Which is a recommended technique for controlling bleeding in TCCC?

Using a tourniquet is a recommended technique for controlling bleeding in Tactical Combat Casualty Care (TCCC). A tourniquet is specifically designed to stop severe bleeding from an extremity by occluding blood flow, and it can be a critical intervention for life-threatening hemorrhages.

In combat situations, where rapid and effective bleeding control is essential, the application of a tourniquet can significantly increase the chances of survival for a casualty. It is especially crucial for injuries that are not amenable to other forms of bleeding control, such as direct pressure or wound packing.

Moreover, the use of a tourniquet is well-supported by military guidelines and best practices, emphasizing its importance in emergency medical response scenarios. This technique allows medical providers to stabilize the patient for further evaluation and treatment while minimizing the risk of exsanguination.

Other methods listed, such as applying heat packs, massaging the wound area, or using cold compresses, are not effective for controlling severe bleeding and could potentially cause more harm than good in a combat situation.
