Jason Y1 - 2021 N1 - T2 - The Atlas of Emergency Medicine, 5e AB - Decubitus ulcers develop when soft tissue is compressed between a bony prominence and a hard external surface. Tissue compression results in decreased blood flow, tissue ischemia, and cell death. Pressure, shearing forces, friction, and excessive moisture contribute to formation. Areas commonly affected include the sacrum and heels. Immunocompromised, nursing home, neurologically impaired, and immobilized trauma patients are at high risk.
