What is the most essential treatment task during Care Under Fire?

During Care Under Fire, the most critical treatment task is to control massive bleeding with a limb tourniquet. This phase occurs while the casualty is still in a potentially dangerous environment, such as in the line of fire, where the risk to the rescuer and the casualty remains high.

Controlling massive hemorrhage is paramount because uncontrolled bleeding is the leading cause of preventable death in trauma situations. As such, the application of a tourniquet is a rapid and effective intervention to stop life-threatening bleeding from an extremity. In this phase, time is of the essence, and managing significant blood loss can dramatically improve the casualty’s chance of survival until further medical care can be administered.

While establishing a safe zone is important, it cannot occur effectively until the immediate threat is neutralized. Airway management is vital but is secondary to controlling hemorrhage in the context of the active threat. Transporting the casualty to safety is also essential, yet it must follow the immediate control of any hemorrhaging wounds to maximize survival chances. Thus, the priority in Care Under Fire remains to address massive bleeding first.
