What is a C.A.T. Tourniquet？
The CAT Tourniquet (Combat Application Tourniquet) is a small and lightweight arterial tourniquet that completely occludes blood flow in an extremity. Used for the treatment of life-threatening bleeding, the CAT Tourniquet uses a Self-Adhering Band and a Friction Adaptor Buckle to fit a wide range of extremities combined with a one-handed windlass system. The windlass uses a free moving internal band to provide true circumferential pressure to an extremity. The windlass is then locked in place; this requires only one hand, with the Windlass Clip. The CAT Tourniquet also has a Hook-and-Loop Windlass Strap for further securing of the windlass during patient transport.
The Combat Application Tournquet (C.A.T) is a proven tried and true tourniquet which should be a part of every medical kit designed to combat bleeding wounds. The C.A.T excels in single handed use when compared to altnertives and is both lightweight and compact. The durable windlass system is constructed with a polymer handle which helps reduce weight, and tightens down the patented free-moving internal band. This free moving band applies true circumferential pressure to the extremity.

How effective is a CAT tourniquet?
A study published in the Journal of Trauma and Acute Care Surgery found that the CAT tourniquet was 100% effective in stopping arterial blood flow when applied correctly. Additionally, the U.S. Army Institute of Surgical Research has credited the use of tourniquets like the CAT with saving lives during the wars in Iraq and Afghanistan.
However, the effectiveness of a CAT tourniquet also depends on the user’s training and ability to apply it properly. Incorrect application can result in continued bleeding, or cause injury to the patient. Therefore, proper training on the use of a tourniquet like the CAT is very important.
How long can you leave a CAT tourniquet on?
As for how long you can leave a CAT tourniquet on, the general guideline is that it should not be left on for more than two hours. The two-hour rule is based on the risk of complications from prolonged tourniquet use. These complications can include nerve damage, muscle damage, and tissue death.
