Pressure ulcers are caused by pressure, rubbing or friction at the weight-bearing bony points of the body (such as hips, heels and elbows). Pressure ulcers most commonly occur in the elderly, or those who are immobile.
Pressure ulcers are classified according to the severity and level of tissue injury:
Stage 1: Persistent non-blanching erythema (redness) of the skin.
Stage 2: Partial-thickness skin loss (epidermis and dermis).
Stage 3: Full-thickness skin loss involving damage of subcutaneous tissue.
Stage 4: Damage extends to the underlying bone, tendon or joint capsule.
Unclassified / Unstageable: Full-thickness tissue loss in which the depth of ulcer is obscured by slough or eschar in the wound bed.
Deep tissue injury: Purple or maroon localized area of discolored intact skin or blood-filled blister caused by damage to underlying soft tissue. The area may feel firmer, boggier, warmer, or cooler compared with surrounding tissue.
