Explanation:
Detailed explanation-1: -Hypovolemic shock is due to a critical loss in the effective circulating blood volume with systemic hypoperfusion. If left untreated, hypovolemic shock can lead to ischemic injury of vital organs, leading to multi-system organ failure and death.
Detailed explanation-2: -The 1974 American National Red Cross Advanced First Aid and Emergency Care book summarized the practice and its physiologic basis succinctly: “Elevation uses the force of gravity to help reduce the blood pressure in the injured area and thus aid in slowing down the blood loss through the wound opening” [1].
