chpter 31 environmental trauma Flashcards
active rewarming
application of an external heat source to rewarm the body of a hypothermic patient.
central rewarming
application of heat to the lateral chest, neck, armpits, and groin of a hypothermic patient.
conduction
the transfer of heat from one material to another through direct contact.
convection
carrying away of heat by currents of air, water, or other gases or liquids.
air embolism
gas bubble in the bloodstream. The plural is air emboli. The more accurate term is arterial gas embolism (AGE).
decompression sickness
a condition resulting from nitrogen trapped in the body’s tissues, caused by coming up too quickly from a deep, prolonged dive
hyperthermia
an increase in body temperature above normal, which is a life-threatening condition in its extreme.
hypothermia
generalized cooling that reduces body temperature below normal, which is a life-threatening condition in its extreme.
local cooling
cooling or freezing of particular (local) parts of the body.
passive rewarming
covering a hypothermic patient and taking other steps to prevent further heat loss and help the body rewarm itself
toxins
substances produced by animals or plants that are poisonous to humans.
water chill
chilling caused by conduction of heat from the body when the body or clothing is wet.
wind chill
chilling caused by convection of heat from the body in the presence of air currents.
When performing active rewarming, you should:
not delay transport.
what is typically a source of heat for the body?
Shivering
