5 ways the body loses heat
-conduction
- convection
- evaporation
- radiation
-respiration
lowering of the bodycore temp to below 95 degrees
hypothermia
s/s of mild hypothermia
s/s moderate hypothermia
core temp is 86-93 degrees
shivering stops
muscular activity decreases
pulse/respirations start to slow down
s/s of severe hypothermia
core temp is less than 86 degrees
pt becomes lethargic and stops fighting
treatment for mild hypothermia
remove from environment
apply hot packs
treatment for moderate/severe hypothermia
freezing of the skin but not the deeper surface
frostnip
most serious local cold injury because the tissues are actually frozen
frostbite
treatment for frostbite
cushion and splint
body core temp is higher than 101 degrees
hyperthermia
painful muscle spasms caused by loss of water and electrolytes
heat cramps
treatment for heat cramps
remove from environment
give fluids by mouth
s/s of heat exhaustion
dizziness, weakness, nausea/vomiting, cold clammy skin
treatment for heat exhaustion
remove from environment
give pt water slowly if alert
loosen up clothing
s/s of heat stroke
hot flushed dry skin
aloc
bp drops
treatment for heat stroke
active rapid cooling; ice packs
dive emergency-air embolism
when the diver holds his or her breath during a rapid ascent
can result from ascent for staying down too long
decompression sickness
(the bends)
