Abstract
An air flow device and a method useful for the treatment of upper airway disordered breathing. The invention provides an airflow device having a means for delivering variable pressure levels of breathable air to a patient's respiratory system with a means for controlling the time during which the delivered pressurized air rises from an initial pressure level to a higher operating pressure level. The device increases the pressure level of gas delivered to the patient over a plurality of breaths taken by the patient. This type of device is useful for treating a wide variety of sleeping and breathing disorders.
