What is a common characteristic of a pressure ulcer?

Local loss of sensation is a common characteristic of a pressure ulcer. As a pressure ulcer develops, the sustained pressure on the skin and underlying tissues can disrupt blood flow, leading to tissue ischemia. This ischemia can result in nerve damage in the affected area, which may manifest as a loss of sensation. Patients may not feel pain or discomfort in the area of the ulcer, even if surrounding tissues are injured. Recognizing the local loss of sensation is crucial for assessment and treatment, as it highlights the severity of tissue compromise.

Other characteristics of pressure ulcers may include changes in skin color or temperature, but local loss of sensation distinctly underscores the impact of prolonged pressure on sensory function. Understanding this aspect aids in identifying patients at risk and implementing appropriate interventions to prevent progression.
