Deep Tissue Pressure Injuries: Identification, Treatment, and Outcomes Among Critical Care Patients

Deep tissue pressure injury (DTPI) is a serious form of pressure injuries. The condition remains invisible for up to 48 hours and then progresses rapidly to full-thickness skin and soft tissue loss. Many other conditions that lead to purple skin can be misidentified as DTPI, making the diagnosis difficult at times. A thorough history exploring exposure to pressure is imperative.
