Ventilation mask

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, said mask including a CO 2 absorber for eliminating at least in part rescuer's exhaled CO 2 delivered to the victim.

1 - 13 . (canceled) 
     
     
         14 . A nasal ventilation mask having tabs or eyelets for attaching the mask anteriorly with a mask anchor, or posteriorly with a traditional anesthesia mask strap, said mask characterized by one or both of the following features:
 (a) adapted to accommodate a combined anterior-posterior head strap attached to the mask alone, or to the mask and a support surface, to hold a patient's head and/or neck against movement; and   (b) adapted to secure a patient's head with a head strap to a support surface, wherein the patient's head and the support surface remain in a desired position even when a provider changes the patient's head and/or neck angles.   
     
     
         15 . A nasal mask, wherein the mask is usable as an oxygen transport mask or as a ventilation mask for providing O 2  and anesthesia gases, and for monitoring end-tidal CO 2 . 
     
     
         16 . The mask of  claim 15 , said mask having one or more ports for monitoring end-tidal CO 2 , wherein the mask is adapted for use for CPAP pre-operatively, intra-operatively, and/or post-operatively. 
     
     
         17 . The mask of  claim 15 , said mask having ports for monitoring end-tidal CO 2 , wherein the mask is adapted to be connected to a resuscitator bag such that a patient's mouth and airway are not obstructed by the resuscitator bag, whereby to allow for direct laryngoscopy and intubation. 
     
     
         18 . The mask of  claim 15 , wherein the mask is attachable anteriorly with a mask anchor, or posteriorly with a conventional anesthesia mask strap. 
     
     
         19 . The mask of  claim 15 , said mask having an O 2  port adapted for introduction of oxygen into the mask, a ventilation port and a gas monitoring attachment integral to or attached to the mask. 
     
     
         20 . The mask of  claim 15 , said mask having a built in scavenger system for collecting anesthetic gases that may leak out from around a patient's mouth and/or nose. 
     
     
         21 . The mask of  claim 15 , said mask having a chin strap adapted for application to a patient's submental space, attached to said mask, for applying pressure to force a patient's tongue against the patient's soft palate and induce an obstruction of the retro-glossal space, whereby to reduce or prevent leakage of gases out of the patient's mouth and allow the patient to breathe out the nose, wherein the chin strap is adapted to release pressure, if needed, during exhalation to prevent an expiratory obstruction. 
     
     
         22 . A CPR mask for nose-to-mouth and/or mouth-to-mouth resuscitation, comprising a body shaped to cover a nose and/or mouth of a patient, said mask including a CO 2  absorber for eliminating at least in part a rescuer's exhaled CO 2  delivered to the patient. 
     
     
         23 . The mask of  claim 22 , wherein the CO 2  absorber is coated on an inside surface of the mask. 
     
     
         24 . The mask of  claim 22 , wherein the mask further includes a ventilation tube, wherein the CO 2  absorber is located in the ventilation tube. 
     
     
         25 . The mask of  claim 24 , further including a biological filter, incorporated into the ventilation tube. 
     
     
         26 . The mask of  claim 22 , further including a one-way valve. 
     
     
         27 . The mask of  claim 22 , including straps adapted for holding the mask to a head of the patient. 
     
     
         28 . The mask of  claim 22 , wherein the mask further includes a compliant periphery adapted to conform to a face of the patient, wherein the periphery includes a soft, compliant air bladder or a resiliently deformable foam cushion. 
     
     
         29 . The mask of  claim 22 , further including a biological filter incorporated into an inside of the mask. 
     
     
         30 . A method for ventilating a patient, comprising:
 supplying a nasal ventilation mask having tabs or eyelets for attaching the mask anteriorly with a mask anchor, or posteriorly with a traditional anesthesia mask strap, said mask having a combined anterior-posterior head strap, where the posterior head strap is adapted to attach to the mask alone, or to attach to the mask and a support surface;   positioning the mask on a patient's head; and   securing the patient's head with the head strap to the support surface, whereupon the patient's head is maintained in a desired position relative to the support surface even when the provider changes the head and/or neck angles.   
     
     
         31 . A method for providing nose-to-mouth and/or mouth-to-mouth resuscitation, comprising:
 providing a ventilation mask having a body shaped to cover the nose and/or mouth of a patient, said mask including a CO 2  absorber for eliminating at least in part a rescuer's exhaled CO 2  delivered to the patient;   positioning the mask on a head of the patient in need of resuscitation; and   administering resuscitation to the patient.   
     
     
         32 . The method of  claim 31 , wherein the CO 2  absorber is coated on an inside surface of the mask. 
     
     
         33 . The method of  claim 31 , wherein the mask further includes a ventilation tube, wherein CO 2  absorber is located in the ventilation tube. 
     
     
         34 . The method of  claim 33 , wherein a biological filter is incorporated into the mask or a ventilation tube for the mask. 
     
     
         35 . The method of any of  claim 31 , wherein the mask further includes a one-way valve. 
     
     
         36 . The method of  claim 31 , wherein the mask includes straps adapted for holding the mask to the head of a patient. 
     
     
         37 . The method of  claim 31 , wherein the mask further includes a compliant periphery adapted to conform to a face of the patient, wherein the periphery includes a soft, compliant air bladder or a resiliently deformable foam cushion.
