| Abstract: | A new optical measurement technique based on spectral scanning is described for the determination of oxygen saturation of whole blood. The principles of this technique are outlined, together with a calibration procedure used to test its feasibility in vitro. The preliminary results show that the accuracy of the new technique is of the order ± 2% over the full range of oxygen saturation. This degree of accuracy is comparable with commercial CO-oximeters. |
