Abstract

A respiration assist mask having an input gas feed tube, a ventilation interface, a facial interface and nasal inserts. The gas feed tube can connect to the ventilation interface and form a seal. The ventilation interface may be joined with the facial interface to form a seal between the ventilation interface and the facial interface, as well as between the facial interface and the face of a user. Additionally, nasal inserts may be inserted into a portion of the facial interface and form a seal between the inserts and the facial interface.
