Venous blood gases (VBG) are widely used in the emergency setting in preference to arterial blood gases (ABG) as a result of research published since 2001; The weight of data suggests …

Venous blood gas (VBG): Done to study the gases, such as oxygen and carbon dioxide, that are dissolved in the blood. Arterial blood gases (ABG): Measures how effectively the lungs move …

There is currently a plague of ‘venous’ blood gases (VBG) in clinical practice. A VBG is obtained by placing a venous sample in the arterial blood gas analyser. VBGs are popular as it is far …
