WebJul 13, 2012 · A priori, 15 physicians blinded to the study hypothesis set a consensus single threshold of <0.05 pH units and a variance in BE <2 as the greatest accepted difference between an ABG and VBG. The authors acknowledge that these thresholds are purely clinical and are not based on validated outcome measures. WebMay 19, 2024 · Serial ABG or VBG values will vary randomly by as much as ~0.03 differences in pH and ~5 mm differences in pCO2. (19091262, 8020270, 6407807, 1583545) So if the pCO2 increases slightly, that doesn't necessarily indicate that the patient is worsening – it may simply be noise due to repeated laboratory measurements.
