Where should a tourniquet be placed in relation to a wound?

The appropriate placement of a tourniquet is critical for effectively controlling bleeding, especially in traumatic injuries. It should be positioned 5 cm proximal to the wound. This means that the tourniquet should be applied above the site of injury, on the limb closer to the torso, rather than directly at the wound site.

By placing the tourniquet proximal to the wound, it allows for the occlusion of blood flow to the injured area without interfering with the wound itself. Applying it next to the wound or on the wound could lead to inadequate pressure and fail to effectively control the bleeding. Additionally, being too close to the wound might also exacerbate any potential tissue damage or impede the assessment of the injury. Thus, the recommended 5 cm proximal placement is a widely accepted practice in emergency medical situations to ensure maximum effectiveness in bleeding control while minimizing complications.
