What is the maximum recommended time for leaving a tourniquet applied?

1 hour
2 hours
3 hours
4 hours

The correct answer is: 2 hours

The maximum recommended time for leaving a tourniquet applied is generally around two hours. This recommendation is based on the need to balance controlling severe bleeding while minimizing the risk of permanent tissue damage or loss of circulation to the extremities. If a tourniquet is left in place for an extended period, especially beyond the two-hour mark, the risk of tissue necrosis increases significantly due to the lack of blood flow. Limiting the application time to two hours allows for effective control of bleeding while also providing a window in which medical intervention can occur, ideally to either alleviate the tourniquet or treat the injury at the hospital level. While one, three, and four-hour durations might seem to provide some flexibility, the consensus in emergency medicine emphasizes the importance of the two-hour minimum to prevent long-term damage to the affected area. Moreover, if a tourniquet is needed, it typically indicates a serious situation where prompt medical treatment is crucial, reinforcing the need for timely intervention.
