Abstract
A nasopharyngeal airway device is provided to be used in conjunction with an oxygen source and a capnometer. In one or more non-limiting embodiments, the nasopharyngeal airway device provides adequate oxygen delivery and monitors capnography output more efficiently. The device includes a nasal trumpet having one or more lumens, and a nasal cannula having a tube portion and at least two prongs. A first prong is insertable into a nasal cavity of a human subject, wherein the remaining prongs are equal in number to a number of one or more lumens of the nasal trumpet. The remaining prongs are adjacent to each other on the tube portion and configured to snugly fit into the nasal trumpet. The gases may pass into the nasal cannula from their respective ends into the prongs which may be separated by a single closure in the cannula so as to prevent the mixture of gasses.
