Question: 1 / 400

How far above a wound should a tourniquet be applied?

1-2 inches

2-3 inches

A tourniquet should be applied 2-3 inches above the wound to effectively control arterial bleeding while minimizing the risk of damage to surrounding tissues. This distance allows for adequate pressure to occlude blood flow without being so far from the injury that it becomes less effective. Applying it too close to the wound may allow blood to continue flowing, while applying it too far away could result in unnecessary pressure on unaffected areas, potentially causing tissue damage.

In trauma situations, it's crucial for first responders to establish a balance between sufficient distance for effective bleeding control and proximity to the injury. Therefore, 2-3 inches is the optimal range that trauma nurses and emergency personnel typically adhere to in practice guidelines. This recommendation aligns with established protocols for the application of tourniquets in emergency care settings, ensuring better outcomes for patients with significant hemorrhage.
