A tourniquet is a device used to apply pressure to a limb or extremity in order to stop the flow of blood. It is typically used in emergency situations to control life-threatening external bleeding. Tourniquets can be made from a stick and a rope, but commercial and professional tourniquets are more effective and safer to use. There are three types of tourniquets: surgical tourniquets, emergency tourniquets, and rehabilitation tourniquets.
To apply a tourniquet correctly, the wound should be exposed, and firm, direct pressure should be applied to the wound using gauze, clean cloth, or any other material that can slow or stop the hemorrhage. If the pressure does not stop the bleeding, and the dressing becomes soaked with blood, a tourniquet should be applied at least 2-3 inches from the wound. The tourniquet should be manually tightened and secured over clothing, and the patients blood pressure should be measured to determine the correct model.
Tourniquets can potentially save lives in situations such as motor vehicle or motorcycle crashes, farm and industrial incidents, or household misadventures. It is important to ensure your own safety first before applying a tourniquet and to call 911 immediately or direct someone else to do so. Tourniquets are typically included in most trauma first aid kits and can also be purchased online from a medical goods store.
