Ventilation mask
First Claim
1. A nasal ventilation mask having a body defining a nasal cavity having an interior configured to cover a patient'"'"'s nose while leaving a patient'"'"'s mouth uncovered, said mask having an O2 port, a ventilation port, and an end-tidal CO2 port, the O2 port fluidly coupled to the nasal cavity for introducing oxygen into the nasal cavity, the ventilation port fluidly coupled to the nasal cavity for directing a gas toward or away from the nasal cavity, and the end-tidal CO2 port fluidly coupled to an exterior opening under a nose region of the mask, adapted to overlie a patient'"'"'s lip region, wherein the end-tidal CO2 port is configured to couple with a monitoring line, and the ventilation port is configured to couple with ventilation line that is different than the monitoring line, and said exterior opening is adapted to scavenge gases expelled orally by a wearer, and an integrated end-tidal CO2 monitor for monitoring end-tidal CO2 expelled nasally and orally by a patient.

Abstract
Disclosed is a nasal ventilation mask having separate ports to monitor end-tidal CO2 expulsion integrated into the mask in order to monitor end-tidal CO2 expelled nasally or orally. Also disclosed is a CPR mask for nose-to-mouth and/or mouth-to-mouth resuscitation, having a body shaped to cover the nose and/or mouth of a victim, said mask including a CO2 absorber for eliminating at least in part rescuer'"'"'s exhaled CO2 delivered to the victim.

- 1. A nasal ventilation mask having a body defining a nasal cavity having an interior configured to cover a patient'"'"'s nose while leaving a patient'"'"'s mouth uncovered, said mask having an O2 port, a ventilation port, and an end-tidal CO2 port, the O2 port fluidly coupled to the nasal cavity for introducing oxygen into the nasal cavity, the ventilation port fluidly coupled to the nasal cavity for directing a gas toward or away from the nasal cavity, and the end-tidal CO2 port fluidly coupled to an exterior opening under a nose region of the mask, adapted to overlie a patient'"'"'s lip region, wherein the end-tidal CO2 port is configured to couple with a monitoring line, and the ventilation port is configured to couple with ventilation line that is different than the monitoring line, and said exterior opening is adapted to scavenge gases expelled orally by a wearer, and an integrated end-tidal CO2 monitor for monitoring end-tidal CO2 expelled nasally and orally by a patient.

9. An anesthesia mask having a body defining a nasal cavity having an interior configured to cover a patient'"'"'s nose while leaving a patient'"'"'s mouth uncovered, said anesthesia mask having an O2 port, a ventilation port, an end-tidal CO2 port, and a built in scavenger system, the scavenger system configured for collecting anesthetic gases that may leak out around a mouth and nose of a patient, and comprising the end-tidal CO2 port fluidly coupled to an exterior opening under a nose region of the anesthesia mask and adapted to overlie a patient'"'"'s lip region, and a gas hood located under the nose region of the anesthesia mask and extending from an outer surface of the anesthesia mask around the exterior opening to enhance the collection of anesthetic gases around the patient'"'"'s mouth, wherein the end-tidal CO2 port is configured to couple with a monitoring line, and the ventilation port is configured to couple with ventilation line that is different than the monitoring line.

10. A method for ventilating a patient, comprising:
-
supplying a nasal ventilation mask having a body defining a nasal cavity having an interior configured to cover a patient'"'"'s nose while leaving a patient'"'"'s mouth uncovered, said mask having an O2 port, a ventilation port, and an end-tidal CO2 port, the O2 port fluidly coupled to the nasal cavity for introducing oxygen into the nasal cavity, and the end-tidal CO2 port fluidly coupled to an exterior opening under a nose region of the mask, wherein the end-tidal CO2 port is configured to couple with a monitoring line, and the ventilation port is configured to couple with a ventilation line that is different than the monitoring line, and an integrated end-tidal CO2 monitor for monitoring end-tidal CO2 expelled nasally and orally; positioning the mask over the patient'"'"'s nose above a patient'"'"'s lip region, introducing oxygen into the nasal cavity, and allowing gases expelled orally by the patient to be scavenged, and collecting and monitoring end-tidal CO2 expelled by the patient. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method for ventilating a patient, comprising:
-
providing an anesthesia mask having a body defining a nasal cavity having an interior configured to cover a patient'"'"'s nose while leaving a patient'"'"'s mouth uncovered, said mask having an O2 port, a ventilation port, and an end-tidal CO2 port, the O2 port fluidly coupled to the nasal cavity for introducing oxygen into the nasal cavity, and a built in scavenger system for collecting anesthetic gases that may leak out around the mouth and nose of the patient, and comprising the end-tidal CO2 port fluidly coupled to an exterior opening under a nose region of the anesthesia mask and adapted to overlie a patient'"'"'s lip region; coupling a monitoring line to the end-tidal CO2 port, and coupling a ventilation line to the ventilation port, wherein the monitoring line is different than the ventilation line; and holding the mask in place over the nose of the patient using one or more head straps, introducing oxygen into the interior of the mask, and collecting said leaked gases, and monitoring said collected gases.
