A method and device for controlling sleep disorder breathing utilizes variable multiple level pressures. A pressure source (43) supplies compressed breathable gas at a relatively low pressure to the user's airway. Pressure transducers (45, 48) monitor pressures and convert them into electrical signals. The electrical signals are filtered and processed (49, 55) to extract specific features such as duration and energy levels. If these features exceed selected threshold values for duration and energy level over a minimum period of time, then the microprocessor (57) declares the presence of sleep disorder breathing. If a selected number of these events occur within a selected time period, then the microprocessor adjusts the pressure delivered by the pressure source. If sleep disorder breathing is not detected within a certain time period, then the microprocessor lowers the pressure level gradually. The device and method disclosed in this patent is capable of detecting apnea, hypopnea, and pharyngeal wall vibration. Further, it is able to distinguish between obstructive, central and mixed apnea and hypopnea.
