2.1.3. Pressure ulcers Tissue anoxia and ischemia result in necrosis, sloughing, and tissue ulceration Common sites Predisposing factors Longer healing periods Stages: STAGE I A persistent area of skin redness (without a break in the skin) that does not disappear when pressure is relieved. STAGE II A partial thickness loss of skin layers involving the epidermis that presents clinically as an abrasion, blister, or shallow crater. “STAGE III​ A full thickness of skin is lost extending through the epidermis and exposing the subcutaneous tissues; presents as a deep crater with or without undermining adjacent tissue” STAGE IV​ A full thickness of skin and subcutaneous tissue is lost, exposing muscle, bone, or both; presents as a deep crater that may include necrotic tissue, exudate, sinus tract formation, and infection. Q2 turns, proper assessment, proper hygiene and cleaning of patients can all reduce the risk of pressure ulcers mepilex can be used to reduce friction and shear when a patient has or is at risk for pressure ulcers
