Alternating Pressure Mattress and Pump Systems

An alternating pressure mattress is designed for the prevention and treatment of pressure ulcers from Stage 1 through Stage 4. By inflating and deflating air cells in specific cycles—such as 2-in-1 or 3-in-1 sequences—the system redistributes pressure over a wider surface area, unloads vulnerable anatomical points like heels, and promotes tissue perfusion.

Multiple systems utilize integrated safety features to maintain inflation without power. For instance, the Enhance RDX and Salute RDX employ an 8-inch cell-in-cell configuration with 3.5 inches of static air support, while the Rhythm Multi, Duet, and DynaFlow systems incorporate a 2-inch convoluted foam base to support the patient continuously.

Weight capacities vary by system configuration to meet diverse clinical profiles. Standard therapeutic models accommodate user limits such as 350 lbs or 440 lbs, while standard bariatric models support 500 lbs. High-capacity configurations in the Century Gold, Rhythm Multi, and DynaFlow series accommodate patient weights up to 750 lbs or 1,000 lbs.

Selected models feature dedicated heel relief engineering. The Rhythm Multi and Rhythm Multi Plus include Happy Heel technology offering three selectable softness settings across the final four air bladders, while the Salute RDX incorporates Happy Feet with dedicated softness in the last five air cells to protect fragile heel tissue.

Depending on the model, systems combine several advanced modalities into one powered unit. Therapies include continuous low air loss for moisture and microclimate management, pulsation mode for comfort, 40-degree lateral rotation to assist patient turning, static immersion mode, and standard multi-cycle alternating pressure therapy.

Advanced units such as the Duet and DynaFlow Immersion systems include Fowler Mode detection. This feature senses angle changes when the bed frame head is elevated, automatically adjusting bladder pressures to prevent the patient from bottoming out while maintaining clinical pressure redistribution in an upright seated position.
