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