Pressure Injury Flashcards
what is a pressure injury
localized skin and underlying tissue damage
*usually over a bony prominence
common PI sites
hips
sacrum
heels
back of head
PI usually in combination with
shear
*layers of skin separate
time and pressure for PI to occur
2 hours
30 mmhg
slough
moist, stringy, and yellow/gray necrotic tissue
what dressing should you use for slough
dakin soaked
eschar
devitalized dermis that is leathery/thick/black
undermining
area of ulcer beneath skin surface that extends under the edge of wound
tunneling
narrow extensions into surrounding tissue from sides of ulcer
*also called SINUS TRACTS or FISTULA
*ends in another structure of hollow viscous
stage 1 PI
skin INTACT
non blanchable redness
protection for stage 1 PI
protect from:
moisture
pressure
further injury
stage 2 PI
partial thickness loss of skin with exposed dermis
*shallow and open (could be a blister)
*NO slough, eschar, or granulation
stage 3 PI
full thickness loss
*SUBQ may be visible
*NO bone, tendon, muscle (3) exposed
*epibole (rolled edges)
*possible slough and eschar
*undermining and tunneling possible
stage 4 PI
full thickness and tissue loss
*bone, ligament, tendon, muscle (4) exposed
*epibole, slough, eschar, tunneling, undermining may be present
unstageable
full thickness tissue loss and base cannot be seen
