Abstract:
1. An apparatus for measuring respiratory pressure from the nasal passageways of a patient and insufflating a treating gas into the nostrils of a patient, the apparatus comprising: a) a gas receiving hollow body; b) a pressure transducer for measuring pressure fluctuations in said hollow body; c) a treatment gas supply connected via a first conduit to said hollow body to provide a supply of treatment gas to the interior of said hollow body; d) a carbon dioxide monitor connected to said hollow body via a second conduit, for aspirating and receiving gases exhaled from the nostrils of a patient; e) a first hollow prong having a fixed length, a distal end of said first hollow prong being open and sized to be received within a first nasal passageway and a proximal end of said first hollow prong being connected to said hollow body to provide fluid communication to said hollow body and to said pressure transducer; f) a second hollow prong having a fixed length, a distal end of said second hollow prong being open and sized to be received within a second nasal passageway and a proximal end of said second hollow prong being connected to said hollow body to provide fluid communication to said hollow body; and g) means to selectively inject said treatment gas into said hollow body or withdraw exhaled gases for analysis from said hollow body while simultaneously measuring pressure fluctuations in said hollow body.
