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%. WebNormal values for PaO2 are 10.5–13.5 kPa, and for SaO2 are 94–98%. Obtained via arterial blood gas (providing PaO2and SaO2) and pulse oximetry (providing peripheral capillary oxygen saturation; SpO2). Normal values decline with age and are influenced by the presence of comorbidities such as chronic lung disease [1].
