You want to measure the blood oxygen level in a drop of blood using a pulse oximetry device. If you have a light source at 700nm, and 1mm of path length. What must be the concentration of, a.Oxidized hemoglobin (HbO2) concentration in blood so that the light intensity at the output decreases to the one tenth of input intensity?  b. Reduced hemoglobin (Hb) concentration in blood so that the light intensity at the output decreases to the one tenth of input intensity? c.At the concentration you found in b, what is Ii / If for oxidized hemoglobin?
