What is the longest you can wear tourniquet?

A tourniquet should generally not be left on for more than 1 to 2 hours, as prolonged application can lead to tissue damage due to restricted blood flow. In some cases, if a tourniquet is applied properly and monitored, it may be tolerated for up to 6 hours, but this increases the risk of complications. It's crucial to seek medical attention as soon as possible when a tourniquet is used. Always prioritize removing it under medical supervision to minimize risks.
