Similarly, you can't bind your limbs with a tourniquet for a long time unless you have to do arterial ligation. Generally, when stopping bleeding, first try the direct pressing method, then use the pressing point method until you use the method of keeping pressing the wound directly. If the wound is located at the end of the limb, the wound can be raised.
