The goal of this study was to evaluate the accuracy of pulse oximeters over the range of 70-100%. Two devices were placed on each subject with one on the finger and the other on the fingertip. SpO2 measurements from these devices were compared to sampling of arterial blood during brief stable oxygen desaturation in healthy volunteers to evaluate the claimed range.
