What is the primary purpose of using a tourniquet in medical emergencies?

The primary purpose of using a tourniquet in medical emergencies is to control severe bleeding. When a person suffers from a traumatic injury that results in significant blood loss, particularly in a limb, a tourniquet can be applied to constrict the blood vessels and restrict blood flow to that area. This is critical in preventing excessive blood loss, which can lead to shock or even death if not managed promptly.

The proper use of a tourniquet is essential in situations where direct pressure and other methods of controlling bleeding are insufficient. It is a life-saving intervention that allows emergency responders to stabilize the patient until they can receive more definitive medical care.

While stabilization of fractures, providing oxygen, and treating shock are important aspects of emergency care, they do not specifically address the immediate need to control life-threatening hemorrhage as effectively as a tourniquet does.
