What condition is a pressure ulcer primarily associated with?

A pressure ulcer, also known as a pressure sore, bedsore, or decubitus ulcer, is primarily associated with localized pressure. This condition develops when there is sustained pressure on the skin, particularly over bony prominences, which restricts blood flow to the area. When blood flow is compromised, the skin and underlying tissues can become damaged, leading to ulcers.

The pressure can come from various sources, such as prolonged sitting or lying in one position without relief. Risk factors include immobility, increased age, and certain medical conditions that affect blood circulation or skin integrity. While factors like excess moisture, inadequate nutrition, and shearing forces can contribute to skin breakdown or worsen existing wounds, localized pressure is the principal cause of pressure ulcer development. Understanding the relationship between pressure and skin integrity is crucial in infection prevention and care in nursing homes and other healthcare settings.
