ABSTRACT:
In the treatment of obstructive sleep apnea, a CPAP flow generator is employed to direct air to a nasal mask fitted to a patient. The airflow from the generator is monitored, and the flow and/or pressure is increased when the waveform of the airflow exhibits characteristics corresponding to flow limitation. The generator may be controlled to repetitively test for waveform variations, in order to adjust the CPAP flow to the minimum level the does not produce flow limitation.
