Pressure injuries (PIs) are defined by the National Pressure Injury Advisory Panel as “localized damage to the skin and/or underlying soft tissue usually over a bony prominence or related to a medical or other device.” Pressure injuries may present as intact skin or as an open ulcer. These wound may be painful. Pressure injuries occur after exposure to prolonged pressure or as a result of pressure in combination with shear. Other factors may affect soft tissue tolerance, such as nutrition, perfusion, microclimate, the presence of comorbidities, and the condition of the soft tissue.
