A shirt, socks, etc., can all work. Use only your hands if no cloth is available. If possible, elevate the wound above the heart. This is not as good as direct pressure in most cases. Using a pressure point stops all circulation to that part of the body.
Direct pressure stops circulation only at the wound.
When using pressure points, you should first use direct pressure over the wound. Add a pressure point only after you have used direct pressure and bleeding has not stopped. After bleeding has stopped, release the pressure point and maintain direct pressure on the wound. A tourniquet is not recommended to stop bleeding. Clean small wounds with hand soap and water.
