In the standard benchtop oximeter, it can be shown that the Saturated Oxygen levels in a sample of blood can be related to the absorbance at two wavelengths, Alxan) and At(12), by the following relationship Sao, = X – Ý » Ang Where X and Y are two coefficients that are functions of the molar absorptivity, e, of the reduced and Oxy forms of haemoglobin. The oximeter is calibrated by a two-point calibration using standard samples of 0% Oxygen concentration and 100 % Oxygen concentration. For the 0% Oxygen sample, the values of measured absorbances are Af(1) = 0.3 and A (12) =0.5; For the 100% Oxygen sample, the values of measured absorbances are Alyan) = 0.38 and A(A2) =0.9. Calculate the values of the coefficients X and Y in the relationship given above

thus X = 337.496 and
Y = 562.493

given relation! At (de) Sa Uz = X-Y . (At(da) for salg: 0 % Ata 0.3 = 0.5 thus, 0 = x-Y13) X = Y(3/5 0 for sal₂ = 100 % Atti)
