Accuracy and reliability of pulse oximetry at different arterial carbon dioxide pressure levels.


The present study aimed to assess whether arterial carbon dioxide pressure (Pa,CO(2)) has an impact on agreement between oxygen saturation measured with pulse oximetry (Sp,O(2)) or arterial blood gas co-oximetry (Sa,O(2)). Sa,O(2) and Sp,O(2) determinations were obtained simultaneously from 846 patients under assessment for long-term home oxygen therapy in… (More)
