What is the valve on a mask?
One valve is between the face mask and a plastic reservoir bag (typically 1 liter) that’s attached to a supply of oxygen. The valve doesn’t allow exhaled air or outside air from entering the bag, so only oxygen flows from the bag to the mask. The other valve allows exhaled air to flow into the atmosphere but doesn’t allow the outside air to enter.
