Abstract

A face mask that may be used for bag-mask ventilation, during the induction of general anesthesia for example, and allows for two-handed or ambidextrous use. The face mask includes a dome connected to a deformable rim, which forms an enclosed air space when the rim is pressed against a patient's face. The dome has a connection port and a contoured outer surface adjacent the connection port. The contoured outer surface includes contour features such as a pair of crossed composite recesses which may each receive a different one of a user's thumbs. The connection port is aligned with the patient's mouth when the mask is in use and an adapter may be included that attaches to the connection port and provides a ventilation port as well as an intubation port that is aligned with the mouth.
