What do I do if someone is bleeding heavily?

Call 911, then press hard on the wound and don’t let up. Use a tourniquet for life-threatening bleeding from an arm or leg if you have one.

Call 911

Do this now

  1. Call 911 or have someone call. Put the phone on speaker.
  2. Press hard on the wound with a clean cloth or your hands. Lean your body weight into it.
  3. Keep pressing without stopping. If blood soaks through, add more cloth on top — don’t lift the first layer.
  4. For an arm or leg that won’t stop bleeding, use a tourniquet 2 to 3 inches above the wound (not on a joint). Tighten until the bleeding stops and note the time.
  5. Keep the person lying down and warm until help arrives.
Call 911 if:
  • Blood is spurting, pouring, or pooling, or soaks through cloth quickly
  • Bleeding doesn’t slow after several minutes of firm pressure
  • The wound is deep, from a serious injury, or on the neck, chest, belly, or groin
  • The person seems confused, very sleepy, pale, cold, or clammy

Deep wounds

If the wound is deep, like in the thigh, armpit, or groin, pack it: stuff clean cloth or gauze firmly into the wound, then press hard with both hands.

Tourniquets

Use a manufactured tourniquet if one is available. It will hurt — that is normal. Don’t loosen or remove it once it’s on; medical professionals will do that. If you don’t have a real tourniquet, keep pressing hard on the wound. Mayo Clinic advises against makeshift tourniquets like belts or scarves.

Avoid

  • Don’t remove an object stuck in a wound. Press around it, not on it.
  • Don’t keep lifting the cloth to check the wound.
