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