In Care Under Fire, why is it crucial to stop life-threatening external hemorrhage?

In Care Under Fire, it is crucial to stop life-threatening external hemorrhage because the application of a tourniquet can be anatomically effective in significantly controlling severe bleeding. This intervention is critical during the high-risk phase of care when both the casualty and the provider are exposed to potential threats. Stopping the hemorrhage promptly helps stabilize the casualty’s condition, increasing the chances of survival before they can receive further treatment at a safer location. The ability to effectively apply a tourniquet is a vital skill, as it enables the provider to address the most immediate and life-threatening concern—the loss of blood—while preparing for subsequent steps in care and evacuation. This direct focus on hemorrhage control often outweighs other considerations in this chaotic and dangerous environment.
