A Novel Calibration-Free Method of Measurement of Oxygen Saturation in Arterial Blood

In present-day pulse oximeters, oxygen saturation in arterial blood (SpO 2 ) is computed by utilizing an empirical relationship extracted from a calibration curve. The calibration curve is obtained by curve-fitting data acquired from volunteers. A novel method of computation of SpO 2 that does not r...
