OximeterApneaNoninvasive monitoring of arterial oxygen saturation by means of pulse oximeters is currently a routine procedure in a wide variety of medical disciplines. Particularly, oximetry tests are a reasonable means of first-line testing for sleep apnea. An oximeter with recording capabilities, ...
Most researchers, when they measure the time difference between the peak of the R-wave in the electrocardiogram (ECG) signal (corresponding to left ventricular depolarisation) and a fiducial point in the photoplethysmogram (PPG) waveform (as measured by a pulse oximeter fingertip), describe this...
