The present invention provides a breathing apparatus and a controller for a breathing apparatus. The controller is configured to receive a first output signal from a pressure sensor in the breathing apparatus, wherein the first output signal is indicative of variations in a total gas pressure within the breathing apparatus. The controller is further configured to determine, using the first output signal, an oxygen consumption rate of a user of the breathing apparatus. This may enable the controller to determine the user's oxygen consumption rate, without having to rely on an oxygen sensor. The breathing apparatus may be a rebreather, which is used for underwater diving.
