Ventilation mask

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, the mask including a CO2 absorber for eliminating at least in part rescuer's exhaled CO2 delivered to the victim.

What is claimed is: 
     
         1 . A nasal ventilation mask comprising:
 a body having an interior forming a nasal cavity, a gas channel, and an exterior opening, wherein the nasal cavity is configured to cover a nose of a patient while leaving a mouth of the patient uncovered and the gas channel is separated from the nasal cavity;   an O 2  port fluidly coupled to the nasal cavity and configured for introducing oxygen into the nasal cavity;   a ventilation port fluidly coupled to the nasal cavity and configured for directing a gas toward or away from the nasal cavity; and   an end-tidal CO 2  port fluidly coupled to the exterior opening through the gas channel of the body,   wherein the exterior opening is adapted to scavenge a gas expelled orally by a wearer, and the gas channel is configured to direct the gas expelled orally from the exterior opening to the end-tidal CO 2  port.   
     
     
         2 . The nasal ventilation mask of  claim 1 , comprising a gas hood located under a nose region of the mask and extending from an outer surface of the mask around the exterior opening to enhance the collection of anesthetic gases around the mouth of the patient. 
     
     
         3 . The nasal ventilation mask of  claim 1 , wherein the end-tidal CO 2  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. 
     
     
         4 . The nasal ventilation mask of  claim 1 , wherein the gas channel is configured to isolate the gas expelled orally from the nasal cavity. 
     
     
         5 . The nasal ventilation mask of  claim 1 , wherein the gas channel is configured to direct a gas expelled nasally toward the end-tidal CO 2  port. 
     
     
         6 . The nasal ventilation mask of  claim 1 , wherein the mask comprises a gas monitoring attachment. 
     
     
         7 . The nasal ventilation mask of  claim 1 , further comprising a removable cap configured to be coupled to and obstruct the O 2  port. 
     
     
         8 . The nasal ventilation mask of  claim 1 , further comprising tabs or eyelets for attaching the mask anteriorly with a mask anchor, or posteriorly with a traditional anesthesia mask strap. 
     
     
         9 . The nasal ventilation mask of  claim 1 , wherein the gas channel extends inside of the nasal cavity. 
     
     
         10 . The nasal ventilation mask of  claim 1 , wherein a periphery of the body comprises a resiliently deformable material. 
     
     
         11 . A nasal ventilation mask comprising:
 a body having an interior forming a nasal cavity, a gas channel, and an exterior opening, wherein the nasal cavity is configured to cover a nose of a patient while leaving a mouth of the patient uncovered and the gas channel is separated from the nasal cavity;   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 exterior opening through the gas channel of the body, and configured for coupling with a monitoring line;   wherein the exterior opening is adapted to scavenge a gas expelled orally by a wearer, and the gas channel is configured to direct the gas from the exterior opening to the third port.   
     
     
         12 . The nasal ventilation mask of  claim 11 , comprising a gas hood located under a nose region of the mask and extending from an outer surface of the mask around the exterior opening to enhance the collection of anesthetic gases around the mouth of the patient. 
     
     
         13 . The nasal ventilation mask of  claim 11 , wherein the second port is configured to couple with a ventilation line that is different than the monitoring line. 
     
     
         14 . The nasal ventilation mask of  claim 11 , wherein the gas channel is configured to isolate the gas expelled orally from the nasal cavity. 
     
     
         15 . The nasal ventilation mask of  claim 11 , wherein the gas channel is configured to direct a gas expelled nasally toward the third port. 
     
     
         16 . The nasal ventilation mask of  claim 11 , wherein the mask comprises a gas monitoring attachment. 
     
     
         17 . The nasal ventilation mask of  claim 11 , further comprising a removable cap configured to be coupled to and obstruct the first port. 
     
     
         18 . The nasal ventilation mask of  claim 11 , further comprising tabs or eyelets for attaching the mask anteriorly with a mask anchor, or posteriorly with a traditional anesthesia mask strap. 
     
     
         19 . The nasal ventilation mask of  claim 11 , wherein the gas channel extends inside of the nasal cavity. 
     
     
         20 . The nasal ventilation mask of  claim 11 , wherein a periphery of the body comprises a resiliently deformable material.
