Abstract
A breathing apparatus for an aircraft crew member has a breathing mask provided with a demand regulator and connected to a source of breathing gas, such as a pressurized oxygen cylinder or preferably an OBOGS. The apparatus includes an individual buffer plenum specific to the mask on a line for feeding the regulator of the mask from the source. The volume of the plenum is sufficient to provide for at least two typical breaths of the mask wearer in succession. A non-return check valve is located between the plenum and the source.
