15. A Non-rebreathing Face-
mask with a reservoir bag
attached and three one way
valves (two on the front of
the mask, and a third
between the reservoir bag
and the mask) that allows
the patient to exhale CO2
out of the two holes on the
mask, but not be able to
breathe in air from the room
through those ports.
By not allowing patient to
breathe in air from the room,
which would dilute oxygen
concentration , this enables
the mask deliver close to
100% oxygen, as long as
oxygen flow is high enough
(10–15 L/min of).
