Low Air Loss Alternating Pressure Mattresses

The best system depends on the individual clinical application and patient requirements. Options range from standard alternating pressure surfaces such as the Salute RDX and Enhance RDX to multi-therapy models like the Duet, DynaFlow Immersion, and Rhythm series, which combine low air loss with pulsation, lateral rotation, or bariatric weight capacities up to 1,000 lbs.

Alternating pressure systems utilize inflatable air bladders that periodically inflate and deflate in programmed cycles, such as 2-1 or 3-1 alternation. By continuously shifting support zones across the body, these systems offload interface pressure from vulnerable tissue, improve blood flow, and assist in both preventing pressure ulcers and treating existing stage 1 through stage 4 wounds.

Many models feature integrated power outage protection to safeguard patients during power interruptions. Depending on the system, this includes cell-in-cell bladders with static air chambers, sealed closed-loop air systems that keep cells inflated, or integrated 2-inch convoluted foam bases that deliver continuous underlying physical support until electrical power is restored.

Our low air loss mattress portfolio provides support surfaces tailored to a broad range of clinical needs. Standard therapeutic models support patient capacities such as 350 lbs, 440 lbs, or 500 lbs, while bariatric configurations such as the Century Gold, Rhythm Turn, Rhythm Multi Plus, and MOXI Bari Select Air accommodate weights up to 750, 850, or 1,000 lbs.

Select systems include specialized operational modes to streamline patient care. A firm mattress mode or patient care mode temporarily max-inflates air cells to assist medical staff during dressing changes, examinations, and patient ingress or egress. In addition, Fowler modes detect bed frame elevation changes and automatically boost pressure to prevent patient bottoming out.

Several models incorporate designated heel relief zones to protect vulnerable lower extremities. For example, systems featuring Happy Heel or Happy Feet technology provide softer selectable settings or lower air cells across the final sections of the mattress, effectively offloading pressure and reducing shear forces at the patient fragile heel area.
