Why should applying a tourniquet only be considered as a last resort?

Applying a tourniquet should be considered a last resort because it can cause significant tissue damage and loss of limb function if used improperly or for extended periods. It can also lead to complications such as nerve damage or ischemia. Additionally, inappropriate application may prevent necessary medical intervention and delay appropriate treatment. Therefore, tourniquets should only be employed when other methods of controlling bleeding have failed and in life-threatening situations.
