What measure provides the best chance to reverse the hypothermic process when treating hypothermia?

Active management is the best measure to reverse the hypothermic process when treating hypothermia. This approach involves using direct methods to warm the body, such as administering warm fluids, using heating pads, or providing warm, humidified oxygen. These techniques increase the body temperature more effectively than passive measures or merely relying on warm clothing.

While passive management allows the body's heat to be retained by minimizing exposure to cold, it does not actively increase the core temperature. Utilizing warm clothing alone, though helpful, is not sufficient for severe hypothermia and does not provide the aggressive intervention needed to reverse the condition. Immediate transport to a medical facility is crucial for further treatment, but relying solely on transport without direct intervention will not rectify hypothermia in transit. Therefore, active management is essential for rapid correction of hypothermia and improving patient outcomes.
