Abstract
Disclosed herein is a fluidization patient support system that enables decrease and elimination of the unpleasant and aggravating "pinging" sensation to which patients are presently exposed. The flow rate of air to the plenum chamber beneath the diffuser and fluidization material is controlled by a valve in the air flow conduit, there being a diversionary discharge outlet at the valve, such that the valve can control the ratio of air flow to the diversionary outlet and to the plenum.
