A controller for controlling a breathing apparatus that comprises a plurality of oxygen sensors, each for sensing an oxygen content of a gas in the breathing apparatus, the controller being configured to control the operation of the breathing apparatus based on the output of one or more of the oxygen sensors and additional information relating to the operation of the breathing apparatus. Also a breathing apparatus comprising the controller and the plurality of oxygen sensors.

Controller for, and method of, controlling a breathing apparatus

A method and apparatus for automatically controlling partial pressure of oxygen in the breathing loop of a rebreather diving system. A diver may adjustably select a control parameter to maintain partial pressure of oxygen at a setpoint that varies with ambient pressure and is within a range between a maximum safe partial pressure of oxygen at depth and a minimum safe partial pressure of oxygen for the purpose of biasing the performance of the rebreather either towards minimizing gas venting from the rebreather breathing loop or minimizing decompression time. A method and apparatus for managing and monitoring the use of dive resources in comparison with a target dive time specified by the diver, calculating and indicating remaining dive time based on dive resource values and calculating and indicating dive resource values required to meet preselected dive resource end values and dive requirements.
