2016 National Pressure Ulcer Advisory Committee (NPUAP) on pressure injury divided into 4 stages (29): Stage 1: intact skin with erythema with constant digital pressure. Stage 2: partial cortical defect with dermal exposure. Phase 3: full-thickness defect of skin with exposed adipose tissue, usually visible granulation tissue or internal roll of wound edge, and local slough and/or eschar. Ulcers, with visible or palpable fascia, muscle, tendon, ligament, cartilage or bone exposed, may also have slough and/or eschar localized to the full thickness of the skin and tissue defects in Stage 4
