Abstract
The pressure of breathable gas exiting a flow generator is controlled by adjusting the efficiency of the flow generator. In one embodiment, a baffle plate of a control element can restrict the open entry area of a motor driven turbine of the flow generator. In another embodiment, the degree of opening of the mouth of the flow generator inlet is automatically adjustable in response to the needs of the user, hence creating a pneumatic impedance, and which simultaneously controls, in the same manner, the impedance of the outlet of the device.
