Pressure ulcers develop when the blood supply from capillaries supplying the skin and underlying tissues are constricted enough to hinder perfusion and lead to tissue death. Bony areas of the body, such as the hips, heels, tailbone, shoulder blades, spine, and ankles are the most prone to developing pressure ulcers. Skin breakdown can occur in several ways. First, it can occur when there is an ongoing pressure to a body part. For example, a resident who is placed on their side in bed and cannot turn themselves will have pressure on their hip from their body positioning. Without staff intervention to roll them at regular and frequent intervals, the pressure can result in skin breakdown. Another cause of skin breakdown is friction, or when the skin rubs against another surface, such as bedding. Shearing occurs when two surfaces move in the opposite directions; A common example is when a resident whose upper body is elevated in bed slides down the bed. While a shear injury will not be seen at the skin level because the injury happens to the tissue beneath the skin, it is often coupled with friction injury that is seen on the skin’s surface.
