Decubitus ulcer
Last Updated: 11/26/2011
A pressure ulcer is an area of skin and tissue that becomes injured or broken down. Generally, pressure ulcers occur when a person is in a sitting or lying position for too long without shifting his or her weight. The constant pressure against the skin causes a decreased blood supply to that area. Without a blood supply, the area cannot survive and the affected tissue dies.
