Abstract

Disclosed is a nasal ventilation mask having separate ports to monitor end-tidal CO 2 expulsion integrated into the mask in order to monitor end-tidal CO 2 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, the mask including a CO 2 absorber for eliminating at least in part rescuer's exhaled CO 2 delivered to the victim.

Claims (20)

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, the 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 and isolated from the nasal cavity, 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 the exterior opening is adapted to scavenge gases expelled orally by a wearer.

2. The mask of claim 1 , wherein the mask is adapted for use as an oxygen transport mask, or as a ventilation mask providing O2 and anesthesia gases.

3. The mask of claim 1 , wherein the mask is adapted for CPAP pre-operatively, intra-operatively, and/or post-operatively.

4. The mask of claim 1 , wherein the mask is adapted for connection to a resuscitator bag such that a patient's mouth and airway are not obstructed by the resuscitator bag, to allow for direct laryngoscopy and intubation.

5. The mask of claim 1 , wherein the mask comprises a gas channel inside the nasal cavity, wherein the gas channel fluidly couples the end-tidal CO2 port to the exterior opening and is configured to isolate orally expelled gases from a rest of the cavity.

6. The mask of claim 1 , wherein the mask comprises a gas monitoring attachment.

7. The mask of claim 6 , wherein the gas monitoring attachment is integral to or attached to the ventilation port.

8. The mask of claim 1 , further comprising an anesthesiologist controlled 2-way, 3 port valve permitting an anesthesiologist to switch between separately monitoring nasal and oral end-tidal CO2, or simultaneously monitoring nasal and oral end-tidal CO2, wherein when oral end-tidal CO2 monitoring is chosen, ventilation gases expelled orally by the patient are also monitored.

9. The mask of claim 1 , wherein the mask comprises a scavenger line configured to for diverting at least a portion of the scavenged gas to an end-tidal CO2 monitor.

10. The mask of claim 9 , wherein a connector is provided where the monitoring line intercepts the scavenger line, diverting gas flow, resulting in a positive pressure relative to the monitoring line, to permit gases to be sampled from the scavenger line.

11. A nasal ventilation mask comprising a body defining a nasal cavity having an interior configured to cover a patient's nose while leaving a patient's mouth uncovered, the mask having a first port fluidly coupled to the nasal cavity and configured for introducing oxygen into the nasal cavity, a second port fluidly coupled to the nasal cavity and configured for directing a gas toward or away from the nasal cavity, and a third port fluidly coupled to an exterior opening under a nose region of the mask, wherein the exterior opening is isolated from the nasal cavity and is adapted to overlie a patient's lip region, and the third port is configured to couple with a monitoring line, the second port is configured to couple with a ventilation line that is different than the monitoring line, and the exterior opening is adapted to scavenge gases expelled orally by a wearer.

12. The mask of claim 11 , wherein the mask comprises a gas channel inside the nasal cavity, wherein the gas channel fluidly couples the third port to the exterior opening.

13. The mask of claim 11 , wherein the mask comprises a gas monitoring attachment.

14. The mask of claim 13 , wherein the gas monitoring attachment is integral to or attached to the second port.

15. The mask of claim 11 , further comprising an anesthesiologist controlled 2-way, 3 port valve permitting an anesthesiologist to switch between separately or simultaneously monitoring any of the first, second, and third ports.

16. 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, the anesthesia mask having a first port, a second port, and a third port, and a scavenger system, the first port fluidly coupled to the nasal cavity and configured for introducing oxygen into the nasal cavity, the second port fluidly coupled to the nasal cavity and configured for directing a gas toward or away from the nasal cavity, and the third port coupled to an exterior opening under a nose region of the mask and adapted to overlie a patient's lip region, and the scavenger system configured for collecting anesthetic gases that may leak out around a mouth and nose of a patient, the scavenger system comprising the third port and a gas hood, the 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 third port is configured to couple with a monitoring line, and the second port is configured to couple with a ventilation line that is different than the monitoring line.

17. The mask of claim 16 , wherein the mask comprises a gas channel inside the nasal cavity, wherein the gas channel fluidly couples the third port to the exterior opening.

18. The mask of claim 16 , wherein the mask comprises a gas monitoring attachment.

19. The mask of claim 18 , wherein the gas monitoring attachment is integral to or attached to the second port.

20. The mask of claim 16 , further comprising an anesthesiologist controlled 2-way, 3 port valve permitting an anesthesiologist to switch between separately or simultaneously monitoring any of the first, second, and third ports.
