air-fluidized bed

air-fluidized bed,

a bed with body support provided by thousands of tiny soda-lime glass beads suspended by pressurized, temperature-controlled air. The patient rests on a polyester filter sheet that covers the beads. The special bed is designed for use by patients with or at risk for posterior pressure ulcers or with posterior burns, grafts, or donor areas. The pressure against the patient's skin surface is less than the capillary refilling. The improved capillary blood flow to the skin speeds the growth of granulation tissue.
