What type of patients qualify for tourniquet application?

The application of a tourniquet is specifically indicated for patients who are experiencing uncontrolled extremity hemorrhage. This condition occurs when bleeding from a limb is difficult to control using direct pressure or other traditional methods. In such cases, a tourniquet can be an essential life-saving intervention, as it effectively halts blood flow to an injured area, significantly reducing the risk of severe blood loss and potential death from exsanguination.

Tourniquets are primarily used in scenarios where a patient's bleeding is life-threatening and cannot be managed through standard first-aid techniques. The urgency of effectively addressing uncontrolled bleeding is critical, as rapid intervention can considerably improve survival outcomes. In situations where bleeding is not exceeding normal limits or is controlled, alternative methods such as direct pressure are generally preferable, making those patients unsuitable for tourniquet application.
