Tipo de ferida

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.

Stage 2 Pressure Injury: Partial-thickness skin loss with exposed dermis
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.

Stage 3 Pressure Injury: Full-thickness skin loss
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.

Stage 4 Pressure Injury: Full-thickness skin and tissue loss
Full-thickness skin and tissue loss with exposed or directly palpable fascia, muscle, tendon, ligament, cartilage or bone in the ulcer. Slough and/or eschar may be visible.

Open surgical wounds are left to heal by secondary intention, which involves leaving wound to heal naturally, and relies on granulation tissue arising from the base of the wound to fill the tissue deficit created by surgery.

In closed wounds, the skin edges are re-approximated by stitches, staples, tissue adhesives or adhesive strips and left to heal by primary intention.

Traumatic wound occurring on the extremities of older adults as a result of friction alone or shearing and friction forces.
