Severe bleeding can become fatal in a matter of minutes, and the first person on scene is often a bystander or coworker, not a medical professional. This guide gives you the order of actions for how to treat severe bleeding until emergency responders take over: call for help, expose the wound, apply direct pressure, use a tourniquet when needed, pack the wound, and monitor for shock. You need no equipment to begin, though a first aid kit with gloves, gauze, and a commercial tourniquet makes each step easier. This guide is educational and does not replace hands-on training, which is the best way to build the skill.

Step 1: Make the Scene Safe and Call 911

Look around before you move toward the injured person. Traffic, broken glass, running machinery, unstable structures, and an aggressive person who caused the injury are all reasons to stop and reassess. If the scene is not safe, stay back, call for help, and move the person only if you can do so without putting yourself at risk. A second victim helps no one.

Call 911, or your local emergency number, right away. If other people are present, point to one person and say, "You, call 911 and put it on speaker." Naming a specific person works better than a general shout because everyone else assumes someone else is calling. Speakerphone matters because you will need both hands for the wound.

Protect yourself from blood if you can:

Put on gloves from a first aid kit. Nitrile gloves are a common choice, and they are suitable for people with latex allergies.
If you have no gloves, use a barrier such as a plastic bag, a thick cloth, or a clean layer of clothing between your skin and the blood.
Do not delay pressure on a heavily bleeding wound while hunting for gloves. A person's life matters more than a few seconds of ideal protection, and you can wash thoroughly afterward.

Stay on the line once the call connects. Dispatchers are trained to coach callers through bleeding control, and they can tell you when responders are close and relay what you report. Do not hang up until the dispatcher says you can.

Step 2: Expose the Wound and Identify Life-Threatening Bleeding

You cannot control bleeding you cannot see. Remove clothing from the injured area, or cut it away with shears or a knife if it is stuck or tight. Pull aside belts, sleeves, and pant legs until you can see exactly where the blood is coming from. Soaked fabric can hide the real source.

Several signs tell you the bleeding is life-threatening:

Blood spurting or pulsing from the wound
Blood pooling on the ground or soaking through clothing
Bleeding that does not slow or stop when you press on it
Clothing or bandages that are quickly saturated
A severed or partly severed limb

Check for bleeding you might miss. Blood runs downward and collects under a person, so look at the back of the arm or leg, behind the knee, under the torso, and beneath the head and hair. Run a gloved hand along the limb or body and check your glove for blood. A person with several wounds needs the most serious one controlled first.

This is the decision point. A minor cut or scrape oozes slowly, stops with brief pressure, and can be rinsed with clean water and covered with a bandage. If what you see matches any of the signs above, go straight to Step 3 without stopping to clean the wound.

Step 3: Apply Firm, Direct Pressure

Direct pressure means pushing straight down on the bleeding site to squeeze the damaged vessels closed and give a clot the chance to form. It is the first and most important physical treatment for almost every bleeding wound.

Place a clean cloth, sterile gauze, or your gloved hand directly over the wound and press hard. It should be firmer than feels comfortable. For a deep wound or a large limb, stack your hands, lock your elbows, and lean your body weight into it. If the person is on the ground, kneeling beside them lets you use your weight rather than just arm strength.

A few rules keep the pressure effective:

Do not lift the cloth to check. Each peek tears away forming clots and restarts the bleeding.
If blood soaks through, add more material on top. Leave the first layer in place and keep pressing.
Hold pressure continuously until emergency responders arrive and take over. Do not stop after a minute or two to see whether it has worked.

The most common mistake is pressing too lightly or for too short a time. Tired arms and the sight of blood make people ease off. If you feel your arms giving out, ask a bystander to place their hands on top of yours or to take over, and swap without releasing the pressure.

Resist the urge to reach for a tourniquet as a first reflex. If firm direct pressure controls the bleeding, keep using it. A tourniquet is for situations where pressure fails or cannot be maintained, which is the next step.

Step 4: Apply a Tourniquet for Limb Bleeding That Pressure Cannot Control

A tourniquet is a band that squeezes an arm or leg tightly enough to stop blood flow to the wound below it. Use one when bleeding from a limb is life-threatening and direct pressure is not controlling it, or when you cannot stay with the person or keep pressure on, for example because you must help several injured people or the scene becomes unsafe.

A commercial tourniquet, designed for this purpose, is far more reliable than an improvised one. To apply it:

Place it on the limb 2 to 3 inches above the wound, between the wound and the heart. If the wound is at or just below a joint such as the elbow or knee, place it above the joint. Never place it over a joint.
Pull the strap tight and twist the windlass rod (or use the device's tightening mechanism) until the bleeding stops completely.
Secure the rod in its clip or holder so it cannot unwind.
Write down the time you applied it, on the device's tag if it has one, or on the person's skin or forehead if you have nothing else.

Expect the person to be in significant pain. That is normal and does not mean you have done it wrong. A tourniquet that is not tight enough can be worse than none, because it can block the veins while arterial blood keeps flowing in. If bleeding continues, tighten further. If it still does not stop, place a second tourniquet directly above the first.

Once a tourniquet is on, do not loosen or remove it. Leave that decision to medical professionals. Many people fear that a tourniquet will always cost the person a limb, but the Stop the Bleed program, which draws on military and civilian trauma experience, teaches tourniquets as a lifesaving tool for severe limb bleeding. Check the current Stop the Bleed guidance for the exact wording of this point.

Stop the Bleed training teaches this skill hands-on, and practicing with a real device is worth far more than reading about it. Best Choice CPR can also serve as a source of first aid training for individuals and workplaces.

Step 5: Pack the Wound for Bleeding in Areas Where a Tourniquet Will Not Work

Some bleeding cannot be controlled with a tourniquet because the wound is on the neck, in the armpit, or in the groin, where there is no limb section to squeeze. These junctional areas call for wound packing: filling the wound with absorbent material to press directly on the bleeding vessel from inside.

Gauze made for this purpose is best, and hemostatic gauze, which is treated with an agent that promotes clotting, is better still. If you have none, clean cloth will do. To pack a wound:

Push the gauze or cloth firmly into the wound with your gloved fingers, aiming at the source of the bleeding. Keep feeding in more material until the cavity is full.
Press down hard over the packed wound with both hands.
Hold the pressure for at least 3 minutes, or until responders arrive and take over.

Packing is painful, and the person may cry out or struggle. Stay calm, explain what you are doing, and keep going, because the bleeding must be stopped.

There are limits. Do not pack wounds in the chest or abdomen, since packing there can cause more harm. Do not pack a wound that has an object embedded in it. Leave the object in place, stabilize it with bulky dressings so it cannot move, and apply pressure around it rather than on it.

Guidance on packing duration and technique is updated from time to time. Check the current American College of Surgeons Stop the Bleed program materials, and take a hands-on course to learn the technique on a training model.

Step 6: Position the Person and Watch for Shock

Shock is a life-threatening condition in which the body is not getting enough blood flow to its organs, and heavy blood loss is a common cause. Even when you have stopped the bleeding, the person can still slide into shock, so keep watching.

Have the person lie down and stay still. If you do not suspect an injury to the head, neck, back, or legs, you can raise their legs slightly. Otherwise, leave them flat. Moving someone with a possible spinal injury can make things worse.

Blood loss lowers body temperature, so cover the person with a blanket, coat, or whatever is available, and put a layer between them and cold ground. Do not give them food or drink, even if they ask, because they may need surgery and may vomit.

Signs that the person is going into shock include:

Pale, cool, clammy skin
A fast pulse
Rapid breathing
Confusion or anxiety
Drowsiness or fading responsiveness

Keep talking to the person and tell the dispatcher about any change. If they become unresponsive and are not breathing normally, begin CPR and use an AED if one is available, following the dispatcher's instructions. Bleeding control and CPR are separate skills, and a person who has lost a lot of blood may need both. Training in CPR and AED use prepares you for that moment.

Step 7: Hand Off to Responders and Follow Up

When EMS arrives, give a brief, clear report. Tell them what happened, when it happened, where on the body the injury is, how long you have been applying pressure, and the time the tourniquet went on, if you used one. Those details guide their next decisions.

Leave all dressings and tourniquets exactly as they are. Do not remove packed gauze or loosen a tourniquet to show the wound. Let the professionals take over, and answer their questions.

Then look after yourself. Wash your hands and any skin that touched blood with soap and water. If blood got into a cut, your eyes, your mouth, or other exposed skin, tell a supervisor or see a healthcare provider promptly, as follow-up may be recommended. Dispose of used gloves and soiled materials safely.

Workplace safety coordinators have additional tasks after the incident:

Document what happened, who responded, and the times involved, following your organization's reporting process.
Restock the bleeding control kit, replacing used gloves, gauze, and tourniquets.
Offer a debrief. Responders often feel shaken afterward, and a short conversation helps them process the event and identify what worked and what to improve.

Keep the Skills Ready Before You Need Them

Review these steps regularly, and check that your kits contain gloves, gauze, and tourniquets that are in date. Reading a guide gives you the sequence, but a hands-on first aid or bleeding control course makes the actions feel automatic when adrenaline is high and someone is bleeding in front of you.

Don't wait until an emergency happens. Equip yourself with life-saving CPR skills that could make all the difference when seconds count. Register for a certification class today and gain the confidence to respond when someone needs help most.
