What is a tourniquet, how is it applied and what types are there?

In emergency situations, a tourniquet can mean the difference between life and death. Knowing what it is, how to use it correctly, and when to apply it is essential for controlling severe bleeding. In this article, we explain everything you need to know about tourniquets and show you the best options available at SERMILITAR.

What is a tourniquet?

A tourniquet is a device used to stop blood flow in a limb when there is life-threatening bleeding in an arm or leg. Its function is to compress the blood vessels to prevent excessive blood loss, which can be vital in emergency situations such as accidents, gunshot wounds, or explosions.

Types of tourniquets

There are different types of tourniquets, each designed for specific situations and with various methods of application. The most commonly used are:

1. CAT Tourniquet (Combat Application Tourniquet)

It is the most popular among military personnel and emergency teams. It fastens with a strap and a windlass rod for quick and effective hemorrhage control. To apply it, follow the manufacturer’s instructions for the model being used.

The U.S. Army officially adopted the C-A-T in 2005, and since then it has become the standard for hemorrhage control in tactical and emergency settings, being used by military forces, emergency teams, and police worldwide.

2. SOFTT-W Tourniquet

Similar to the CAT, but with a wider band and a more robust closure system, ideal for use in extreme conditions. This was developed by the American company Tactical Medical Solutions (TacMed Solutions); incorporating a wider strap helps reduce tissue damage and improve effectiveness in hemorrhage control.

The SOFTT-W has been adopted by various military units and security forces, standing out for its high durability, quick-release aluminum alloy buckle, and ease of use with one hand.

3. SICH Tourniquet

Developed in the heat of the Ukraine war following the Russian invasion of its territory, the SICH tourniquet is, so to speak, an evolution of the CAT, featuring a lever made of more durable aluminum and an adjustment system that allows us to secure the tourniquet comfortably and safely with one hand.

This tourniquet has been widely used on the battlefield and is an ideal option for military personnel and law enforcement agencies.

4. Improvised tourniquets

A commercial tourniquet designed to control severe bleeding is preferable to an improvised one. Do not assume that an elastic belt, such as the Hemantas by Pentagon, offers the same effectiveness as a tourniquet designed for this purpose.

At SERMILITAR you can find different models of tourniquets and accessories such as tourniquet pouches for safe transport.

How to Apply a Tourniquet Correctly?

Improper use of a tourniquet can cause tissue and nerve damage. Follow the manufacturer’s instructions and the training you have received; seek urgent medical assistance:

1. Identify the hemorrhage: Identify life-threatening bleeding in an arm or leg. Direct pressure can be used while a tourniquet is being obtained or if one is not available.

2. Place the tourniquet: Apply it about 5-7 cm above the wound, avoiding placing it over a joint.

3. Adjust and tighten: Make sure it is tightened properly. If the bleeding does not stop, tighten it further.

4. Secure the tourniquet: Use the tourniquet locking system to prevent it from loosening.

5. Record the time: Note when the tourniquet was applied and inform the emergency services. Seek urgent medical assistance. Do not loosen or remove it; this must be done by a healthcare professional.

When should you use a tourniquet?

A tourniquet is used to control life-threatening bleeding in the arms or legs. The following injuries can cause this type of bleeding:

• Stab or gunshot wounds.

• Traffic accidents with partial or total amputations.

• Explosions or injuries from heavy machinery.
