Which tourniquet is the preferred tourniquet in Tactical Combat Casualty Care (TCCC)?

The Combat Action Tourniquet (CAT) is preferred in Tactical Combat Casualty Care (TCCC) because it is specifically designed for use in combat scenarios, offering several key advantages. The CAT is easy to use and can be applied quickly, which is critical in high-stress environments where every second counts. Its design allows for rapid tightening and secure placement—important factors for effectively controlling severe hemorrhage from limb injuries.

One feature that makes the CAT particularly effective is its windlass system, which allows for the application of increased pressure against the limb to occlude arterial blood flow. This capability is crucial for preventing exsanguination until definitive medical care can be provided. Additionally, the CAT is lightweight and can be used with one hand, making it practical for use in the chaotic environment often encountered during combat.

Furthermore, extensive training and field use have validated the efficacy of the CAT, leading to its endorsement by multiple military and emergency medical organizations. In contrast, other tourniquets might not offer the same ease of application or effectiveness in urgent situations, making the CAT the standard choice in TCCC.
