The effect of using a low-air-loss surface on the skin integrity of obese patients: results of a pilot study.

Obese patients often are immobile, acutely ill, and at high risk for developing pressure ulcers when admitted to acute care facilities. Pressure-relieving mattresses are an integral part of a pressure ulcer prevention plan of care. Patients with a body mass index (BMI) >35, weight between 250 and 500 lb, and a minimum 3-day length of stay were recruited to participate in a pilot study to evaluate the safety and use of a new low-air-loss, continuous lateral rotation bariatric bed.
