A tourniquet should be applied when direct pressure fails to control severe bleeding. This is a critical intervention in situations where a traumatic injury is causing life-threatening hemorrhage, particularly in an extremity. The application of a tourniquet can significantly reduce the risk of exsanguination and can be life-saving.

In the context of severe bleeding, a tourniquet acts by occluding blood flow to the affected area, effectively stopping blood loss. It is essential to assess the situation thoroughly; if direct pressure on the wound does not yield results, then a tourniquet becomes the next appropriate intervention to stabilize the patient.

While mild bleeding can often be managed with basic measures such as elevation and direct pressure, a tourniquet is not indicated in those cases. Similarly, not all open wounds require a tourniquet, as many can be managed through simple first aid techniques. Administering pain relief medications has no direct relation to the application of a tourniquet and does not influence the need for its use in managing bleeding. For these reasons, the application of a tourniquet is specifically reserved for instances of uncontrolled, severe hemorrhage when other methods have failed.
