Originally designed for managing burns, the air-fluidized therapy bed is now used for patients with various debilities. By allowing harmless contact between the bed’s surface and grafted sites, the bed promotes comfort and healing.

The traditional air-fluidized therapy bed is actually a large tub that supports the patient on a thick layer of silicone-coated microspheres of lime glass. Another version combines the air-fluidized section with a low-air-loss or cushioned section. (See The air-fluidized therapy bed.) A monofilament polyester filter sheet covers the microsphere-filled tub. Warmed air, propelled by a blower beneath the bed, passes through it. The resulting fluid-like surface reduces pressure on the skin to avoid obstructing capillary blood flow, thereby helping to prevent pressure ulcers and to promote wound healing.¹ The bed’s air temperature can be adjusted
to help control hypothermia and hyperthermia. The microprocessor technology also allows manipulation of various sections of the unit for optimum adjustment. Some models come with adjustable back and leg supports to promote positioning.

The air-fluidized therapy bed may be contraindicated for a patient with an unstable spine. It may also be contraindicated for a patient who can’t mobilize and expel pulmonary secretions because the lack of back support impairs productive coughing. Operation of the air-fluidized therapy bed is complex and requires special training.
