What is a "tourniquet"?

A tourniquet is a tight band or device placed around a limb to stop bleeding or control circulation during medical emergencies or procedures. It is usually made of elastic material or a simple strap that can be tightened to restrict blood flow temporarily. Tourniquets are used to prevent excessive bleeding from wounds or to make it easier for healthcare providers to insert needles for medical treatments. Proper use of a tourniquet is crucial for managing emergencies safely and effectively.
