More Information
Summary:A patient-support apparatus (100) includes an inflatable support structure (112), a variable output pump (114), a power supply (140) and a controller (116). The pump includes a driver that is responsive to variations in the power signal applied to the driver to vary the output from the pump. The pump output is varied depending on the amount of flow needed as determined by a sensor that senses the pressure in the inflatable support structure.
