An esmark compression bandage is used prior to turning the tourniquet on before surgery. Once it is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet, it is removed so the extremity can be prepped. - Provides consistent compression to extremities for exsanguination prior to surgery. Delivers 400% elongation for maximum compression. Made of a poly-isopropolene compound with low powder content. Individually wrapped and sterile. For use in surgical procedures, especially joint replacement. 4 inches x 3 yards.
