1. A method comprising:
providing an oximeter device;
using the oximeter device comprises making an oxygen saturation measurement of a tissue comprising emitting light from a source of the oximeter device into the tissue, and receiving light reflected from the tissue at detectors of the oximeter device in response to the emitted light, wherein a plurality of detector responses is obtained for the reflected light;
accessing data points for simulated reflectance curves stored in a memory of the oximeter device;
fitting the detector responses to the data points for the simulated reflectance curves to determine an absorption coefficient value for the tissue;
using the absorption coefficient value, determining an oxygen saturation value for the tissue;
calculating an error value from the fitting of the detector responses to the data points of the simulated reflectance curves, and using the error value, determining a quality metric value for the oxygen saturation value; and
displaying on a screen the oxygen saturation value and the quality metric value.
