Abstract:
1. A physiological parameter measurement method comprising: determining a physiological measurement including an indication of a relationship among light intensity values at three or more wavelengths, the light intensity values obtained in response to detection of light at the three or more wavelengths after transmission into a tissue site and attenuation by the tissue site; selecting at least one of a plurality of reference data sets corresponding to the physiological measurement, the reference data sets being empirically determined and each including a respective indication of a relationship among empirically determined light intensity values for a respective measurement at the three or more wavelengths; comparing the physiological measurement to the selected at least one of the reference data sets at the three or more wavelengths; and determining, based on the comparison, whether or not the physiological measurement represents a physiologically significant measurement.
