Determination of oxygen saturation in circulating blood from pulse wave amplitude

Conclusions 1. Within the range 0.75<S<1, the values of coefficient α are from 0.4 to 1.5 for wavelengths λ1=650, 660 nm and λ2=805, 940 nm. 2. Errors in calculation of δs within the range ofS from 0.75 to 1.0, as calcualted from α using simplified Eqs. (5) and (8), are more than 1% and 0.095%...
