What is the primary purpose of using a tourniquet?

The primary purpose of using a tourniquet is to control severe bleeding from a traumatic injury. When faced with a situation where a patient is experiencing significant hemorrhage, particularly from a limb, a tourniquet can effectively occlude blood flow in order to minimize blood loss and prevent shock. This mechanism is vital in emergency medical situations where rapid intervention is necessary to preserve life and maintain hemodynamic stability.

Tourniquets are often employed as a last resort after other means of bleeding control, such as direct pressure and elevation, have proven ineffective. They create a tight constriction around the limb to stop arterial blood flow, which is crucial in life-threatening scenarios. Understanding the application and importance of a tourniquet is essential for paramedics, allowing them to provide timely and effective care to patients with traumatic injuries.
