Do commercially available pulse oximeters accurately measure oxygen saturation compared to arterial blood oxygen saturation in clinical conditions?
Five commercially available pulse oximeters demonstrate similar accuracy to arterial blood oxygen saturation in the 80-100% range, though they slightly underestimate true saturation.
Taylor et al. (1988) studied this question.
