The National Pressure Ulcer Advisory Panel (NPUAP) defines a pressure injury as localized damage to the skin and/or underlying soft tissue, usually over a bony prominence or related to a medical or other device. The injury can manifest as intact skin or an open ulcer and may be painful. The injury occurs as a result of intense and/or prolonged pressure, occasionally in combination with shear. The tolerance of soft tissue for pressure and shear may also be affected by microclimate, nutrition, perfusion, comorbidities, and the condition of the soft tissue.
