EMT HOSA - Environmental
Emergencies
conduction - Answer-the transfer of heat from one material to another through direct contact
water chill - Answer-chilling caused by conduction of heat from the body when the body or clothing is
wet
convection - Answer-carrying away of heat by currents of air, water, or other gases or liquids
wind chill - Answer-chilling caused by convection of heat from the body in the presence of air currents
radiation - Answer-sending our energy, such as heat, in waves into space
evaporation - Answer-the change from liquid to gas; when the body perspires or gets wet, evaporation
of the perspiration or other liquid into the air has a cooling effect on the body
respiration - Answer-breathing; during respiration, body heat is lost as warm air is exhaled from the
body
hypothermia - Answer-generalized cooling that reduces body temperature below normal, which is a life-
threatening condition in its extreme; predisposing factors include: injuries, chronic illness, shock,
infection, and diabetes with hypoglycemia
when to consider hypothermia - Answer-alcohol ingestion (intoxication in cold weather), underlying
illness (disorders susceptible to cold), overdose/poisoning (unconscious on a cold floor, sweating in a
