THERMOREGULATION Flashcards
the process of maintaining the core body temperature at a nearly constant value
thermoregulation
hyperpyrexia
extremely high body temp (above 41.5 C)
hypothermia
below 36.2 C
normothermia
between 36.5 and 37.2 C
elevation in body temperature due to a change in the hypothetical set point
fever
severe hypothermia
less than 30 C
moderate hypothermia
30-34 C
mild hypothermia
34-36 C
normothermia
36.5-37.2 C
hyperpyrexia
more than 41.5 C
hyperthermia
more than 37.2 C
blood vessels dilate, giving flushed appearance, sweat glands become more active
increased temperature
What do we do when we have a decreased temperature?
blood vessels constrict, heat is trapped in deeper tissues. sweat glands become less active. skeletal muscles contract, causing shivering
consequences of hypothermia
prolonged peripheral vasoconstiction, tissue ischemia, tissue necrosis/death
Why should core rewarming be done slowly?
to minimize the risk for dysthymias
