A tourniquet may be used to control life-threatening bleeding to a limb but may also cause permanent irreparable damage. Use a tourniquet only as a last resort when all other methods of controlling bleeding have failed.
A tourniquet must be a minimum of 5cm wide and is not to be applied over the wound or a joint. This should be applied tight enough to stop circulation to the injured limb and not be removed until the casualty receives specialist care. Write down the time the tourniquet was applied and pass on to emergency personnel.
Pressure Point Bleeding Control
If normal methods of controlling a bleed fail, and a tourniquet or suitable improvised materials are not available, as a last resort you may apply pressure on the main artery above the wound, this will reduce the blood supply to the affected limb.
