Claim 0:
1. A method comprising:
receiving, by processing circuitry and from an oxygen sensor, an ambient air signal indicative of an oxygen partial pressure of ambient air;
receiving, by the processing circuitry and from an atmospheric pressure sensor, an atmospheric pressure sensor signal indicative of atmospheric pressure;
determining, by the processing circuitry and based on the atmospheric pressure sensor signal, the oxygen partial pressure of the ambient air;
determining, by the processing circuitry and based at least in part on the oxygen partial pressure of the ambient air and the ambient air signal, one or more calibration parameters;
calibrating, by the processing circuitry and based on the one or more calibration parameters, the oxygen sensor;
receiving, by the processing circuitry and from the oxygen sensor, a signal indicative of an oxygen partial pressure of a fluid; and
determining, by the processing circuitry and based on the signal indicative of the oxygen partial pressure of the fluid and the one or more calibration parameters, a calibrated oxygen partial pressure of the fluid.
