Abstract

A method for ventilating a patient in which nasal mask having an exhalation scoop formed of a flexible or resiliently deformable material, fixed adjacent a lower portion of mask, is positioned to overlie an upper lip of a patient. When needed, the exhalation scoop is folded back on itself to provide access to the patient'"'"'s mouth.

Claims

1. A method for ventilating a patient, comprising

providing a nasal mask having an exhalation scoop formed of a flexible or resiliently deformable material, fixed adjacent a lower portion of the mask, and adapted to overlie an upper lip of the patient when the mask is worn, and when needed, folding the exhalation scoop back on itself to provide access to the patient'"'"'s mouth.

2. The method of claim 1, further including monitoring end-tidal CO₂ by sampling exhaled CO₂ expelled from the mouth and/or nose of the patient via an end-tidal CO₂ port.

3. The method of claim 1, further including attaching the mask to an anesthesia machine, ventilation machine, hyperinvation bag or a ventilation or gas accessory.

4. The method of claim 1, further including attaching the mask to an oxygen source for supplying oxygen to an interior of the mask.

5. The method of claim 1, wherein the exhalation scoop is formed of a flexible or resiliently deformable material having a Shore A Hardness durometer selected from 2-10.

6. The method of claim 1, wherein the exhalation scoop is formed of a flexible or resiliently deformable material having a Shore A Hardness durometer of about 5.

7. The method of claim 1, wherein the exhalation scoop is formed of a flexible or resiliently deformable material having a Shore A Hardness durometer of 3-7.
