A reduction in the central or core temperature of the body below 36 degrees Celsius. In cardiac surgery, a patient may be made hypothermic, by infusing cold liquids into the circulation and/or packing ice around parts of the body. This is done in order that the flow of blood to the brain and other tissues may be reduced, thus allowing the surgeon to safely repair the heart, without damage occurring in the organs that would otherwise be starved of oxygen. With deep hypothermia, the patient (usually an infant) is intentionally cooled to about 16 to 20 degrees Celsius. This allows surgeons to be able to stop the heart for about 45-60 minutes and to operate without either the heart moving or tubing or blood being in the very small operative field.

Body temperature below normal. Usually due to exposure to cold temperatures, especially after exhausting ready energy supplies. Cf. hyperthermia.

A rapid, progressive mental and physical collapse that accompanies the lowering of body temperature.

When the body temperature drops below 35.5 degrees Celsius (95 degrees Fahrenheit).

A serious physical condition caused by a lowering of the core body temperature. Symptoms include lack of coordination, thickness of speech, irrationality, blueness of skin, dilation of pupils, decrease in heart andrespiratory rate, extreme weakness,and uncontrolled shivering. Victims often become unconscious and sometimes die. First Aid: Quickly strip off wet clothes and surround victim skin-to-skin in a bare-body sandwich; administer hot drink, etc.

excessive loss of body heat caused by exposure to very cold water or other conditions.

Inability to keep warm often caused by cold or wet weather.

is a condition brought on when the body temperature drops to less than 32ºC or 90ºF.

Occurs when the body's core temperature drops too low.

Extreme reduction in body temperature

Hypothermia is a sudden and profound cooling of the temperature in the core of your body to below 35.5 degrees C. This can have a crippling effect to the body. Continued cooling can result in an irregular heartbeat that can lead to death.

A life-threatening condition in which body temperature drops to dangerously low levels.

Serious medical condition when the core body temperature becomes too low. Sometimes referred to as exposure. More information: staying warm

an abnormally low body temperature brought on by staying in cold temperatures for a long period of time; a life-threatening emergency.

A condition characterized by an abnormally low body temperature. One potential cause of hypothermia for women is blood loss during the birthing process.

A condition where the body's core temperature drops to a dangerous level, normally in wet and cold conditions. The victim can become drowsy or disoriented. If not treated quickly, hypothermia can lead to death due to exposure.

excessive reduction in body temperature which can lead to frostbite in limbs and possibly to death.

a victim's core body temperature drops due to heat loss exceeding heat production prevent heat loss by: removing wet clothes getting out of the wind adding insulating layers mild hypothermia: early signs are shivering, slurred speech, and confusion victim can still produce sufficient heat, and should drink lots of water and eat energy rich food abort the trip immediately severe hypothermia: victim is in a stupor or is unconscious and cannot produce sufficient heat victim should not be moved, but given external heat sources to stay alive - extremely difficult in the field prevention: dress warmly eat energy foods and drink lots of water often avoid getting chilled at rest stops avoid becoming exhausted

The condition when you are losing heat from your body faster that your body can produce it. If your body gets too cold important parts like your heart might not work properly.

A generalized cooling that may lower the body temperature below normal..

A life-threatening condition in which the body's warming mechanisms fail to maintain normal body temperature and the entire body cools.

A lowering of body core temperature, caused by losing heat faster than it is produced by the body. Hypothermia is a threat when water temperatures are below sixty degrees Fahrenheit, or air temperatures are below fifty degrees Fahrenheit.

The condition of reduced body temperature, which can result in death.

a core body temperature below the lower limit of normal

The dangerous lowering of core body temperature. Frequently a threat to paddlers due to cold-water immersion.

The deterioration in one's mental and physical condition brought on by a rapid lowering of human body temperature. Hypothermia can be fatal.

A potentially dangerous condition in which the body temperature falls to below 96° F (35° C). It is usually the result of prolonged exposure to cold. Symptoms include shallow respiration and a faint heart rate resulting in increased palor and the appearance of death. Treatment includes a slow warming of the body and hospitalization to treat any metabolic abnormalities that may result. The term is also used to describe a procedure in which the body temperature is deliberately and carefully reduced with cooling mattresses or ice in preparation for some surgical procedures.

Abnormally low body temperature. Someone who falls asleep in a snowbank may become hypothermic. Hypothermia is intentionally produced to slow the metabolism during some types of surgery.

A procedure that lowers a patient's body temperature during surgery. It stops all blood circulation so the surgeon can safely repair the heart.

An extreme lowering of the body temperature. A technique used to cool the spinal cord after injury.

a physical condition where wind, wetness and/or altitude take away body heat faster than it can be produced. Pilots flying at height without adequate clothing can suffer hypothermia by wind chill effects on core body temperature. Symptoms (not in any order): lethargy; loss of coordination; loss of concentration; slurred speech; blurry vision; and loss of consciousness.

The dangerous lowering of body temperature under wet, cold conditions. Can lead to death due to exposure.

the cold water hazard for paddlers. Prolonged exposure can lead to incapacitation and eventually death as body core temperature drops below 80 degrees.

Potentially fatal condition a person experiences as their core body temperature falls below normal. Some degree of resistance (and brain illness?) can be achieved by repeated exposure. Hypothermia is the emergency most people preplan for when going underground in northern latitudes.

Hypothermia occurs when the body temperature gets too low. Symptoms include, uncontrollable shivering, memory loss, disorientation, incoherence, slurred speech, drowsiness, and apparent exhaustion.

abnormally low core body temperature to 32° C (95

extremely low body temperature.

This situation occurs when the core temperature of one's body falls below normal. It is the failure of the body to maintain adequate production of heat under conditions of extreme cold.

lowering of body temperature below 95 of

This means a body temperature that is very low.

Abnormally low body temperature caused by exposure to cold and wetness, symptoms of which are sluggishness, reduced mental capacity and apathy.

Abnormally low body temperature; commonly results from exposure to cold and/or wet environments.

A life threatening condition in which the body's temperature are subnormal and the entire body cools.

A fall in the temperature of an animal body below the usual level. This state is brought about when the homeostatic mechanisms fail to maintain adequate production of heat under conditions of extreme cold.

Hypothermia refers to any condition in which the temperature of a body drops below the level required for normal metabolism and/or bodily function to take place. In warm-blooded animals, core body temperature is maintained at or near a constant level through biologic homeostasis. When the body is exposed to colder temperatures, however, its internal mechanisms may be unable to replenish the heat that is being lost to the body's surroundings.
