What is the maximum time a tourniquet should be left on?

The maximum time a tourniquet should be left on is ideally less than two hours if possible because prolonged use of a tourniquet can lead to complications such as irreversible muscle and nerve damage. The goal is to control life-threatening hemorrhage while minimizing the risk of permanent injury. Although a tourniquet can be effective in saving lives, timely medical intervention is crucial for the best outcomes. Keeping the duration under two hours provides a balance between controlling bleeding and safeguarding the body’s tissues. This understanding of the risks associated with longer application times underscores the preference for shorter durations whenever feasible.
