How far above the wound should a tourniquet typically be placed?

• A. 1 inch
• B. 5 inches
• C. 2 inches above the wound
• D. 2-3 inches above the wound

Answer: (D)

The goal is to stop arterial inflow by placing the tourniquet on the limb proximal to the wound, with enough distance to ensure the device compresses the artery rather than just surrounding tissue. The typical distance is about 2-3 inches above the wound (roughly 5–7.5 cm). This placement keeps the tourniquet over firm tissue and away from the injury, maximizing occlusion effectiveness. Placing it too close, like around 1 inch, may not reliably stop bleeding, while placing it much farther away, such as 5 inches, isn’t necessary and can prolong ischemia. 2-3 inches above the wound strikes a balance for effective arterial control.
