Jul 5, 2023 · This guide describes the venous blood gas (VBG) test, explains key differences from an arterial blood gas (ABG), and provides an approach to VBG result interpretation. Understanding how a VGB differs from an ABG is important.

Oct 17, 2022 · The venous blood gas panel is one of the most useful tools we have to help us understand why the pH is deranged, and gives us information we don’t get from other laboratory panels. Specifically we can get a huge amount of information from the pCO2, bicarb, and lactate.

Apr 27, 2023 · ABG/VBG is a useful tool to evaluate for hypercapnia. For example: In a patient with COPD and encephalopathy, ABG/VBG would be a rational tool to evaluate for the presence of hypercapnic encephalopathy.

Mar 12, 2025 · The blood gas is used to rapidly assess ventilatory function and identify acid-base disorders – and will also generally provide point-of-care testing of a number of values such as electrolytes, blood glucose and haemoglobin.

A venous blood gas (VBG) can estimate pH and CO 2 properly but cannot offer good O 2 data. As a result, ABG has become the gold standard in patients who are ill and at a risk of rapid decompensation, have a respiratory component, or are admitted in hospital settings.

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 that venous pH has sufficient agreement with arterial pH for it to be an acceptable alternative in clinical practice for most patients

In the intensive care unit, emergency department, and respiratory floors, many clinicians use venous blood gases (VBGs) instead of ABGs to estimate indices of ventilation and acid-base disturbance (ie, systemic carbon dioxide [CO 2] and pH).

Venous blood gas (VBG) interpretation . Arterial blood gases (ABGs) are commonly used for estimating the acid-base status, oxygenation and carbon dioxide concentration of unwell patients. However, arterial blood can be difficult to obtain due to weak pulses or patient movement.

Blood gas testing shows if you have the right amount of oxygen and carbon dioxide in your blood. It also shows whether your blood is too acid or too alkaline. This is called your acid-base balance or your pH level. In blood gas testing, samples of your blood are usually taken from an artery.
