Why This Matters

Uncontrolled bleeding from a limb injury can cause death in as little as 3 minutes. A tourniquet applied in the first 60 seconds stops that bleeding completely and keeps the patient alive until definitive medical care is available. The CAT tourniquet is the most proven life-saving device in modern emergency medicine.

Product Description

The Combat Application Tourniquet (CAT) is the most widely used and rigorously tested tourniquet in military and emergency medical service history. Its windlass mechanism applies circumferential pressure to completely occlude arterial blood flow in a single-handed application within seconds. It works on both arms and legs and secures via a time-stamp buckle to track application time. Every trauma kit, bug-out bag, and vehicle kit should have at least one CAT tourniquet.

Real Use Case

A chainsaw accident severs an artery in your forearm while clearing storm debris. Roads are blocked and emergency services are 40 minutes away. You apply your CAT tourniquet one-handed above the wound, crank the windlass until bleeding stops, and note the time on the time tag. When EMS arrives 35 minutes later you are conscious, stable, and alive.
