Organizing and summarizing search results for youThe accuracy of a Venous Blood Gas (VBG) is generally considered to be less than that of an Arterial Blood Gas (ABG), particularly in measuring oxygen and carbon dioxide levels. However, recent evidence suggests that VBG and ABG results can be quite consistent, especially for pCO2 measurements. Additionally, venous pH has sufficient agreement with arterial pH, making VBG an acceptable alternative in many clinical situations. Overall, while VBG may not be as accurate as ABG, it is still a valuable tool in clinical practice.3 SourcesVenous Blood Gas (VBG) Interpretation - Geeky Medics
A VBG is a venous blood sample drawn into an ABG ( heparinised ) syringe and then run through a blood gas analyser.
