This guide details the proper application of a Combat Application Tourniquet (CAT) for severe extremity bleeding. It emphasizes correct placement 2-3 inches above the injury, ensuring extreme tightness to occlude blood flow, and securing the windlass and strap to maintain pressure. The importance of time recording and avoiding joints is also highlighted.

Quick Summary

To effectively use a Combat Application Tourniquet (CAT), place it 2-3 inches above the injury, ensuring no joints are covered. Tighten it until all slack is removed, so you cannot fit three fingers underneath. Turn the windlass until bleeding stops, then secure it and record the application time.

Frequently Asked Questions

What are the key indicators that a tourniquet is needed?

A tourniquet is necessary for major bleeding on an extremity. Signs include a large amount of blood pooling on the ground, blood spurting, or clothing becoming heavily saturated with blood.

Where should a tourniquet be placed on an injured limb?

A tourniquet should be placed 2-3 inches above the injury site. It is crucial to avoid placing it directly over a joint like the elbow or knee to ensure effectiveness and prevent further damage.

How tight does a tourniquet need to be to work effectively?

The tourniquet must be tightened to remove all slack, making it snug enough that you cannot slip three fingers between the band and the limb. This ensures sufficient pressure to stop arterial bleeding.

Why is it important to record the time of tourniquet application?

Recording the application time is vital for medical professionals to know how long the tourniquet has been in place. This information helps them assess potential risks and plan treatment, as prolonged application can lead to nerve and tissue damage.

Can a tourniquet be applied over clothing?

Yes, while applying a tourniquet directly to the skin is ideal, it can be applied over clothing if necessary. However, it's important to remove any obstructions like knives or wallets from pockets that could interfere with placement or pressure.
