Capillary oxygen saturation
WebCapillary SO2 and tissue oxygen pressure (PtO2) were measured simultaneously in the cortex of n = 13 Wistar rats under normocapnic (PaCO2 = 36 mmHg) arterial normoxia (PaO2 = 92 mmHg), moderate (paO2 = 53 mmHg) and severe hypoxic hypoxia (PaO2 = 31 mmHg) with microreflectometry and multiwire surface electrodes. WebReference values of capillary blood saturation in neonates and its difference from pulse oximetry There is a statistically highly significant difference between the values of ScO2 and SpO2. Having the knowledge of this difference can increase the accuracy of clinical evaluation and further diagnostics.
