"WebSubgroup analysis showed that the accuracy of SpO2 appeared to be influenced by the type of oximeter, the presence of hypoxemia and the requirement for vasoactive drugs. Finally, high SpO2 thresholds were necessary to detect significant hypoxemia with good sensitivity. Conclusion: A SpO2 above 94% appears necessary to ensure a SaO2 of 90%. " - High spo2 low pao2

WebThere are a few reasons why the SpO2 can differ from the PaO2. Pulse oxygen can be less accurate for a few reasons such as hypothermia, poor perfusion states, and darker pigmented individuals. The software algorithms for SpO2 can also be less accurate with low SpO2 since you would have to place people in hypoxemic conditions to get reliable data.
