J Clin Nurs. 1999 Mar;8(2):206-16. doi: 10.1046/j.1365-2702.1999.00254.x.


Based on a review of the literature related to the prediction and prevention of pressure sores, a conceptual scheme on pressure sores in introduced. The article highlights the four elements of the scheme: pressure, shearing force, tissue tolerance for pressure and tissue tolerance for oxygen. Factors influencing pressure and shearing forces, the pressure distribution capacity of tissue, the oxygen need of tissue and oxygen supply to tissue are discussed.
