A tourniquet is a constricting or compressing device used to control venous and arterial circulation to an extremity for a period of time. Pressure is applied circumferentially upon the skin and underlying tissues of a limb; this pressure is transferred to the walls of vessels, causing them to become temporarily occluded.[LINK: http://tourniquets.org] Tourniquets.org Surgical tourniquets enable surgeons to work in a bloodless operative field. Emergency tourniquets are used in emergency bleeding control to prevent severe blood loss from limb trauma.
