Pressure ulcers: Back to the basics - PubMed Central (PMC)

External pressure of more than 33 mm Hg occludes the blood vessel so that the underlying and surrounding tissues become anoxic and if the pressure continues for a critical duration, cell death will occur, resulting in soft tissue necrosis and eventual ulceration. As the new definition suggests, prolonged pressure is the leading contributing factor.
