Tourniquet Placement Rule?

• A. 1-2 inches above the wound
• B. 4 inches above the wound
• C. 2-3 inches above the wound, not over joint
• D. Over the wound

Answer: (C)

When a tourniquet is used, the goal is to cut off arterial blood flow to the wound by applying pressure on soft tissue a short distance above the injury. The best guideline is to place the tourniquet about 2-3 inches above the wound, and not over a joint. This position sits on firm, pliable tissue that can transmit the pressure effectively to the artery supplying the injured area, ensuring reliable occlusion. Placing it too close to the wound (about 1-2 inches) risks incomplete arterial compression because the wound margins or damaged tissue can interfere with occlusion. Placing it too far away (like 4 inches above) may move the compression point away from the bleeding source and reduce effectiveness. Avoiding placement over a joint is important because joints have varying contours and movement; a tourniquet over a joint can slip or fail to seal properly, compromising arterial blockage. The 2-3 inch range provides a practical balance across different limb sizes, maximizing the chance of stopping the bleed quickly.
