The below image talks about signs of ongoing life-threatening bleeding that may not have been noted or appropriately addressed in Care Under Fire. These include pulsatile blood, steady bleeding from the wound, blood pooling on the ground or soaking overlying clothing or bandages, or blood flowing at the site of a traumatic amputation of an arm or leg.
Any obvious ongoing life-threatening bleeding should be addressed immediately.
In combat casualties, early control of significant external hemorrhage is the most important intervention. Hemorrhage remains the predominant cause of preventable death in combat fatalities.
Early tourniquet use prevents limb exsanguination and saves lives. Nonindicated tourniquet placement is common (even when CUF is included as an indication), and morbidity is uncommon when tourniquet use is relatively brief.
