Assessment of accuracy of two pulse oximeters in infants with cyanotic and acyanotic congenital heart diseases
Authors' conclusion
In lower range saturations between 70% and 85% the accuracy of both pulse oximeters exceeded the threshold of ≤3% recommended by the Food and Drug Administration (FDA).
Study context
- Population
- Infants with congenital heart diseases, arterial oxygen saturation 70–100%153 measurements
- Participants
- 44 infants
- Comparison
- Philips IntelliVue X3 vs Nellcor OxiMax pulse oximeters, each vs arterial saturation (SaO2) by co-oximetry
- Outcome
- Accuracy of SpO2 vs SaO2 (arterial blood gas analysis): median bias and accuracy root mean squared index (Arms), by SaO2 subgroup
