Body temperature drops to below 95? F (35? C). All major organ systems are affected, including decreased blood flow through the kidneys and brain. Most victims are the elderly who are unable to keep warm in winter. Body temperature is deliberately reduced during some surgical procedures.
Causes of Hypothermia
Prolonged exposure to cold temperatures, especially outdoors with a high wind-chill factor, can lead to hypothermia. A near drowning episode, particularly in cold water, can produce severe hypothermia. Even exposure to near normal temperatures can lead to hypothermia, if person is ill or debilitated.
Signs and Symptoms of Hypothermia
Early symptoms of hypothermia include poor muscle coordination, mental confusion, shivering and low body temperature (below 95° F or 35° C). The pulse slows and the person becomes drowsy and lethargic. As the condition worsens, the muscles may become rigid. If the temperature drops to a range from 77° F to 84° F (25° C to 28.9°C), the fingers, toes and nail beds appear purple and the person becomes unconscious.
