How quickly can a pressure injury develop?

A pressure injury, also known as a pressure ulcer or decubitus ulcer, can develop quite rapidly due to unrelieved pressure on the skin and underlying tissues, particularly over bony prominences. It is well documented that pressure injuries can begin to manifest within as little as 2 to 6 hours of sustained pressure, especially in individuals with limited mobility or compromised circulation. The timeframe is influenced by various factors, such as the individual's overall health, skin integrity, moisture levels, and the amount of pressure applied. Early recognition and intervention are crucial for preventing the progression of these injuries, which can lead to serious complications if not addressed in a timely manner. Understanding this quick onset emphasizes the importance of regular repositioning and skin assessments for at-risk patients.
