-
intact skin with a localized area of non- blanchable erythema (red) usually over a bony prominence
stage 1 pressure ulcer
-
partial thickness skin loss with exposed dermis; serum filled or ruptured blister. ulcers are open but shallow and with red pink wound bed
stage 2 pressure ulcer
-
full thickness loss. No bone or muscle is visible
stage 3 pressure ulcer
-
full thickness and tissue loss with exposed bone, muscle, tendon, ligament or cartilage
stage 4 pressure ulcer
-
injuries related to devices being used
Medical device related pressure injury
-
an area of skin that is intact but discolored. It might be purplish or deep red, painful, boggy, or have a blister
suspected deep tissue injury
-
full thickness covered by eschar or slough
unstageable pressure ulcer
-
usually soft, stringy and pale yellow or gray
slough
-
thick, hard, black or brown, leather like (dead tissue)
eschar (unstageable pressure ulcer)
-
pathway away from the wound (causes delayed wound healing)
tunneling
-
checking the cliff of skin hanging over wound
undermining
-
a roll of skin that develops at the edge of the wound that has formed a boarder (closed or rolled wound edges)
epibole
-
When a wound involves minimal or no tissue loss and has edges that are well approximated. (little scaring expected)
primary intention healing
-
Occurs when a wound (1) involves extensive tissue loss, which prevents wound edges from approximating, or (2) should not be closed (because it is infected)
secondary intention healing
-
a form of connective tissue with an abundant blood supply
granulation
-
when two surfaces of granulate tissue are brought together. This technique may be used when the wound is clean contaminated or contaminated. (creates less scaring than does secondary, but more than primary intention healing)
tertiary intention healing (delayed primary closure)
-
fluid that oozes as a result of inflammation
exudate
-
used on clean wounds. Watery in consistency and contains very little cellular matter. consist of serum (small colored fluid that seperates out of blood when a clot is formed)
serous exudate
-
you will see this with deep wounds or wounds in highly vascular areas. A bloody drainage, indicted damage to capillaries
Sanguineous exudate
-
A combination of bloody and serous damage. in new wounds, you will most commonly see this
Purulent exudate
-
red tinged pus
Purosanguineous exudate
-
whenever a capillary network is interrupted or a blood vessel is served, bleeding occurs. This usually occurs within minutes of the injury
hemostasis
-
a red blue collection of blood under the skin, which forms as a result of bleeding that cannot escape to the surface
hematoma
