Abstract
A modular construction, low air loss patient support system includes a plurality of identical multi-chambered inflatable sacks, a microprocessor, a plurality of pressure control valves with pressure transducers and a plurality of flow diverter valves for switching between different modes of configuring the manner in which the sacks are pressurized. The system includes a modular manifold for mounting the pressure control valves, and a modular support member for mounting the sacks via quick-disconnect couplings and having air flow channels defined therethrough. The support system effects a method of rotating or tilting the patient. The support system permits practicing the method of relieving pressure points between the patient and the sacks while elevating the head and chest of the patient.
