Tourniquet Application

What Is Tourniquet Application?

Tourniquet application is the rapid emergency placement of a commercial constricting band (such as the CAT or SOFT-T) high and tight on an injured limb (2-3 inches proximal to bleeding site or high on the extremity) to occlude arterial blood flow and stop life-threatening hemorrhage.

Why Tourniquet Application Matters on the Fireground

Arterial limb bleeding can cause fatal exsanguination in under 3 minutes. Applying a tourniquet immediately saves lives in severe trauma, traumatic amputations, and mass casualty events before shock becomes irreversible.

Relevant NFPA Standards

• NREMT Standards: National Registry of Emergency Medical Technicians Practice Standards
• NFPA 455: Standard for Emergency Medical Services (EMS)

Field Procedures & Tactical Steps

1. Identify life-threatening extremity arterial bleeding (spurting blood, rapidly expanding pool).
2. Place tourniquet high and tight on the injured limb (or 2-3 inches above bleeding site, not over joint).
3. Pull self-adhering band tight to eliminate all slack before twisting windlass.
4. Twist windlass rod until bright red arterial bleeding stops and distal pulse is no longer palpable.
5. Lock windlass in clip, secure strap, and write application time (T = HH:MM) on tourniquet time strap and patient forehead.

Common Context & Application

Executed on severe trauma calls, gunshots, stabbings, industrial amputations, and active shooter responses under TCCC/TECC guidelines.
