Abstract
An air delivery system that includes an inflatable cushion device adapted to support at least a portion of a body of a user. The air delivery device includes a supply conduit in fluid communication with both an interior region of the inflatable cushion device and a controller. Using a pressure sensor, the controller is adapted to relatively continuously measure a static air pressure level of the interior region and compare the measured static air pressure level to a target air pressure level. Further, the controller is adapted to intermittently operate an air pump. Moreover, the controller may operate the air pump when measured static air pressure is below the target static air pressure level, and deactivate operation of the air pump, which may include maintaining the air pump in an un-operated condition when the measured static air pressure is within the target static air pressure level.
