A system for diagnosis and treatment of breathing disorders in a patient, comprises a flow generator supplying an air flow to an airway of a patient via a flow path, a venting arrangement moveable between (i) a closed position in which the flow path is substantially sealed between the flow generator and the patient's airway and (ii) an open position in which the flow path is open to an ambient atmosphere, a sensor detecting data corresponding to flow through the patient's airway, and a processing arrangement controlling operation of the venting arrangement and the flow generator, wherein, in a diagnostic mode, the processing arrangement maintains the venting arrangement in the open position and in a therapeutic mode, the processing arrangement maintains the venting arrangement in the closed position and controls the flow generator to supply to the patient's airway via the flow path a calculated therapeutic pressure.

1. A system for diagnosis and treatment of breathing disorders in a patient, comprising: a flow generator supplying an airflow to an airway of a patient via an air flow path;a venting arrangement moveable between (i) a closed position in which the flow path is substantially sealed from an ambient atmosphere between the flow generator and the patient's airway, and (ii) an open position in which the flow path is open to the ambient atmosphere;a sensor detecting data corresponding to flow through the patient's airway; anda processing arrangement controlling operation of the venting arrangement and the flow generator,wherein, in a diagnostic mode, the processing arrangement maintains the venting arrangement in the open position and monitors airflow through the patient's airway using the data provided by the sensor, andwherein, in a therapeutic mode, the processing arrangement maintains the venting arrangement in the closed position and controls the flow generator to supply to the patient's airway via the flow path a therapeutic pressure calculated based on the data compiled in the diagnostic mode. 2. The system according to claim 1, further comprising a tube and a mask coupled to the flow generator. 3. The system according to claim 2, wherein the sensor includes a pressure sensor sensing pressure in the mask. 4. The system according to claim 1, wherein the venting arrangement allows a leak from the flow path sufficient to prevent CO2 buildup. 5. The system according to claim 1, wherein the diagnostic mode is initiated by one of the patient and an operator. 6. The system according to claim 1, wherein the diagnostic mode is automatically initiated by the processing arrangement. 7. The system according to claim 1, wherein, upon predetermined criteria, the diagnostic mode switches to the therapeutic mode. 8. The system according to claim 7, wherein the predetermined criteria is one of (i) a predetermined time, (ii) a value corresponding to flow limitation events, (iii) when the therapeutic pressure is determined in the diagnostic mode, (iv) patient-determined and (v) operator-determined. 9. The system according to claim 8, wherein the predetermined time is a predetermined portion of at least one sleep cycle of the patient. 10. The system according to claim 8, wherein the predetermined time is at least one sleep cycle of the patient. 11. The system according to claim 8, wherein the value corresponding to flow limitation events is one of a predetermined number of flow limitation events and an obstruction index. 12. The system according to claim 1, wherein, in the therapeutic mode, the processing arrangement controls the flow generator to supply the therapeutic pressure based on a plurality of data measurements compiled from multiple diagnostic sessions. 13. A method for diagnosis and treatment of breathing disorders in a patient, comprising the steps of: initiating a diagnostic mode in which a processing arrangement controls a venting arrangement to an open position in which a flow path between the flow generator and the patient's airway is open to an ambient atmosphere;detecting, with a sensor, data corresponding to flow through the patient's airway;monitoring airflow through the patient's airway using data provided by the sensor;upon a predetermined criteria, initiating a therapeutic mode in which the processing arrangement switches the venting arrangement into the closed position and controls the flow generator to supply to the patient's airway via the flow path a therapeutic pressure calculated based on the data compiled in the diagnostic mode. 14. The method according to claim 13, further comprising a tube and a mask coupled to the flow generator. 15. The method according to claim 13, wherein the sensor includes a pressure sensor sensing pressure in the mask. 16. The method according to claim 13, wherein the venting arrangement allows a leak from the flow path sufficient to prevent CO2 buildup. 17. The method according to claim 13, wherein the diagnostic mode is initiated by one of the patient and an operator. 18. The method according to claim 13, wherein the predetermined criteria is one of (i) a predetermined time, (ii) a value corresponding to flow limitation events, (iii) when the therapeutic pressure is determined in the diagnostic mode, (iv) patient-determined and (v) operator-determined. 19. The method according to claim 18, wherein the predetermined time is a predetermined portion of at least one sleep cycle of the patient. 20. The method according to claim 18, wherein the predetermined time is at least one sleep cycle of the patient. 21. The method according to claim 18, wherein the value corresponding to flow limitation events is one of a predetermined number of flow limitation events and an obstruction index. 22. The system according to claim 1, wherein when the venting arrangement is in the closed position, the flow path is sealed from the ambient atmosphere between the flow generator and the patient's airway.
