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. WebSpO2 correlated well with arterial pO2 as predicted by the standard oxygen-hemoglobin dissociation curve in a undifferentiated critically ill patient population. In this study, a SpO2 >90% correlated with an arterial pO2 >60 mmHg more than 94% of the time.

Oxygen Saturation (02 Sat): Normal Ranges and How to Raise It

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%. WebIf a PaO2 level is lower than 80 mmHg, it means that a person is not getting enough oxygen . A low PaO2 level can point to an underlying health condition, such as: emphysema. chronic obstructive pulmonary disease, or COPD. How do you calculate PaO2 from SpO2?

WebMay 13, 2024 · The PaO2 and peripheral oxygen saturation (SpO2) are closely related and both are used to monitor oxygenation status. However, SpO2 values cannot be used as an exact substitute for PaO2. The aim of this study in acutely ill and stable patients was to determine at which SpO2 level PaO2 is more or less certain to be in the physiological range.
