Abstract
A method and apparatus to comfortably support a patient on an inflatable chamber. The support apparatus includes an inflatable mattress and a pump to correct the pressure of the mattress. An inflatable chamber is provided below the mattress to act as a pressure transducer. When the difference in pressure between the inflatable mattress and the inflatable sensor reaches a predetermined value, a controller actuates a correction device including a pump and a release valve to correct the pressure of the inflatable mattress. The apparatus allows the mattress to be automatically maintained at a desirable pressure.
