Abstract :
Results are presented of an investigation of the effectiveness of using an EKG signal as a synchronization technique to improve pulse detection and overall accuracy of pulse oximetry. The unprocessed red and infrared transmitted signals representing the photoplethysmographic waveform were recorded from commercially available pulse oximeters. The arterial oxygen-saturation values output by these pulse oximeters were compared with recomputed results using EKG synchronization to determine possible improvements, particularly with controlled motion artifacts.<>
