1. The tourniquet will block the flow of blood. If the strapping time is too long, it will seriously damage the tissue--even leading to limb necrosis.
2, the tourniquet can only be used to bundle the limbs, never bundle the head, neck or trunk.
3, do not cover with other items, do not cover the tourniquet bundled on the limbs. If you have to leave the patient alone in the camp, on his head, use a pen or lipstick to write the time of the strapping and the position of the toolbox.
4. Check the circulation of blood. After the bandage is finished, check the toes or fingers frequently to see if there is a purple spot on the end of the bandage, and whether the body temperature at that place has decreased. If there is such a phenomenon, the tape should be loosened, otherwise the tissue will be necrotic if the time is long.
5. For the same reason, it is not possible to use a tourniquet to bind the limb for a long time, unless it is necessary to do it during the operation of the artery ligation. In general, when hemostasis, try directly on the pressure method, and then use the pressure point method until the method of maintaining direct pressure on the wound is used. If the wound is at the end of the limb, the wound can be raised.
