Most pressure ulcers develop over bony prominences, where friction and shearing force combine with pressure to break down skin and underlying tissues. Common sites include the scarum, coccyx, ischial tuberosites, and greater trochanters. Other common sites include the skin over the vertebrae, scapulae, elbows, knees, and heels in bedridden and relatively immobile patients.
Causes: Shear and Friction of skin, Pressure on bony prominences, Poor nourishment, Limited mobility, Poor circulation
Prevention is Key: to avoid extensive tissue damage. Preventive measures include ensuring adequate nourishment and mobility to relieve pressure and promote circulation. It is important to evaluate each patient's risk of developing pressure ulcers. Use the Braden Scale to calculate the risk of developing a pressure ulcer.
