A medical mouthpiece may include a U-shaped first member having a tubular portion, the first member forming at least one lateral interocclusal passageway extending through the first member, and a second member received within the tubular portion. A medical breathing apparatus may include a U-shaped first member forming left and right lateral interocclusal passageways extending through the first member, a second member attached to the first member, and an adapter receivable within a tubular portion of the first member, wherein the adapter includes a respiratory orifice configured to deliver respiratory gas to the left and right lateral interocclusal passageways. A method for delivering positive pressure and/or a respiratory gas to a patient may include inserting a mouthpiece into a mouth of the patient, and delivering the positive pressure and/or the respiratory gas through the mouthpiece to a space adjacent a posterior oropharynx of the patient.

1. A medical mouthpiece, comprising: a generally U-shaped first member having a tubular portion extending anteriorly therefrom, the first member including an upper surface configured to contact an upper dentition of a patient spaced apart from a lower surface configured to contact a lower dentition
1. A medical mouthpiece, comprising: a generally U-shaped first member having a tubular portion extending anteriorly therefrom, the first member including an upper surface configured to contact an upper dentition of a patient spaced apart from a lower surface configured to contact a lower dentition of the patient;wherein the first member includes a posterior central orifice extending anteriorly to posteriorly through the first member along a medial line;wherein the first member forms at least one lateral interocclusal passageway extending anteriorly to posteriorly through the first member between the upper surface and the lower surface, the at least one lateral interocclusal passageway being configured to be positioned within a lateral interocclusal space of the patient; anda second member slidably received within the tubular portion, the second member including a perimeter ring defining an outwardly-facing surface configured to be in facing engagement with an inner surface of the tubular portion;wherein the second member includes an anterior central orifice extending anteriorly to posteriorly through the second member along the medial line, the anterior central orifice cooperating with the posterior central orifice to form a central passageway extending through the mouthpiece;wherein the second member includes one or more anterior apertures and at least one lateral passageway passing through the perimeter ring anteriorly to posteriorly from the one or more anterior apertures, the at least one lateral passageway of the second member being in fluid communication with the at least one lateral interocclusal passageway of the first member. 2. The medical mouthpiece of claim 1, wherein the second member includes a supplemental gas conduit providing fluid communication between a source of supplemental gas and a supply orifice in fluid communication with the at least one lateral interocclusal passageway of the first member. 3. The medical mouthpiece of claim 2, further comprising: a sampling port formed within a posterior portion of the at least one lateral interocclusal passageway of the first member; anda sampling conduit providing fluid communication between the sampling port and an analyzing apparatus configured to analyze respiratory gas. 4. The medical mouthpiece of claim 3, wherein the supply orifice is disposed anteriorly of the sampling port. 5. The medical mouthpiece of claim 3, further including a manifold coupled to the second member in fluid communication with the sampling conduit, the manifold including a first port configured to fluidly connect to the analyzing apparatus. 6. The medical mouthpiece of claim 3, wherein the sampling port includes a covering disposed thereon, the covering being impermeable to liquid and permeable to gas. 7. The medical mouthpiece of claim 1, wherein the at least one lateral interocclusal passageway of the first member includes a left lateral interocclusal passageway and a right lateral interocclusal passageway, the left and right lateral interocclusal passageways configured to be disposed on opposing sides of an oral cavity of the patient. 8. The medical mouthpiece of claim 1, wherein when the medical mouthpiece is positioned in a mouth of the patient, the one or more anterior apertures is positioned exterior to the mouth of the patient. 9. The medical mouthpiece of claim 1, further comprising a cheek flap having a retaining strap coupled thereto. 10. The medical mouthpiece of claim 9, wherein the cheek flap is slidably disposed about the tubular portion of the first member. 11. The medical mouthpiece of claim 9, wherein the first member includes a light emitting diode and the cheek flap includes a photodiode facing toward the light emitting diode. 12. The medical mouthpiece of claim 1, wherein the first member includes a temperature sensor. 13. A method for delivering a respiratory gas to a patient, the method comprising: inserting a mouthpiece according to claim 1 into a mouth of the patient; anddelivering the respiratory gas to the patient through the at least one lateral interocclusal passageway of the first member such that the respiratory gas is delivered through a posterior aperture to a space adjacent a posterior oropharynx of the patient. 14. The method of claim 13, wherein the second member includes a supplemental gas conduit in fluid communication with the at least one lateral interocclusal passageway of the first member, and the method further includes: delivering a supplemental gas through the supplemental gas conduit and into the at least one lateral interocclusal passageway of the first member, the supplemental gas mixing with the respiratory gas and being delivered to the posterior oropharynx. 15. The method of claim 13, wherein the first member includes a sampling port disposed within a posterior portion of the at least one lateral interocclusal passageway of the first member, and a sampling conduit fluidly connecting the sampling port to an analyzing apparatus, and the method further includes: collecting a sample of respiratory gas at the sampling port; andanalyzing the sample for partial pressure of carbon dioxide (CO2), oxygen (O2), nitrous oxide (N2O), or anesthetic gas. 16. The method of claim 15, further including: plotting the partial pressure of carbon dioxide (CO2), oxygen (O2), nitrous oxide (N2O), or anesthetic gas as a function of time or exhaled respiratory gas volume.
