In the case of arterial bleeding in the extremities, there is usually active bleeding from the wound, or a burst of bleeding. First, if the injured vessel is relatively small, local pressure dressing can be applied, which can usually stop the bleeding. Secondly, if the pressure dressing is unsuccessful or the vessel is relatively large, the proximal limb of the wound must be given with a bandage or a tourniquet plate, thus blocking the arterial blood flow at the proximal end of the wound can achieve the effect of hemostasis. But this proximal binding method, must be relaxed once in half an hour or an hour or so, to avoid ischemic necrosis due to long-term ischemia of the distal limb. Once again if there is an injury to the organ, resulting in arterial bleeding, this is a very dangerous situation. It should be sent to the hospital immediately for preoperative preparation and emergency surgical treatment.
