A gas delivery system that generates a pressurized flow of breathable gas for delivery to a patient. The system includes a primary gas delivery system for delivering a flow of pressured gas to the airway of a patient and supplemental gas delivery system. The supplemental gas delivery system is in the form of a modular gas regulator assembly that regulates the flow of supplemental gas from a gas source to the primary gas delivery system so that supplemental gas is delivered to the patient concomitant with the pressurized flow of breathable gas. The system allows the user to selectively control the gas concentration level of the supplemental gas, such as oxygen, helium, nitrogen or any combination thereof, and the pressurized flow of breathable gas delivered to the patient concomitantly.
