Claim Text:
1. A method for controlling a pressurized mattress system, said pressurized mattress system having an upper surface for receiving a patient thereon, said pressurized mattress system including: at least one zone having at least one inflatable air bladder, a substrate disposed below said at least one inflatable air bladder, a pressure sensor for measuring a zone air pressure of said at least one zone, a plurality of interface pressure sensors disposed on an upper surface of said at least one inflatable air bladder, each of said plurality of interface pressure sensors measuring an interface pressure at a discrete location along said upper surface of said at least one inflatable air bladder, a source of pressurized air, and a controller for receiving signals from said pressure sensor and said plurality of interface pressure sensors and for controlling the flow of pressurized air to/from said at least one inflatable air bladder based on said signals, wherein said controller calculates a zone interface pressure for said at least one zone based on said signals from said plurality of interface pressure sensors, said method comprising the steps of: wherein said step d) of pressurizing the at least one zone to an optimal zone air pressure includes the steps of:
