It's confusing to me too because if the blood is 99% saturated with oxygen is there only 1% CO2? Is hyperventilating getting to 100% or further? Are we talking

Are we talking about the same numbers as a (calibrated) O2 optical saturation monitor reports or something else?

This is normally measured using an optical sensor. Blood O2 and CO2 percentages don't sum to 100%. O2 saturation refers to the percentage of hemoglobin molecules which have oxygen bound. Only some CO2 is transported bound to hemoglobin.
