The present invention relates to a method and a system for controlling breathing of a patient. A system for controlling breathing of a patient includes a respiratory conduit. The respiratory conduit is configured to be coupled to a patient interface device and is further configured to be coupled to a pressurized air generating device. The respiratory conduit includes at least two air flow control devices, positioned between the patient interface device and the pressurized air generating device. The respiratory conduit includes at least two volumes, wherein one volume is positioned between a first air flow control device and a second air flow control device and another volume is positioned between a second air flow control device and a third air flow control device.

What is claimed: 1. A system for controlling breathing of a patient, comprising:a respiratory conduit;said respiratory conduit is configured to be coupled to a patient interface device;said respiratory conduit is further configured to be coupled to a pressurized air generating device;said respiratory conduit includes a first, second, and third air flow control devices, positioned between said patient interface device and said pressurized air generating device, each of said air flow control devices defines an orifice being in communication with ambient air; andsaid respiratory conduit includes at least two volumes, wherein one volume is positioned between said first air flow control device and said second air flow control device and a second volume is positioned between said second air flow control device and said third air flow control device;wherein said volumes are partial dead space volumes configured to accumulate at least a portion of breath expired by the patient;wherein said first, second, and third air flow control devices are configured to control a rate of excretion of carbon dioxide from said respiratory conduit and a concentration of said carbon dioxide in blood of the patient; andwherein said second airflow control device comprises an internal conduit being disposed within said second volume in a substantially coaxial configuration, said internal conduit defining multiple openings along a longitudinal axis, said internal conduit being coupled to a valve that is configured to control evacuation of carbon dioxide from within said second volume to the ambient air.
