1. An oral/nasal gas sampling and oxygen delivery manifold for sampling exhaled breath of a subject and delivering supplemental oxygen, comprising:

  • a main body portion having formed therein a suction port which is dimensioned and adapted to be connected with a collection tube to a suction device for sampling of exhaled breath of said subject;

    a nasal prong protruding from said main body portion and positioned for insertion into a nostril of said subject to collect nasally exhaled breath of said subject, and having a straight passage in fluid flow communication with a conduit passage of said suction port; and

    an oral prong protruding from said main body portion and having a straight conduit passage with a distal opening positioned for placement near an oral cavity of said subject to collect orally exhaled breath of said subject, and in fluid flow communication with the conduit passage of said suction port;

    the straight passage of said nasal prong connected to and aligned in the same plane as the straight conduit passage of said oral prong whereby the opposed nasal and oral passages are connected with said conduit passage of said suction port without any adjacent connected void volumes in any of said passages, and the pressure of the exhaled nasal and oral gases of said subject directly oppose each other in said straight aligned passages to provide optimal sampling of the said subjects exhaled gases for analysis.
