What Is the Normal Range of SaO2?

The normal range of SaO2 is around 97 percent, although anything in the region of 95 to 100 percent is considered to be within the norm. When combined with PaO2 and CaO2 readings, this range gives a good indication of a patient's blood oxygen levels, and whether they are adequate. As a result, while SaO2 levels are important, they are only one part of the wider picture.
