Traditional oxygen delivery with a mask or cannula washes out end-tidal CO2 readings making them almost unusable. This becomes even more problematic when higher flows are needed. A typical CO2 reading looks something like this:
CO2 reading accuracy significantly improves when using the Sovant because it turns off oxygen during exhalation when it is not needed allowing for an accurate CO2 sample. Accurate end-tidal CO2 when using the Sovant provides much greater insight into the effect of sedation on patient ventilation.
