What is a pressure ulcer?

A pressure ulcer is defined as an injury to the skin and underlying tissue that occurs as a result of prolonged pressure on the skin. This condition typically develops in areas where bones are close to the skin, such as on the heels, hips, and buttocks. When pressure is applied to these areas for an extended period, it restricts blood flow to the skin and tissue, leading to tissue damage and breakdown.

The primary factors contributing to the development of pressure ulcers include immobility, poor nutrition, moisture, and friction. Understanding that pressure ulcers result specifically from sustained pressure helps healthcare providers focus on preventive measures such as regular repositioning of patients, ensuring adequate nutrition, and maintaining skin integrity. This makes the identification of pressure ulcers crucial in the care of individuals who are bedridden or have limited mobility.
