- 5IF A LIMB IS BLEEDING UNCONTROLLABLYIf pressure fails and a tourniquet is available and you know how to use it, apply it above the wound and note the time.
- 6WATCH FOR SHOCKKeep the person lying down and warm with a blanket, and keep talking to them.
DO NOT DO
- DO NOT keep removing dressings to check the wound.
- DO NOT remove an object embedded in the wound — press around it instead.
- DO NOT wash a large deep wound; controlling bleeding comes first.
- DO NOT apply a tourniquet loosely or use thin string or wire.
- DO NOT delay calling 112 while searching for supplies.
WHILE WAITING FOR HELP
- Maintain firm, continuous pressure until the ambulance crew takes over.
- Keep the person lying flat and warm.
- Note the time the tourniquet was applied, if one was used, and tell the crew.
- Do not give food or drink.
WHEN TO ESCALATE
- Unresponsive with abnormal breathing → Cardiac Arrest flow.
- Confusion, grey skin, very fast breathing → tell 112 the person is deteriorating.
AFTERCARE
- All deep or heavily bleeding wounds need medical review, including for tetanus and infection.
- Small wounds: clean with clean running water, cover with a sterile dressing, and watch for infection.
Special cases
Trained responders: wound packing and tourniquets
- PROFESSIONAL-LEVEL INFORMATION — only for people trained in bleeding control.
- For junctional or deep limb wounds, pack the wound with gauze and maintain firm pressure for at least 3 minutes.
- Apply a manufactured tourniquet 5–7 cm above the wound, tighten until bleeding stops, record the time, and never loosen it once applied outside hospital.
Nosebleed
- Sit upright, lean forward and pinch the soft part of the nose for 10 minutes without releasing.
- Seek medical care if bleeding continues beyond 20 minutes or follows a head injury.
