Abstract
An oxygen mask may include a convex shell having an upper portion and a lower portion and defining a chamber, a rim at least partially around the chamber, a nasal access port in the upper portion, and an oral access port in the lower portion. The nasal access port that is penetratable and/or puncturable to provide access to the chamber, and the oral access port may include a bite block defining a lumen and a valve in the lumen. The oxygen mask may include an inlet into the chamber, an outlet from the chamber, and a sampling port in communication with the chamber. The oxygen mask may include at least one fold or crease configured to allow the bite block to tilt relative to the horizontal axis and/or to translate along the vertical axis.

A mask comprising:
- a convex shell having an upper portion and a lower portion and defining a chamber;
- a rim at least partially around the chamber;
- a nasal access port in the upper portion that is penetratable and/or puncturable to provide access to the chamber;
- an oral access port in the lower portion, the oral access port having a front opening, a rear opening and a lumen therebetween, and including a bite block defining the lumen, and further comprising a duckbill valve disposed in the lumen, and
- at least one fold or crease extending circumferentially around a longitudinal axis of the bite block and configured to allow the bite block to tilt relative to a horizontal axis and to translate along a vertical axis
- wherein the fold or crease is configured to maintain the tilt relative to the horizontal axis and the translation along the vertical axis upon adjustment.
