Claim 6:
7. An air mattress system comprising:
an air compressing device;
a first pressure valve; and
a second pressure valve;
a therapy air mattress having release ports that maintain a controlled release of air;
a patient transfer mattress having cushion outlets on an underside of the patient transfer mattress that release air to form an air cushion;
wherein the air compressing device is operable to introduce air from the first pressure valve to the therapy air mattress at a first volumetric flow rate within a first volumetric flow rate range, and, on demand, to introduce air from the second pressure valve to the patient transfer mattress at a second volumetric flow rate within a second volumetric flow rate range while continuing to supply air to the therapy air mattress at a volumetric flow rate within the first volumetric flow rate range, the patient transfer mattress thereby releasing air through the cushion outlets to generate the air cushion, the air cushion providing sufficient lift to reduce the force of friction between the patient transfer mattress and a resting surface, the air compressing device comprising a first compressor and a second compressor each contained within a housing, the first compressor fluidically coupled to the first pressure valve and the second compressor fluidically coupled to the second pressure valve.
