An oral cannula for placement within the oral cavity of a patient for delivery of a treatment gas and for collecting end-tidal carbon dioxide (ETCO) includes a treatment gas delivery lumen including at least one aperture near a distal end of the treatment gas delivery lumen; an end-tidal COsampling lumen. The cannula also includes a cap having (i) a gas diverter adapted for diverting at least a portion of the treatment gas and (ii) an end-tidal COinlet including flutes and apertures there between that are in communication with the end-tidal COsampling lumen. The oral cannula is adapted for custom bending or has a bend such that the oral cannula is insertable and retainable in a patient's mouth and functional for supplying a treatment gas and sampling gas exhaled by the patient.

Oral cannula

An oral cannula for delivering oxygen and sampling end-tidal carbon dioxide includes an oxygen supply lumen having plural outlets and an end-tidal carbon dioxide (ETCO2) lumen having an inlet. The ETCO2 lumen and oxygen supply lumen form a unitary oral cannula such that the oxygen supply lumen outlet is spaced apart from the ETCO2 lumen inlet. The oral cannula is adapted for bending or has a bend such that the oral cannula is insertable and retainable in a patient's mouth.
