Best Alternating Pressure Immersion Mattresses for Hospital Beds

Pricing is not specified directly as costs vary depending on system specifications, dimensions, weight capacity, and whether non-powered foam, powered low air loss, or multi-therapy alternating pressure models are selected. Equipment distributors, fleet operators, and healthcare facilities can request a personalized quote based on their specific patient support and clinical therapy requirements.

These mattresses utilize cyclic inflation and deflation of air bladders to shift pressure points across the patient body. By redistributing interface pressure over a greater contact area and allowing the body to immerse and envelop into the surface, blood flow is maintained to vulnerable tissue areas, significantly lowering the risk of skin breakdown and deep tissue injury.

Several models feature specialized backup technology to prevent bottoming out. For example, systems like the Rhythm Multi Plus and Duet incorporate a 2-inch convoluted foam base for secondary support. Others, like the Enhance RDX and Salute RDX, use cell-in-cell air bladder designs where sealed static chambers remain inflated to support the patient during outages.

Mattress models accommodate a wide spectrum of patient weights to suit standard and bariatric needs. Non-powered foam systems typically support user limits of 350 lbs, while standard powered hybrid units handle between 350 and 500 lbs. Bariatric specialty models, including the Rhythm Multi, Century Gold, and MOXI Bari Select Air, accommodate weights up to 1,000 lbs.

Support surfaces utilize dedicated heel offloading features. Systems like the Rhythm Multi Plus incorporate Happy Heel technology with selectable softness settings in the foot-end air cells, while foam systems such as the DLX and VLX feature dedicated heel-soft visco-elastic zones or sloped profiles that float the heels to minimize pressure and shear forces.

Low air loss therapy continuously directs air across the surface cover to assist in microclimate management. By aiding moisture dissipation and controlling surface temperature, it maintains an optimal skin microclimate. This reduces tissue maceration and skin breakdown, particularly for bed-bound individuals or high-risk patients managing advanced stage 1 through 4 pressure ulcers.
