How to Stop Severe Bleeding: First Aid & Stop the Bleed Techniques

Severe bleeding — also called hemorrhage — is one of the leading preventable causes of death from trauma. A person can bleed to death in as little as 5 minutes from a major wound. The American Heart Association First Aid guidelines and the national Stop the Bleed campaign both emphasize that bystanders who know how to control bleeding can save lives before emergency medical services arrive.

Recognizing life-threatening bleeding: Blood that is spurting or pulsing from a wound, blood that is pooling on the ground, clothing that is soaked with blood, bandages that are soaking through, or a victim who is confused, pale, or losing consciousness — all indicate a life-threatening hemorrhage that requires immediate action.

Step 1: Ensure your own safety and call 911. Put on gloves if available. If the bleeding is from a violent incident, make sure the scene is safe before approaching. Direct someone to call 911 while you begin treatment.

Step 2: Apply direct pressure. Place a clean cloth, gauze, or even a piece of clothing directly over the wound and press down firmly with both hands. Do not lift the cloth to check the wound — this disrupts clot formation. If blood soaks through, add more material on top and continue pressing. Maintain constant, firm pressure for at least 10 minutes.

Step 3: Pack the wound if direct pressure alone is not controlling the bleeding. For deep wounds, the Stop the Bleed protocol recommends packing gauze or clean cloth directly into the wound cavity, pushing it as deep as possible, and then applying firm pressure on top. This technique is especially effective for wounds in areas where a tourniquet cannot be applied, such as the neck, armpit, or groin.

Step 4: Apply a tourniquet for life-threatening limb bleeding. If direct pressure and wound packing cannot control bleeding from an arm or leg, a tourniquet is the next step. Place the tourniquet 2 to 3 inches above the wound (never directly on a joint). Tighten until the bleeding stops. Note the time of application and communicate this to EMS. Commercial tourniquets are preferred, but an improvised tourniquet using a belt, scarf, or strip of fabric with a windlass (a stick or pen to twist and tighten) can work in an emergency.

What NOT to do: Do not remove objects embedded in a wound — stabilize them in place. Do not apply a tourniquet to the neck or torso. Do not use a tourniquet that is too narrow (like a wire or string) as it can cause tissue damage. And do not hesitate to act because you are afraid of causing pain — the victim's life depends on stopping the blood loss. Our First Aid and Stop the Bleed courses in Tallahassee provide hands-on training with tourniquets, wound packing simulators, and realistic scenarios so you are prepared to act decisively when seconds count.
