where should you tie the tourniquet in order to control life threatening bleeding from a limb
Emergency bleeding control Improvised tourniquets, in addition to creating potential problems for the ongoing medical management of the patient, usually fail to achieve force enough to adequately compress the arteries of the limb. As a result, they not only fail to stop arterial bleeding, but may actually increase bleeding by impairing venous bloodflow.[16]
Pulse Pressure waves generated by the heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave.
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
