Using cleangauze or a clean white cloth, apply pressure to the wound, for several minutes. If the injury is on one of the extremities; IE: arm, hand, leg or foot, try to elevate it to a position that is higher than the heart, while maintaining pressure on the site of the bleeding. Do NOT remove the gauze/cloth to check if bleeding has stopped. If blood comes through the gauze or cloth, do NOT remove it. Apply more gauze/cloth on top of the first and apply pressure again. It is very important that you do not remove the gauze/cloths. In fact, they must be secured to the wound. When you don't see the blood coming through the gauze/cloths, use another roll of gauze or long strips of cloth to wrap around the area, to secure the gauze/cloths to the wound. Depending on the severity of the bleeding/blood lost, either take the injured to receive professional medical attention, or call an ambulance to take the injured to the hospital.
