The measured spectrum is compared to a model spectrum calculated from the
determined concentrations. The difference between these two spectra is called
the residual spectrum. If this residual spectrum is too high, the oximetry module

flagged with a warning.
In addition, a warning will accompany the results if any of the following
conditions exist:
 ctHb < 0.1 mmol/L or ctHb > 25 mmol/L
 FHb(deriv) < –2 % or FHb(deriv) > 102 %
