A system and method for automatically blending gases, comprising an input device for receiving predetermined mixed gas concentration data from the user, a plurality of gas inlet valves which allow a plurality of gas flows to enter a homogenizing chamber for mixing the plurality of gas flows into a mixed gas, at least one gas sensor for detecting the concentration of one or more components of the mixed gas and generating at least one output signal representative thereof; and a manager for receiving the at least one output signal and comparing the at least one output signal with the predetermined mixed gas concentration data and in response generating a signal to at least one gas inlet valve to modify the plurality of gas flows to maintain the desired mixed gas concentration. The system and method may further be used for the production of breathing gases for divers, such as Nitrox or Trimix, which significantly extend bottom time and reduce required decompression.
