How long can a tourniquet remain applied?

The correct duration for which a tourniquet can remain applied is typically 30-60 seconds. This time frame is crucial because prolonged application of a tourniquet can lead to tissue damage and necrosis due to inadequate blood flow. During this period, the tourniquet is effective in controlling significant bleeding by occluding arterial blood flow.

If a tourniquet is applied for longer than 60 seconds, the risk of serious complications, such as muscle and nerve damage, increases substantially. Medical professionals are trained to use tourniquets judiciously, applying them only when absolutely necessary and for the shortest time possible while still achieving hemostasis. This understanding is integral to the safe and effective management of traumatic injuries in both pre-hospital settings and clinical environments.
