Basics

Description

  • A localized area of skin or underlying tissue injury resulting from pressure and/or shear
  • Classified in stages according to the National Pressure Ulcer Advisory Panel (NPUAP):
    • Stage I: nonblanchable erythema—intact skin with nonblanchable redness; darkly pigmented skin may not have visible blanching.
    • Stage II: partial thickness skin loss—shallow open ulcer with a red-pink wound bed, without slough; or intact or open/ruptured serum-filled blister
    • Stage III: full thickness skin loss—subcutaneous fat may be visible but bone, tendon, or muscle is not exposed; slough, if present, does not obscure depth of tissue loss.
    • Stage IV: full thickness tissue loss—exposed bone, tendon, or muscle; slough or eschar may be present but does not completely obscure wound base.
    • Unstageable: depth unknown—base of the ulcer is covered by slough and/or eschar in the wound bed.
    • Suspected deep tissue injury: depth unknown—purple or maroon area of intact skin or blood-filled blister
  • Synonyms: decubitus ulcer; bedsore; pressure injury
