Ch25&26 Key Terms - Cold/Heat Related Emergencies Flashcards
A continued drop in core body temperature after removal from exposure to the cold.
Afterdrop
Damage to tissues from freezing due to the formation of ice crystals between and within cells, rupturing the cells and leading to cell death.
Frostbite
A relatively minor, local cold injury that results from local vasoconstriction of blood vessels in response to cold.
Frostnip (chilblains)
An abnormally low body temperature; below 35’C (95’F).
Hypothermia

Thermoregulation
The apparent temperature felt on exposed skin; is a function of the air temperature and wind speed.
Wind chill
The temperature in the immediate environment
Ambient temperature
The temperature in the part of the body that contains the vital organs.
Core body temperature
Adaptation of the body over time to a hot environment
Heat acclimatization
A measure of the risk for heat illness; combines the effects of increasing ambient temperature and increasing humidity.
Heat index
The amount of water vapor in the air.
Humidity
Elevated core body temperature
Hyperthermia
