Chapter 3
Stopping the Bleed
Printed in full here from the book.
Stop the Loss
Recognize life-threatening bleeding, choose direct pressure, a manufactured tourniquet, or wound packing, and hold the intervention until emergency care takes over.
- Find a Safe Place Severe bleeding can kill quickly. Before you touch the patient, look for a safe place to work. Move away from a falling tree, boat traffic, live wires, fire, or rising water. Put on gloves or use a clean barrier if you have one. If the bleeding is life-threatening, send someone to call 911 while you start care. If you are alone, call 911 on speaker as soon as you can and keep the phone with you.
- Recognize Severe Bleeding Look for blood that is flowing continuously or spurting, a large open wound, an amputation, or a patient who is pale, cold, dizzy, weak, confused, or less responsive. Treat those signs as an emergency. Arterial blood may be bright and pulsing. Venous blood may be dark and steady. Capillary blood usually oozes. Do not wait to name the vessel. Stop any significant loss. Check for more than one wound, but control the life threat first.
- Reassure the Patient Use these actions only for an emergency while 911 or local emergency care is being activated. Reassure the patient. Tell them what you are doing and that the pain from a tourniquet is expected when it is saving a life. Keep the patient from getting cold, watch breathing and responsiveness, and be ready to give new information to the dispatcher.
You need: Gloves or Barrier (Nitrile gloves or a clean barrier)
Check it. Pass: you find a safe place, use a barrier, and call 911 while you start care. Fail: you work under a falling limb or in rising water.
Field check
- I look for blood flowing continuously or spurting.
- I put on gloves or use a clean barrier.
- I call 911 while I start care.
Safety. Call 911 for life-threatening bleeding, shock signs, an amputation, or bleeding you cannot control. Do not remove an embedded object.
Choose the Method
For life-threatening bleeding, call 911, choose pressure, packing, or a manufactured tourniquet, and do not stop the intervention until help takes over.
- Start With Pressure Direct pressure is the starting move for an exposed wound. Find the source, place gauze or a clean cloth over it, and press hard with a steady hand. Do not lift the dressing to peek. If blood comes through, add one pad on top and press harder; do not stack pads. If a life-threatening bleed is on an arm or leg, use a manufactured tourniquet as soon as it is available. A tourniquet is not a last resort. It is a primary tool for a limb bleed that can kill.
- Packing Beyond Reach A tourniquet cannot reach the scalp, neck, shoulder, groin, or back. Pack those junctional or cavity wounds with hemostatic gauze if available, or plain gauze or clean cloth, and then apply direct pressure. Do not pack an eye, chest, or abdomen. Do not pull out an embedded object. Press around it and build dressings around it.
- Keep Watching Once a tourniquet controls a life-threatening limb bleed, do not loosen or remove it in the field. Write the application time where rescuers can see it. If the first tourniquet does not stop the bleeding, apply a second manufactured tourniquet above it, closer to the heart, following its instructions. Keep reassessing the patient. A dressing that worked can slip, a tourniquet can need tightening, and shock can worsen.
You need: Gauze or Clean Cloth (Sterile gauze or a clean cloth)
Check it. Pass: you press first and use a tourniquet for a limb bleed that can kill. Fail: you treat a tourniquet as a last resort.
Field check
- I place gauze or a clean cloth over the wound.
- I keep the first layer in place.
- I use a manufactured tourniquet for a life-threatening limb bleed.
- I do not pack an eye, chest, or abdomen.
Safety. Use a tourniquet and wound packing within your training. If you are not trained, hold firm direct pressure until help arrives. Do not pull out an embedded object. Press around it and build dressings around it.
Pressure and Tourniquet
Hold without interruption until the bleeding stops, a tourniquet is tight and working, another rescuer takes over, you are too exhausted to continue, or the scene becomes unsafe.
- Hold Pressure Use a firm, flat surface under the injured limb when you can do so without moving the patient into danger. Cover the wound with gauze or a clean cloth and press directly over the source. Hold without interruption until the bleeding stops, a tourniquet is tight and working, another rescuer takes over, you are too exhausted to continue, or the scene becomes unsafe. Elevating a limb may be used with pressure, but it never replaces pressure for severe bleeding.
- Check Circulation When bleeding stops on a limb without a tourniquet, secure the single dressing with a roller bandage. It must be firm but must not cut off circulation below the injury. Check the skin beyond the dressing for color, temperature, feeling, and numbness or tingling. If bleeding returns, remove the bandage but leave the original dressing in place and press by hand again. For major bleeding, call 911 even if the flow stops. The patient needs emergency evaluation and monitoring for shock.
- Tourniquet Use Use a manufactured tourniquet for life-threatening bleeding from an arm or leg, a traumatic amputation, several patients needing care, or a scene where pressure cannot be maintained safely. Place it directly on skin two to three inches above the wound, between the wound and the heart. Never put it over a joint or on top of the wound.
Field check
- I hold pressure without interruption until help takes over.
- I use elevation only with pressure.
- I check the skin beyond the dressing for color and feeling.
- I place a tourniquet directly on skin 2 to 3 inches above the wound.
- I note the time.
Safety. Elevating a limb may be used with pressure, but it never replaces pressure for severe bleeding.
- Windlass Device Follow the instructions for the exact device. For a windlass device, pull the strap as tight as possible, secure the buckle, twist the windlass until the bleeding stops, and secure the windlass in its clip. The loss of the distal pulse is a useful training check, but the field goal is control of bleeding.
- Second Tourniquet and Time If blood still flows, tighten the device and apply a second manufactured tourniquet above the first. Note the time. Do not cover the tourniquet with a dressing or clothing. Do not loosen it because the patient says it hurts. Call 911 and tell the dispatcher that a tourniquet is in place.
Field check
- I hold pressure without interruption until help takes over.
- I use elevation only with pressure.
- I check the skin beyond the dressing for color and feeling.
- I place a tourniquet directly on skin 2 to 3 inches above the wound.
- I note the time.
Safety. Elevating a limb may be used with pressure, but it never replaces pressure for severe bleeding.
Packing and Shock
Packing is for a deep, life-threatening wound in the scalp, neck, shoulder, groin, or back, and for a limb bleed when no tourniquet is available or a tourniquet cannot control it.
- Packing Beyond Reach Packing is for a deep, life-threatening wound in the scalp, neck, shoulder, groin, or back, and for a limb bleed when no tourniquet is available or a tourniquet cannot control it. If the wound is on the neck, protect the airway and press carefully so you do not block breathing. Call 911.
- Pack the Cavity Expose the wound enough to find the cavity. Push the end of hemostatic gauze or plain gauze directly to the deepest part of the bleeding source. Feed the material into the cavity one layer at a time. Pack firmly until the cavity is full. Then place a pad over the packed wound and hold hard, steady pressure without lifting to check. The patient must be watched for changing breathing, responsiveness, skin color, and shock.
- Use Clean Material If the kit is empty, a clean shirt, bandanna, or clean cloth can provide pressure or packing. A gloved hand is better than hesitation. Improvised tourniquets are less reliable than manufactured devices and are not the first choice. Never use loose dirt, moss from the bank, or an unclean natural material in an open wound. Keep pressure in place until another rescuer takes over, bleeding stops, you cannot continue, or the scene becomes unsafe.
- Signs of Shock Keep the patient warm without overheating. Do not give food or drink to a patient who is confused, vomiting, or likely to need urgent procedures. Stay with the patient and watch breathing and responsiveness. Look for pale, gray, cool, moist skin, a rapid weak heartbeat, rapid breathing, thirst, dizziness, or altered responsiveness. These signs can mean shock. Call 911 or update the dispatcher if they appear or worsen.
Check it. Pass: you pack the deepest point layer by layer and watch for shock. Fail: you pack the chest, abdomen, or eye.
Field check
- I pack only a deep wound where a tourniquet cannot reach.
- I push gauze to the deepest part and pack firmly.
- I use clean cloth, never dirt or moss.
- I keep pressure in place until another rescuer takes over.
- I watch for pale, gray, cool, moist skin and a rapid weak heartbeat.
Safety. A stopped bleed is not a finished rescue. Never use loose dirt, moss from the bank, or an unclean natural material in an open wound.
Handover and Tourniquet
Tell rescuers what happened, where the wounds are, what you used, whether bleeding stopped, and the exact tourniquet time.
- Handover to Rescuers Tell rescuers what happened, where the wounds are, what you used, whether bleeding stopped, and the exact tourniquet time. Keep the original dressing and the tourniquet in place. Make the landing or access area safe if help is coming by boat or aircraft, but do not abandon the patient for a better view. In blackwater country, protect the wound from muddy river water and keep the patient on stable ground above the bank. Stay calm, keep pressure honest, and do not let a quiet-looking patient fool you.
- Within Your Training Use a tourniquet and wound packing within your training. If you are not trained, hold firm direct pressure until help arrives.
You need: Windlass Tourniquet (A manufactured windlass tourniquet and its instructions)
Field check
- I tell rescuers what happened, where the wounds are, and what I used.
- I give the exact tourniquet time.
- I protect the wound from muddy river water.
- I keep the patient on stable ground above the bank.
- I keep the original dressing and the tourniquet in place.
Safety. Keep the patient warm, monitor breathing and responsiveness.
- Hemostatic or Plain Gauze Hemostatic gauze or plain gauze for packing
- Pressure Bandage and Marker A pressure bandage, tape, and a marker for the application time
- Crew Field Check Your three-person canoe crew finds a partner collapsed at a landing after a snag. The phone has no signal. Give each crew member a job and name your first message when signal returns.
Field check
- I tell rescuers what happened, where the wounds are, and what I used.
- I give the exact tourniquet time.
- I protect the wound from muddy river water.
- I keep the patient on stable ground above the bank.
- I keep the original dressing and the tourniquet in place.
Safety. Keep the patient warm, monitor breathing and responsiveness.
Direct Pressure
Direct pressure is the starting move for an exposed wound.
- Call and Expose For life-threatening bleeding, call 911 or direct another person to call while you put on a barrier and expose the source.
- Press the Source Place gauze or a clean cloth directly over the wound and press firmly with the patient on a stable surface.
- Hold Without Interruption Keep uninterrupted pressure until bleeding stops, a working tourniquet takes over, another rescuer relieves you, you are exhausted, or the scene becomes unsafe.
- Add Material If blood shows through, leave the first layer in place, add one pad on top, and press harder instead of lifting to look.
- Check Circulation When bleeding is controlled without a tourniquet, secure the single dressing firmly, check circulation beyond it, and keep watching for re-bleeding.
Check it. Pass: pressure stays on the source without peeking, the first dressing remains in place, and the patient is monitored while 911 is activated. Fail: lifting the dressing to check, using elevation alone, or walking away from life-threatening bleeding.
Field check
- I call 911 or direct another person to call while I put on a barrier.
- I press firmly with the patient on a stable surface.
- I keep uninterrupted pressure until bleeding stops.
- I leave the first layer in place and add one pad on top.
- I check circulation beyond the dressing.
Safety. Elevating a limb may be used with pressure, but it never replaces pressure for severe bleeding.
Windlass Tourniquet
Use a manufactured tourniquet for life-threatening bleeding from an arm or leg, a traumatic amputation, several patients needing care, or a scene where pressure cannot be maintained safely.
- Choose the Device For life-threatening arm or leg bleeding, traumatic amputation, multiple patients, or an unsafe pressure position, call 911 and choose a manufactured tourniquet.
- Place Above Wound Place it directly on skin 2 to 3 inches above the wound, between the wound and the heart, never over a joint or the wound.
- Tighten Windlass Pull the strap as tight as possible, secure the buckle, and twist the windlass until bleeding stops.
- Secure and Check Secure the windlass, check that bleeding remains controlled, and apply a second manufactured tourniquet above the first if needed.
- Write the Time Write the application time where rescuers can see it, leave the tourniquet in place, and tell 911 that it is applied.
Check it. Pass: a manufactured device is tight enough to stop life-threatening bleeding, is not over a joint, the time is marked, and it is not loosened. Fail: loose strap, placement on the wound or joint, hidden time, continued bleeding with no correction, or removal before medical care.
Field check
- I place it directly on skin 2 to 3 inches above the wound.
- I never put it over a joint or the wound.
- I pull the strap as tight as possible.
- I apply a second manufactured tourniquet above the first if needed.
- I leave the tourniquet in place.
Safety. Do not loosen or remove a tourniquet in the field.
Junctional Wound Packing
Packing is for a deep, life-threatening wound in the scalp, neck, shoulder, groin, or back, and for a limb bleed when no tourniquet is available or a tourniquet cannot control it.
- Expose the Cavity For life-threatening bleeding in the scalp, neck, shoulder, groin, or back, call 911 and expose the cavity without removing an embedded object.
- Reach the Source Push hemostatic gauze, plain gauze, or clean cloth directly to the deepest part of the wound toward the bleeding source.
- Space Feed the material into the cavity layer by layer and pack firmly until the space is full.
- Hold the Pad Place a pad over the packed wound and hold steady direct pressure without lifting to inspect it.
- Watch the Patient Keep watching breathing, responsiveness, skin condition, and bleeding until another rescuer takes over or emergency care arrives.
Check it. Pass: the material reaches the source, fills the cavity, pressure stays on top, the airway remains open, and 911 is active. Fail: shallow loose packing, blind probing, packing the wrong body area, pulling out an embedded object, or leaving before handover.
Field check
- I pack only a deep wound where a tourniquet cannot reach.
- I push hemostatic gauze directly to the deepest part of the wound.
- I pack firmly until the space is full.
- I hold steady direct pressure without lifting to inspect it.
- I keep watching breathing, responsiveness, skin condition, and bleeding.
Safety. Do not pack the chest, abdomen, or eye.
