Hello, this is an assignment that's due soon and I want to be
sure. How to calculate haemoglobin oxygen saturation given the %T
transmission values? (instructions provided). Are the answers I
have calculated correct? (They are highlighted around in yellow in
the table below). The %T values are recorded in the last column of
the table as well.

Calculating haemoglobin oxygen saturation An example of how to calculate % saturation Suppose that the %T values at 606 nm for fully oxygenated (100% saturated) haemoglobin and fully deoxygenated haemoglobin (+ Na dithionite) are 53% and 3%, respectively. %T (100% saturated) = 53% %T (0% saturated) = 3% If the %T reading at the applied pressure is 28%T then the %saturation value = (28-3)/(53-3) x 100 = 50% To calculate % saturation using your results use the following equation: (X - Y)/(Z-Y) x 100 Where X = the %T value at any oxygen partial pressure, Y = the minimum value of %T, Z = the maximum value of %T..
