<P> Pulse oximetry is a noninvasive method for monitoring a person 's oxygen saturation ( SO ) . Though its reading of SpO ( peripheral oxygen saturation ) is not always identical to the more desirable reading of SaO ( arterial oxygen saturation ) from arterial blood gas analysis , the two are correlated well enough that the safe , convenient , noninvasive , inexpensive pulse oximetry method is valuable for measuring oxygen saturation in clinical use . </P>
