METHOD AND APPARATUS UTILIZING ELECTRICAL RESISTANCE RATIOS DERIVED FROM BLOODLESS AND BLOOD DATA FOR DETERMINING THE PERCENTAGE OXYGEN SATURATION IN BLOOD |
摘要 |
Spectral data is obtained with respect to both bloodless and blood specimens. Signals are derived from this data representative of certain ratios and these signals are processed so as to obtain a direct indication of the percentage oxygen saturation without resorting to logarithmic relationships.
