Hypothermia is defined as a core body temperature below 35°C. Mechanisms of heat loss include radiation, evaporation, convection, and conduction. As temperature decreases, physiological responses include vasoconstriction, shivering and changes in basal metabolic rate. Clinical features range from vague symptoms in mild hypothermia to loss of consciousness and absent reflexes in severe cases. Management focuses on passive or active rewarming depending on severity. Outcomes are worse with prehospital cardiac arrest, hemodynamic instability, and lab abnormalities indicating organ damage.
