What is a pressure injury?
A pressure injury is localized damage to the skin and underlying soft tissue usually over
a bony prominence or related to a medical or other device.
The injury can present as intact skin or an open ulcer and may be painful.
What do pressure injuries result from?
The injury occurs as a result of intense and/or prolonged pressure or pressure in
combination with shear.
The tolerance of soft tissue for pressure and shear may also be affected by
microclimate, nutrition, perfusion, co-morbidities and condition of the soft tissue.
What is a stage 1 pressure injury?
Non-blanchable erythema of intact skin
Intact skin with a localized area of non-blanchable erythema, which may appear
differently in darkly pigmented skin.
Presence of blanchable erythema or changes in sensation, temperature, or firmness
may precede visual changes.
, Color changes do not include purple or maroon discoloration; these may indicate deep
tissue pressure injury.
What is a stage 2 pressure injury?
Partial-thickness loss of skin with exposed dermis.
The wound bed is viable, pink or red, moist, and may also present as an intact or
ruptured serum-filled blister.
Adipose (fat) is not visible and deeper tissues are not visible.
Granulation tissue, slough and eschar are not present.
These injuries commonly result from adverse microclimate and shear in the skin over
the pelvis and shear in the heel.
What is a stage 3 pressure injury?
Full-thickness loss of skin, in which adipose (fat) is visible in the ulcer and granulation
tissue and epibole (rolled wound edges) are often present.
Slough and/or eschar may be visible.
The depth of tissue damage varies by anatomical location; areas of significant adiposity
can develop deep wounds.
