Abstract
A nasal ventilation interface and method for providing nasal ventilation to a patient includes a hybrid face mask, covering only the mouth, coupled with removable nasal inserts extending from the upper surface of the mask. The nasal interface has modular, removable, and disposable nasal pillows connecting the upper surface of the mouth-portion of the mask to the user's nares. Each part of the hybrid mask is modular and can be formed in various shapes and sizes. The ventilation interface has differing gas line entry ports and can be shallow with a relatively deep soft facial interface or deep with a relatively shallow facial interface. In either case, the upper surface receives the nasal interface. The upper surface can have a removable ceiling in which is defined a nasal interface connector. The nasal interface can be integral with a removable ceiling. The entire hybrid mask can be made in one piece.
