Definition: Accidental hypothermia is an unintentional core body temperature of < 35°C when heat loss to surroundings is greater than heat generation Most frequent cause is environmental exposure Patient with impaired thermoregulation can develop hypothermia in relatively warm environments Elderly, underlying illness, trauma, intoxication, or malnutrition (Brown 2012)

Definition: A life-threatening emergency in which there is a failure of the body’s thermoregulatory mechanisms to handle extrinsic and intrinsic heat. The failure of thermoregulation leads to multi-system organ dysfunction characterized by alteration of neurologic function. Unlike in fever, hyperthermia is not caused by endogenous pyrogens that change the thermoregulation set point in the brain. […]
