Pressure Sore Causes

Causes of Pressure Sores

---

Continuous pressure When there is a pressure pushing on one area of the skin, and there is bone on the other side, the skin and the tissue underneath it are at risk of not getting adequate blood supply. There may then be deficient oxygen and other vital nutrients as a result, meaning that skin and tissue could become damaged. Friction Healthy, mobile people sometimes take for granted their ability to adjust their posture during the day when for some people this is actually very difficult, putting them at risk of pressure sores. Many patients find that moving position and turning can easily damage the skin and therefore increases the risk of them developing pressure sores. Shear This is a term used to describe when the skin moves one way and the bone beneath it moves another. For example, a patient who mistakenly slips down a chair or bed is at risk of shearing.
