Within what time limit should bleeding be stopped with a tourniquet?

The appropriate time frame to effectively apply a tourniquet and stop bleeding is ideally within one minute. Rapid application is crucial because severe bleeding can lead to life-threatening conditions in a short period of time. When trauma occurs, especially in combat situations, the priority is to control hemorrhage to maximize the chances of survival. It is essential to apply the tourniquet high and tight on the limb and to ensure that it completely occludes blood flow.

This rapid response can drastically reduce the risk of shock and other complications resulting from significant blood loss. Delaying beyond this timeframe may result in increased risk for the patient, as severe hemorrhage can result in irreversible damage and potential death within minutes if not addressed urgently. Therefore, the one-minute guideline stresses the need for quick action in imposing a tourniquet when faced with a life-threatening bleeding situation.
