Claim 19:
20. A device comprising:
a memory configured to store one or more calibration parameters; and
processing circuitry communicatively coupled to the memory, the processing circuitry being configured to:
receive, from an oxygen sensor, an ambient air signal indicative of an oxygen partial pressure of ambient air;
receive, from an atmospheric pressure sensor, an atmospheric pressure sensor signal indicative of atmospheric pressure;
determine, based on the atmospheric pressure sensor signal, the oxygen partial pressure of the ambient air;
determine, based at least in part on the oxygen partial pressure of the ambient air and the ambient air signal, the one or more calibration parameters;
calibrate, based on the one or more calibration parameters, the oxygen sensor;
receive, from the oxygen sensor, a signal indicative of an oxygen partial pressure of urine; and
determine, based on the signal indicative of the oxygen partial pressure of the urine and the one or more calibration parameters, a calibrated oxygen partial pressure of the urine.
