hypothermia (redirected from accidental hypothermia)

hypothermia

Abnormally low body temperature, with slowing of physiological activity. It is artificially induced (usually with ice baths) for certain surgical procedures and cancer treatments. Accidental hypothermia can result from falling into cold water or overexposure in cold weather. Underlying conditions such as cerebrovascular disease or intoxication increase the risk from exposure. Hypothermia is serious when body temperature is below 95 °F (35 °C) and an emergency below 90 °F (32.2 °C), at which point shivering stops. Pulse, respiration, and blood pressure are depressed. Even when the victim appears dead, revival may be possible with very gradual passive rewarming (e.g., with blankets). See also frostbite.
