14. The mask of claim 1 , wherein removal of the front portion from the frame portion does not separate the gas delivery orifice from the respiratory opening region.
15. A mask for patient ventilation comprising:
a frame portion for surrounding a respiratory opening region of a patient;
a front portion removably coupled with said frame portion and configured for covering said respiratory opening region;
a retention strap for maintaining positive pressure between the frame portion and said patient;
a plurality of gas delivery orifices directly coupled with and on a first side of said frame portion and configured such that that each of said plurality of gas delivery orifices is lateral to said front portion;
a gas evacuation orifice directly coupled with and on a second side, opposite the first side, of said frame portion lateral to said front portion;
wherein, when the mask is positioned on the patient, the plurality of gas delivery orifices directs a cross-flow of gas from the first side of the frame to the second side of the frame across the respiratory opening region of the patient, and wherein removal of the front portion from the frame portion provides unobstructed access to said respiratory opening region and does not separate the gas delivery orifice and gas evacuation orifice from the frame, such that the cross-flow of gas is maintained when the front portion is removed from the frame portion.
16. The mask of claim 15 further comprising:
a gas limb coupled with at least one of said gas delivery orifices for providing gas flow to said respiratory opening region of said patient.
17. The mask of claim 16 , wherein said gas limb comprises a plurality of tubes.
18. The mask of claim 16 wherein said gas limb is adapted to be disposed laterally with respect to a temporal region on the head of the patient.
19. The mask of claim 16 wherein said gas limb is parallel with at least a portion of said retention strap.
20. The mask of claim 16 wherein said gas limb is coupled with at least a portion of said retention strap.
21. The mask of claim 16 wherein said gas limb is swivelably coupled with said at least one gas delivery orifice.
22. The mask of claim 16 wherein said gas limb is coupled with said frame portion such that said positive pressure between said frame portion and said patient is evenly distributed.
23. The mask of claim 16 wherein at least one of said gas delivery orifices is configured to provide said gas flow across said respiratory opening region.
24. A mask for patient ventilation comprising:
a frame portion for surrounding a nose and mouth of a patient;
a front removable portion coupled with said frame portion and configured for covering said nose and mouth, wherein access to said nose and mouth is unobstructed upon removal of said front portion;
a retention strap for maintaining positive pressure between the frame portion and the patient;
