(Print)
do not use direct heat to rewarm skin (fires, radiators, etc)
ice crystals form, damaging cells and blood vessels
affects dermis, epidermis, and fatty tissue, may blister
put dressing between toes and avoid walking
fingers, toes, nose, ears, cheeks and chin
involves all layers of the skin and causes permanent tissue damage.
let area dry, rubbing can cause tissue damage
irritates the skin, causing redness, prickling and a cold feeling followed by numbness
shivering, slurred speech, weak pulse, shallow breathing
medications that constrict your blood vessels
1st layer allows skin to breathe
get out of the cold
change clothing out of cold/wet clothes
layer clothing
wrap with sterile dressing, keep dry, rewarm twice a day
keep entire body covered when going outside in cold
rewarm area with warm (not hot) water or breath on it and hold close
irritates the skin
hypothermia
2nd layer absorbs sweat and is windproof
wind chill
avoid rewarming then re-exposing to cold, this can cause worse damage
increase hydration/calorie intake
if skin is turning hard, white or black, or has lost feeling
