Tourniquet Tightness: Balancing Bleeding Control and Limb Safety

A tourniquet must be tight enough to stop bleeding but not so tight that it cuts off arterial supply.

If too tight: Tissue damage, nerve damage, limb loss.

Monitoring: Loosen every 15–20 minutes to restore blood flow. If bleeding doesn't stop in 2–3 minutes, loosen and reapply.
