A retention strap is coupled with the frame portion for maintaining positive pressure between the frame portion and the respiratory opening of the patient. A removable insert is configured to physically attach and detach from the frame portion without requiring removal of the frame or the retention strap from the patient. ## Claims ### Claim 1 A mask for patient ventilation comprising: a frame portion for surrounding a respiratory opening region of a patient; a retention strap configured to couple with the frame portion for maintaining positive pressure between the frame portion and the respiratory opening region of said patient; a removable insert that is configured to physically attach and detach from said frame portion without requiring removal of said retention strap or said frame portion from said patient; a breathing limb configured to couple with said frame portion, said breathing limb providing fresh respiratory gases to said patient; and wherein said breathing limb delivers said fresh respiratory gases to said patient with said removable insert removed from said frame portion. ### Claim 2 (depends on 1) The mask of claim 1 wherein said removable insert enables access to a nose region of said patient without requiring removal of said frame portion. ### Claim 3 (depends on 1) The mask of claim 1 wherein said removable insert enables access to a mouth region of said patient without requiring removal of said frame portion. ### Claim 4 (depends on 1) The mask of claim 1 wherein said removable insert enables access to a nose region of said patient without requiring removal of said retention strap. ### Claim 5 (depends on 1) The mask of claim 1 wherein said removable insert enables access to a mouth region of said patient without requiring removal of said retention strap. ### Claim 6 (depends on 1) The mask of claim 1 wherein the breathing limb is configured to couple with said removable insert. ### Claim 7 (depends on 1) The mask of claim 1 wherein said removable insert includes a self sealing port. ### Claim 8 (depends on 1) The mask of claim 1 wherein said removable insert includes a therapeutic device. ### Claim 9 (depends on 1) The mask of claim 1 wherein said removable insert is configured to provide a therapeutic function to said patient. ### Claim 10 (depends on 1) The mask of claim 1 wherein said removable insert is a different color than said frame portion. ### Claim 11 (depends on 1) The mask of claim 1 wherein said removable insert comprises an anti-fogging coating. ### Claim 12 (depends on 1) The mask of claim 1 wherein said removable insert is scented. ### Claim 13 (depends on 1) The mask of claim 1 wherein said removable insert comprises a graphic. ### Claim 14 A mask for patient ventilation comprising: a frame portion for surrounding a respiratory opening region of a patient; a semi-rigid retention strap configured for coupling with the frame portion for maintaining positive pressure between the frame portion and the respiratory opening region of the patient, said semi-rigid retention strap con- figured to maintain a head-shape when not disposed on said patient; a removable insert that is configured to physically attach and detach from said frame portion without requiring removal of said retention strap or said frame portion from said patient; a breathing limb coupled with said frame portion, said breathing limb providing air to said patient; and wherein said breathing limb delivers said air to said patient with said removable insert removed from said frame portion. ### Claim 15 (depends on 14) The mask of claim 14 wherein said removable insert enables access to a nose region of said patient without requiring removal of said frame portion. ### Claim 16 (depends on 14) The mask of claim 14 wherein said removable insert enables access to a mouth region of said patient without requiring removal of said frame portion. ### Claim 17 (depends on 14) The mask of claim 14 wherein said removable insert enables access to a nose region of said patient without requiring removal of said semi-rigid retention strap. ### Claim 18 (depends on 14) The mask of claim 14 wherein said removable insert enables access to a mouth region of said patient without requiring removal of said semi-rigid retention strap. ### Claim 19 (depends on 14) The mask of claim 14 wherein said removable insert includes a self sealing port. ### Claim 20 (depends on 14) The mask of claim 14 wherein said removable insert includes a therapeutic device accessible to said patient. ### Claim 21 (depends on 14) The mask of claim 14 wherein said removable insert is configured to provide a therapeutic function to said patient. ### Claim 22 (depends on 14) The mask of claim 14 wherein said removable insert is a different color than said frame portion. ### Claim 23 (depends on 14) The mask of claim 14 wherein said removable insert comprises an anti-fogging coating. ### Claim 24 (depends on 14) The mask of claim 14 wherein said removable insert is scented. ### Claim 25 (depends on 14) The mask of claim 14 wherein said removable insert comprises a graphic.
