Arterial blood gases (ABGs) are commonly used for estimating the acid-base status, oxygenation and carbon dioxide concentration of unwell patients. As such, a venous blood gas (VBG) is an alternative method of estimating pH and other variables. …
What is the difference between ABG and VBG?
ABGs can be more difficult to obtain, are more painful and require arterial puncture that risks complications. A peripheral venous blood gas (VBG) can be obtained as the nurse obtains IV access upon patient arrival, requiring no additional sticks or risk of arterial injury.

What is the PCO2 in venous blood?
The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa.
