A tourniquet is a medical device used to completely stop the flow of blood to a limb. It consists of a band that is tightened around the limb above the injury, occluding the blood vessels. Tourniquets are typically applied in cases of severe, life-threatening bleeding where direct pressure alone is insufficient to control hemorrhage. Their use is generally reserved for battlefield injuries or severe trauma situations due to the potential for serious complications if not applied correctly or for too long.

The primary purpose of a tourniquet is to save a life by preventing excessive blood loss. They work by compressing both arteries and veins. While effective for hemorrhage control, prolonged application can lead to nerve damage, tissue death, and even limb amputation. Therefore, tourniquets should only be applied by trained individuals and removed as soon as possible by qualified medical personnel. The development of modern, commercially produced tourniquets has improved their ease of use and effectiveness compared to improvised methods.

Common types of tourniquets include the Combat Application Tourniquet (CAT) and the Special Operations Forces Tactical Tourniquet (SOFTT). These are designed to be applied quickly with one hand. Proper training in the application and management of tourniquets is crucial to maximize their benefit while minimizing risks. Signs that a tourniquet is correctly applied include the cessation of bleeding and a lack of pulse below the application site.
