A nasal ventilation interface comprising a hollow body having at least one and preferably two nasal apertures, and at least one and preferably two inhale apertures, and at least one and preferably two nasal insert tubes each associated with one of the nasal apertures and having an annular sleeve that forms a seal with a nostril of the patient. The hollow body has at least one and preferably two exhale apertures and at least one valve assembly associated with the exhale apertures that is capable of preventing air from passing through the exhale aperture upon the patient inhaling and allowing air to pass through the exhale aperture upon exhaling. The hollow body may also have at least one and preferably two filters for retaining heat and moisture from the exhale air and transferring the retained heat and moisture into the inhale air.

1. A nasal ventilation interface, comprising:a) at least one hollow body having at least one nasal aperture defined therein and at least one inhale aperture defined therein; b) at least one nasal insert tube associated with each nasal aperture of said body and capable of being inserted into a nostril of a patient, each nasal insert tube having at least one annular sleeve with a contact surface formed thereon and with a diameter that is greater than a diameter of said nasal insert tube, each annular sleeve contact surface capable of forming a seal with the nostril of the patient; c) at least one exhale aperture defined in said body and at least one valve assembly associated with said body, said at least one valve assembly being capable of preventing air from passing through said exhale aperture upon the patient inhaling and allowing air to pass through said exhale aperture upon exhaling; d) at least one first valve member having a first end and having a second end pivotally attached to a first inner wall of said body between said nasal aperture and said exhale aperture; and e) at least one second valve member having a first end and having a second end pivotally attached to a second inner wall of said body opposite said first inner wall and between said exhale aperture and said inhale aperture, said first valve member second end and said second valve member second end capable of abutting each other.
