The RecoverAir 3000B is a powered bariatric mattress replacement that uses both alternating pressure and low air loss to treat moderate to severe pressure ulcers. Progressive alternating pressure promotes lower interface pressures and increased circulation to stimulate pressure ulcer treatment. Low Air Loss provides moisture and temperature control and improved patient comfort. The top cover is highly vapor permeable and oversized, thus reducing risk of friction, shear and complications of incontinence. As a mattress replacement system, the RecoverAir 3000B can be used with existing patient bed frames.
