WebGreater resolution in the PPG measurements will reduce the uncertainty in the SpO 2 algorithm. With a typical PI of 1% to 2% for wrist-worn SpO 2 sensors, the goal of pulse oximeter design is to increase the PI through mechanical design or to increase the dynamic range. The spacing of the LED to PD will have a major effect on the PI. WebMost pulse oximeters are accurate to within 2% to 4% of the actual blood oxygen saturation level.
