Perhaps the easiest solution would be specially calibrated oximeters for people with darker skin - or a switch to change mode of the device. I would not call it racial bias - skin color is just one genetic trait like color of eyes and as should be accounted for but if everyone around you has green eyes, perhaps it is easier to not have an idea to account for variability. Therefore including non homogeneous set of test participants is crucial.
