Is Elevation Effective for Controlling Bleeding in the Field?

Using Elevation to Control Bleeding

Elevation is commonly used in conjunction with a tourniquet or direct pressure to control bleeding from limbs. To elevate an injured limb, have the individual sit or lie down with the injured limb above the level of their heart. This elevation should be at least 12-18 inches above the level of the heart for effective blood flow reduction. For example, if the individual is injured in a prone position, elevate the injured limb to a supine position.

Applying Tourniquet with Elevation

When using elevation in conjunction with a tourniquet, apply the tourniquet as close to the wound as possible to minimize the risk of tissue damage. The tourniquet should be tightened in a slow and controlled manner, and the individual should be checked for signs of circulatory compromise, such as numbness, tingling, or paleness. The tourniquet should not be left in place for more than 2 hours without relief, as this can cause permanent nerve damage.

Direct Pressure with Elevation

If a tourniquet is not available, direct pressure should be applied to the wound using a clean cloth or gauze. The pressure should be firm, but not too tight, and should be maintained for at least 5-7 minutes to allow the bleeding to slow. Elevation should be maintained during this time to further reduce blood flow to the area.
