WebJan 16, 2024 · Unfortunately, most VBGs aren't obtained with a simultaneous pulse oximetry. It would be nice to have a way to convert a VBG directly into an ABG, without having to know the arterial oxygen saturation. This can be done with the use of a third assumption. The difference in oxygen saturation is the difference between the venous and arterial ... WebMar 8, 2024 · VBG pCO2 is 4 lower than ABG pCO2. VBG pO2 is approximately 40 lower than ABG pO2. The bottom line is that for most of our clinical concerns, we can use VBG to assess pH and pCO2, and O2 sat to assess oxygenation. VBG may be less reliable in shocky or hypercapneic patients (but end-tidal CO2 will be useful in hypercapneic patients).

WebBlood gases are helpful to assess the effectiveness of ventilation, circulation and perfusion. Blood gases can be performed from cord, arterial, venous or capillary specimens. Repeated arterial stabs are strongly discouraged, as they are painful and do not represent oxygenation as well as pulse oximetry.
