What is the purpose of the turniquey?

A tourniquet is a medical device used to control bleeding by applying pressure to a limb or extremity. Its primary purpose is to restrict blood flow to a wound, helping to prevent excessive blood loss in emergencies. Tourniquets are commonly used in trauma situations, particularly in cases of severe injuries, to stabilize the patient until further medical treatment can be administered. Proper application is crucial, as improper use can lead to complications, including tissue damage.
