Alternating Air Pressure Mattresses

An alternating pressure mattress cyclically inflates and deflates alternating sets of air cells, such as in two-to-one or three-to-one cycles, to relieve pressure under vulnerable bony prominences. This continuous movement helps redistribute body weight over a larger surface area, offloads sensitive body zones like heels, and aids in the clinical prevention and management of pressure ulcers.

These systems are designed for individuals at risk of developing pressure injuries as well as patients undergoing clinical treatment for existing stage 1, 2, 3, or 4 pressure ulcers. They serve home-care patients, nursing home residents, and hospital patients who experience limited mobility, require prolonged bed rest, or need specialized positioning support during medical recovery.

Selected systems utilize a cell-in-cell configuration, combining active therapy chambers with internal static air bladders that remain inflated if electrical power is lost. Other configurations incorporate a convoluted foam base or closed pneumatic design that prevents bottoming out. These built-in safety features maintain continuous physical support and patient comfort until standard power operation is restored.

Depending on the selected model, systems may combine alternating pressure with true low air loss or micro low air loss for skin microclimate management. Additional therapies include continuous immersion mode, pulsation simulating gentle massage, and lateral rotation up to forty degrees, allowing caregivers to deliver targeted therapy on a single integrated mattress platform.

The Happy Heel feature provides dedicated softness settings across the foot-end air bladders to offload sensitive, fragile heel tissue. Fowler Mode automatically detects changes in the angle of an articulating bed frame when the patient sits up, adjusting air pressures accordingly to provide proper lumbar support and prevent bottoming out during elevation.

Therapeutic surfaces incorporate breathable, fluid-resistant, and antimicrobial top covers to support infection control and protect against shear and friction. Individual air cells crafted from nylon PU or TPU materials can be easily cleaned or individually replaced, minimizing bacterial proliferation and ensuring straightforward decontamination between patient redeployments.
