Quick Answer
When using a tourniquet in a remote area, apply it to the affected limb as close to the wound as possible, and set the tourniquet to a pressure of 250-300 mmHg to control bleeding. This should be done as a last resort and with proper training. A tourniquet should be left in place for at least 2 hours before removal.
Choosing the Right Tourniquet
When selecting a tourniquet for use in a remote area, consider the terrain, weather, and available resources. The CAT (Combat Application Tourniquet) and SOF-T (Special Operations Forces Tactical Tourniquet) are popular options due to their ease of use and reliability. These tourniquets are typically pre-packaged with a windlass system and can be applied with one hand.
Applying the Tourniquet
To apply a tourniquet in a remote area, first, dress the wound with a clean cloth or gauze to prevent further contamination. Next, locate the femoral or axillary artery, depending on the location of the wound, and place the tourniquet around the limb as close to the wound as possible. Tighten the windlass until the bleeding stops, then secure the tourniquet with the provided clip or strap. Set the tourniquet to a pressure of 250-300 mmHg to control bleeding.
Monitoring the Patient
After applying the tourniquet, monitor the patient for signs of inadequate circulation, such as pale or cool skin, decreased pulse, or numbness. If these symptoms occur, loosen the tourniquet by one-quarter to one-half turn to relieve pressure. If the bleeding does not stop or recurs, consider applying a second tourniquet or seeking medical attention.
