How to apply a tourniquet?

Posted: 2022-11-29 17:08

In the battlefield, tourniquet is one of the most widely used first aid products.

The purpose of using a tourniquet is to limit bleeding from an injured limb to avoid life-threatening injuries. It is a temporary first aid treatment that, if done correctly, will slow the bleeding or stop it long enough for emergency responders to arrive.

The first we have to learn is what a tourniquet consists of. The most widely used tourniquet recently is the spinning-on nylon tourniquet. The two most important parts of this kind of tourniquet are the nylon belt and the rod for spinning, made of nylon or metal. For life-threatening bleeding from the arm or leg, a tourniquet is recommended.


1. If possible, let the injured person lie down to more easily find the bleeding wound. The tourniquet should not be in direct contact with the skin, but should be tied around the arm or leg through the clothing.

Wrap the tourniquet around the bleeding arm or leg about 2 to 3 inches above the bleeding wound. Be sure not to place the tourniquet over the joint. If necessary, place it over the joint.

2. Tighten the tourniquet by pulling on the free end of the tourniquet to make it as tight as possible and secure the tourniquet by adhering the free end with Velcro webbing.

3. Twist or spin the rod until it could not turn or the bleeding stops. Then place the rod on the plastic buckle to secure it so that the tourniquet remains tight and does not require constant pressure on the wound.

4. Write down the time of using the tourniquet on the white part of the nylon belt as a reference, which is good for the medical staff to follow up the treatment and can also avoid the wound necrosis caused by too long tightening time.

The above is the correct use of tourniquet steps.
