Tourniquet

For other uses, see Tourniquet (disambiguation).

A tourniquet is a medical device used to stop the flow of blood to a limb or extremity via the application of localized pressure. It may be used in emergencies, in surgery, or in post-operative rehabilitation.

A simple tourniquet can be made from a stick and a rope, but the use of makeshift tourniquets has been reduced over time due to their ineffectiveness compared to a commercial and professional tourniquet. This may stem the flow of blood, but side effects such as soft tissue damage and nerve damage may occur.
