What should responders do if they encounter a patient with uncontrolled external bleeding?

When responders encounter a patient with uncontrolled external bleeding, the first and foremost action is to apply direct pressure to the wound to help control the bleeding. This is crucial as excessive blood loss can lead to shock and potentially fatal complications. If direct pressure does not effectively stem the flow of blood, utilizing a tourniquet becomes necessary, particularly in cases of severe limb injuries where arterial bleeding occurs. The application of a tourniquet can significantly reduce blood loss and buy precious time before the patient receives advanced medical care.

The decision to apply pressure and use a tourniquet is rooted in the principles of first aid and trauma management. It prioritizes the immediate treatment of life-threatening conditions and aims to stabilize the patient until further medical intervention can be provided. Therefore, taking swift action to control bleeding is critical in these scenarios.
