ABSTRACT:
Apparatus for mixing two gasses, at least one of which contains oxygen, to a desired concentration of oxygen, comprising a mixing plenum, an inlet valve, for admitting one of the two gasses into the mixing plenum, an oxygen sensor for detecting oxygen concentration of mixed gasses in the mixing plenum and in response generating an output signal representative thereof, and a controller for receiving the output signal and a user input representing the desired concentration of oxygen, comparing the oxygen concentration of the mixed gasses represented by the output signal to the desired concentration of oxygen, and in response controlling the inlet valve to regulate flow of respective ones of the two gasses into the mixing plenum and thereby maintain the desired concentration of oxygen.
