Claim:
1. A respiratory treatment system comprising: a flow pressurizer apparatus configured to generate a pressurized flow of air through a fine bore delivery conduit toward a patient interface; a treatment compensator coupled with the fine bore delivery conduit at the patient interface and configured to reduce a first pressure from the fine bore delivery conduit to a second pressure for delivery to a patient from the treatment compensator, the second pressure being above atmospheric pressure; and a processor configured to control adjustments to the first pressure generated by the flow pressurizer apparatus, wherein the flow pressurizer apparatus comprises a first flow generator and second flow generator, each flow generator comprising a motor with impeller and volute, wherein the first flow generator is configured to generate a fixed pressure to overcome pressure drop introduced by the fine bore delivery conduit, and wherein the second flow generator is configured to dynamically generate treatment pressure to different levels of pressurization above the fixed pressure.
