Ch 35 Environmental Emergencies Flashcards
The transfer of heat from one material to another through direct contact
Conduction
Chilling caused by conduction of heat from the body when the body or clothing is wet
Water chill
Carrying away of heat by currents of air, water, or other gases or liquids
Convection
Chilling caused by convection of heat from the body in the presence of air currents
Wind chill
Sending out energy, such as heat, in waves into space
Radiation
The change from liquid to gas; has a cooling effect on the body
Evaporation
Breathing; body heat is lost as warm air is exhaled from the body
Respiration
Generalized cooling that reduces body temperature below normal, which is a life-threatening condition in its extreme
Hypothermia
Covering a hypothermic patient and taking other steps to prevent further heat loss and help the body rewarm itself
Passive rewarming
Application of an external heat source to rewarm the body of a hypothermic patient
Active rewarming
Application of heat to the lateral chest, neck, armpits, and groin of a hypothermic patient
Central rewarming
Cooling or freezing of particular parts of the body
Local cooling
An increase in body temperature above normal, which is a life-threatening condition in its extreme
Hyperthermia
The process of experiencing respiratory impairment from submersion/immersion in liquid, which may result in death, morbidity (illness or other adverse effects), or no morbidity
Drowning
Gas bubble in the bloodstream
Air embolism (pl: emboli) [more accurate term: arterial gas embolism (AGE)]
