Ensure that the toes are separated by absorbent material to prevent chafing and irritation of the skin. b. Place the apex over the top of the foot and tuck any excess material into the pleats on each side of the foot (Figure 3-40B). c. Cross the ends on top of the foot, take them around the ankle, and tie them at the front of the ankle (Figure 3-40C—E). 3-35 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) Figure 3-40. Triangular bandage applied to foot (Illustrated A—E). 4-1 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) CHAPTER 4 FIRST AID FOR FRACTURES 4-1. General A fracture is any break in the continuity of a bone. Fractures can cause total disability or in some cases death by severing vital organs and/or arteries. On the other hand, they can most often be treated so there is a complete recovery. The potential for recovery depends greatly upon the first aid the individual receives before he is moved. First aid includes immobilizing the fractured part in addition to applying lifesaving measures when necessary. The basic splinting principle is to immobilize the joints above and below the fracture. 4-2. Kinds of Fractures Figure 4-1 depicts types of fractures. Figure 4-1. Types of fractures (Illustrated A—C). a. Closed Fracture (Figure 4-1A). A closed fracture is a broken bone that does not break the overlying skin. The tissue beneath the skin may be damaged. A dislocation is when a joint, such as a knee, ankle, or shoulder, is not in the proper position. A sprain is when the connecting tissues of the joints have been torn. Dislocations and sprains (swelling, possible deformity, and discoloration) should be treated as closed fractures. b. Open Fracture (Figure 4-1B and 4-1C). An open fracture is a broken bone that breaks (pierces) the overlying skin. The broken bone may 4-2 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) come through the skin or a missile such as a bullet or shell fragment may go through the flesh and break the bone. NOTE An open fracture is contaminated and subject to infection. 4-3. Signs and Symptoms of Fractures Indications of a fracture are deformity, tenderness, swelling, pain, inability to move the injured part, protruding bone, bleeding, or discolored skin at the injury site. A sharp pain when the service member attempts to move the part is also a sign of a fracture. WARNING DO NOT encourage the casualty to move the injured part in order to identify a fracture since such movement could cause further damage to surrounding tissues and promote shock. If you are not sure whether a bone is fractured, care for the injury as a fracture. At the site of the fracture, the bone ends are sharp and could cause vessel (artery and/or vein) damage. 4-4. Purposes of Immobilizing Fractures A fracture is immobilized to prevent the sharp edges of the bone from moving and cutting tissue, muscle, blood vessels, and nerves. This reduces pain and helps prevent or control shock. In a closed fracture, immobilization keeps bone fragments from causing an open wound, which can become contaminated and subject to infection. 4-5. Splints, Padding, Bandages, Slings, and Swathes a. Splints. Splints may be improvised from such items as boards, poles, sticks, tree limbs, or cardboard. If nothing is available for a splint, the chest wall can be used to immobilize a fractured arm and the uninjured leg can be used to immobilize (to some extent) the fractured leg. b. Padding. Padding may be improvised from such items as a jacket, blanket, poncho, shelter half, or leafy vegetation. 4-3 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) c. Bandages. Bandages may be improvised from belts, rifle slings, kerchiefs, or strips torn from clothing or blankets. Narrow materials such as wire or cord should not be used to secure a splint in place. The application of wire and/or narrow material to an extremity could cause tissue damage and a tourniquet effect. d. Slings. A sling is a bandage suspended from the neck to support an upper extremity. If a bandage is not available, a sling can be improvised by using the tail of a coat or shirt or pieces of cloth torn from such items as clothing and blankets. The triangular bandage is ideal for this purpose. Remember that the casualty’s hand should be higher than his elbow, and the fingers should be showing at all times. The sling should be applied so that the supporting pressure is on the uninjured side. e. Swathes. Swathes are any bands (pieces of cloth or load bearing equipment [LBE]) that are used to further immobilize a splinted fracture. Triangular and cravat bandages are often used and are called swathe bandages. The purpose of the swathe is to immobilize; therefore, the swathe bandage is placed above and/or below the fracture—not over it. 4-6. Procedures for Splinting Suspected Fractures Before beginning first aid procedures for a fracture, gather whatever splinting materials are available. Ensure that splints are long enough to immobilize the joint above and below the suspected fracture. If possible, use at least four ties (two above and two below the fracture) to secure the splints. The ties should be square knots and should be tied away from the body on the splint. Distal pulses of the affected extremity should be checked before and after the application of the splint. a. Evaluate the Casualty. Be prepared to perform any necessary lifesaving measures. Monitor the casualty for development of conditions that may require you to perform necessary lifesaving measures. WARNING Unless there is immediate life-threatening danger, such as a fire or an explosion, DO NOT move the casualty with a suspected back or neck injury. Improper movement may cause permanent paralysis or death. 4-4 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) WARNING In a chemical environment, DO NOT remove any protective clothing. Apply the dressings and splints over the garments. b. Locate the Site of the Suspected Fracture. (1) Ask the casualty for the location of the injury. • Does he have any pain? • Where is it tender? • Can he move the extremity? NOTE With the presence of an obvious deformity, do not make the casualty move extremity. (2) Look for an unnatural position of the extremity. (3) Look for a bone sticking out (protruding). c. Prepare the Casualty for Splinting the Suspected Fracture. (1) Reassure the casualty. Tell him that you will be providing first aid for him and that medical help is on the way. (2) Loosen any tight or binding clothing. (3) Remove all jewelry from the injured part and place it in the casualty’s pocket. Tell the casualty you are doing this because if the jewelry is not removed and swelling occurs later, he may not be able to get it off and further bodily injury could result. (4) Boots should not be removed from the casualty unless they are needed to stabilize a neck injury or there is actual bleeding from the foot. d. Gather Splinting Materials. If standard splinting materials (splints, padding, and cravats) are not available, gather improvised materials. If splinting material is not available and the suspected fracture CANNOT be 4-5 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) splinted, then swathes, or a combination of swathes and slings can be used to immobilize the extremity. e. Pad the Splints. Pad the splints where they touch any bony part of the body, such as the elbow, wrist, knee, ankle, crotch, or armpit areas. Padding prevents excessive pressure on the area, which could lead to circulation problems. f. Check the Circulation Below the Site of the Injury. (1) Note any pale, white, or bluish-gray color of the skin, which may indicate impaired circulation. Circulation can also be checked by depressing the toe or fingernail beds and observing how quickly the color returns. A slower return of color to the injured side when compared with the uninjured side indicates a problem with circulation. The fingernail bed is the method to use to check the circulation in a dark-skinned casualty. (2) Check the temperature of the injured extremity. Use your hand to compare the temperature of the injured side with the uninjured side. The body area below the injury may be colder to the touch indicating poor circulation. (3) Question the casualty about the presence of numbness, tightness, cold, or tingling sensations. WARNING Casualties with fractures of the extremities may show impaired circulation, such as numbness, tingling, cold or pale to bluish skin tone. These casualties should be evacuated by medical personnel and treated as soon as possible. Prompt medical treatment may prevent possible loss of the limb. WARNING If it is an open fracture and the bone is protruding from the skin, DO NOT ATTEMPT TO PUSH THE BONE BACK UNDER THE SKIN. Apply a field dressing over the wound to protect the area. 4-6 FM 4-25.11/NTRP 4-02.1/AFMAN 44-163(I) g. Apply the Splint in Place. (1) Splint the fracture in the position found. DO NOT attempt to reposition or straighten the injury. If it is an open fracture, stop the bleeding and protect the wound. Cover all wounds with field dressings before applying a splint. Remember to use the casualty’s field dressing, not your own. (2) Place one splint on each side of the fracture. Make sure that the splints reach, if possible, beyond the joints above and below the fracture. (3) Tie the splints. Secure each splint in place above and below the fracture site with improvised (or actual) cravats. Improvised cravats, such as strips of cloth, belts, or whatever else you have, may be used. With minimal motion to the injured areas, place and tie the splints with the bandages. Push cravats through and under the natural body curvatures, and then gently position improvised cravats and tie in place. Use square knots. Tie all knots on the splint away from the casualty (Figure 4-2). DO NOT tie cravats directly over the suspected fracture site. Figure 4-2. Square knots tied away from casualty. h. Check the Splint for Tightness. (1) CHECK to be sure that bandages are tight enough to securely hold splinting materials in place, but not so tight that circulation is impaired. (2) RECHECK the circulation after application of the splint. Che
