Claims
- 1. A face mask assembly, comprising:
a face mask sized and configured to substantially conformally fit over the oral and nasal region of a patient's face, the mask having a port; a gas measurement component having a proximal end operably coupled to the face mask through the port; and an oxygen delivery housing in communication with a distal end of the gas measurement component, the oxygen delivery housing defining a reservoir and including an oxygen delivery inlet port opening into a side of the housing.
- 2. The face mask assembly of claim 1, wherein the gas measurement component is arranged as a mainstream adapter.
- 3. The face mask assembly of claim 1, wherein the gas measurement component comprises a gas sample cell.
- 4. The face mask assembly of claim 3, wherein the gas measurement component further comprises a gas sensor cooperatively coupled to the gas sample cell.
- 5. The face mask assembly of claim 1, wherein the reservoir is a fixed volume reservoir.
- 6. The face mask assembly of claim 5, wherein the oxygen delivery inlet port is located substantially medially along a length of the oxygen delivery housing.
- 7. The face mask assembly of claim 5, wherein the oxygen delivery inlet port is located relatively proximally along a length of the oxygen delivery housing.
- 8. The face mask assembly of claim 5, wherein the oxygen delivery inlet port is located relatively distally along a length of the oxygen delivery housing.
- 9. The face mask assembly of claim 1, wherein the reservoir is an adjustable volume reservoir.
- 10. The face mask assembly of claim 9, wherein the oxygen delivery inlet port is located medially along a length of the oxygen delivery housing.
- 11. The face mask assembly of claim 9, wherein the oxygen delivery inlet port is located relatively proximally along a length of the oxygen delivery housing.
- 12. The face mask assembly of claim 9, wherein the oxygen delivery inlet port is located relatively distally along a length of the oxygen delivery housing.
- 13. The face mask assembly of claim 1, further including a flow measurement component operably interposed between the face mask and the oxygen delivery housing.
- 14. The face mask assembly of claim 13, wherein the flow measurement component is integral with the gas measurement component.
- 15. The face mask assembly of claim 1, further including a tubular adapter piece comprising a base leg and two side legs in common communication, the tubular adapter in communication with a distal end of the gas measurement component, a first side leg having a check valve therein oriented to permit proximal flow and to prevent distal flow therethrough, the first side leg having a distal end in communication with a proximal end of the oxygen delivery housing, and a second side leg having a check valve therein oriented to permit distal flow and to prevent proximal flow therethrough, the second side leg having a distal end in communication with the ambient atmosphere.
- 16. The face mask assembly of claim 15, wherein the tubular adapter piece is configured as at least one of a Y and a T.
- 17. The face mask assembly of claim 1, wherein the gas sample component is arranged as a sidestream adapter.
- 18. The face mask assembly of claim 1, further including structure for securing the face mask over the oral and nasal region of the patient's face.
