Lateral gas line configuration

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.

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;
• a gas delivery orifice coupled with and on a first side of said frame portion and configured such that said gas delivery orifice is lateral to said front removable 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 removable portion;
• wherein, when the mask is positioned on the patient, the gas delivery orifice directs a cross-flow of gas from the first side of the frame to the second side of the frame across the nose and mouth of the patient, and wherein removal of the front portion from the frame portion provides unobstructed access to said nose and mouth and does not separate the gas delivery orifice and gas evacuation orifice from the frame.

A mask for patient ventilation comprising:

• a frame portion for surrounding a nose and mouth of a patient;
• a front portion removably 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;
• a first gas delivery limb coupled with a first side region of said frame portion;
• and
• a second gas limb coupled with a second side region of said frame portion such that said first gas delivery limb and said second gas limb are bilateral and configured to be disposed in a parallel configuration with respect to the temporal regions of the patient, said second gas limb configured to evacuate gas from the mask;
• wherein the first gas delivery limb is configured to deliver and direct a cross-flow of gas, across the nose and mouth of the patient, from the first side region of said frame portion to the second gas limb when the front portion is removed from the frame portion.
