1. A respiratory interface apparatus, comprising: a patient contacting portion structured to engage a face of a patient;a common chamber fluidly coupled to the patient contacting portion;a first control chamber;a first flow regulating mechanism provided between the first control chamber and the common chamber;a second control chamber;a second flow regulating mechanism provided between the second control chamber and the common chamber;a first conduit;a second conduit; anda pressure source including a controller,wherein the first flow regulating mechanism is a first active valve controlled by the controller and is structured to selectively fluidly couple the first control chamber to the common chamber, and wherein the second flow regulating mechanism is a second active valve controlled by the controller and is structured to selectively fluidly couple the second control chamber to the common chamber,wherein the controller is structured to actuate the first active valve in a first predetermined manner and actuate the second active valve in a second predetermined manner during an expiratory phase of the patient's respiratory cycle, wherein the controller is structured to actuate the first active valve in a third predetermined manner and actuate the second active valve in a fourth predetermined manner during an inspiratory phase of the patient's respiratory cycle,wherein the actuation in the first predetermined manner opens the first active valve, wherein the actuation in the second predetermined manner closes the second active valve, wherein the actuation in the third predetermined manner closes the first active valve, and wherein the actuation in the fourth predetermined manner opens the second active valve, andwherein the first control chamber further includes a third flow regulating mechanism to selectively or constantly couple the first control chamber to atmosphere and the second control chamber further includes a fourth flow regulating mechanism structured to selectively or constantly couple the second control chamber to atmosphere,wherein the first conduit is fluidly coupled to the first control chamber and the second conduit is fluidly coupled to the second control chamber, andwherein the first control chamber is fluidly coupled between the first conduit and the common chamber and is structured to receive breathing gas from the pressure source via the first conduit and the second control chamber is fluidly coupled between the second conduit and the common chamber and is structured to receive breathing gas from the pressure source via the second conduit. 2. The respiratory interface apparatus according to claim 1, wherein the patient contacting portion is part of a mask body, and wherein the common chamber, the first control chamber and the second control chamber are coupled to the mask body and together form a patent interface assembly. 3. The respiratory interface apparatus according to claim 1, wherein the pressure source is structured to generate a flow of breathing gas, the first conduit and the second conduit being fluidly coupled to the pressure source. 4. The respiratory interface apparatus according to claim 3, wherein the pressure source includes a pressure generator. 5. The respiratory interface apparatus according to claim 4, wherein the controller is structured to actuate the first active valve in the first predetermined manner and actuate the second active valve in the second predetermined manner during the expiratory phase of the patient's respiratory cycle to enable exhaust flow from the patient to be vented to the first conduit and to prevent a predetermined amount of the patient exhaust flow from entering the second conduit, and wherein the controller is structured to actuate the first active valve in the third predetermined manner and actuate the second active valve in the fourth predetermined manner during the inspiratory phase of the patient's respiratory cycle to prevent a predetermined amount of CO2 from flowing into the common chamber from the first conduit and to enable gas provided by the pressure source to flow into the common chamber from the second conduit. 6. The respiratory interface apparatus according to claim 1, wherein the third flow regulating mechanism is a third active valve controlled by the controller and the fourth flow regulating mechanism is a fourth active valve controlled by the controller, wherein the controller is structured to actuate the third active valve in a fifth predetermined manner and actuate the fourth active valve in a sixth predetermined manner during the expiratory phase of the patient's respiratory cycle, and wherein the controller is structured to actuate the third active valve in a seventh predetermined manner and actuate the fourth active valve in an eighth predetermined manner during the inspiratory phase of the patient's respiratory cycle. 7. The respiratory interface apparatus according to claim 6, wherein the respiratory interface apparatus includes one or more sensors operatively coupled to the controller, and wherein the controller controls one or more of the first, second, third and fourth active valves based on an output of the one or more sensors. 8. The respiratory interface apparatus according to claim 7, wherein the one or more sensors sense one or more of pressure, CO2 level, O2 level and flow rate. 9. The respiratory interface apparatus according to claim 3, wherein the third flow regulating mechanism and the fourth flow regulating mechanism are passive. 10. The respiratory interface apparatus according to claim 9, wherein the third flow regulating mechanism and the fourth flow regulating mechanism are each one of a one-way passive valve, a fixed leak port, and a fixed resistance port. 11. A system of enabling determination of one or more sleep phenotyping parameters of a subject including the respiratory interface apparatus according to claim 1.
