There are many factors attributing to the risk of pressure ulcers. Pressure ulcers are acquired as a result of prolonged periods of immobility during unrelieved pressure which compresses tissues that overlie in bony prominences. The principal factor in pressure ulcer development is excessive tissue pressure that prevents the normal supply of blood to the affected area. The severity of skin and tissue damage will depend on how long the patient had been exposed. Prevention is the best intervention for pressure ulcers. There are several risk factors that have been identified to make a patient more vulnerable to acquiring a pressure ulcer.
