A VBG (venous blood gas) is obtained from venous blood rather than arterial blood. While it is less painful for patients, its results have limitations compared to an ABG (arterial blood gas). [1] A VBG can detect CO2 retention but not assess oxygenation status. [2]

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.

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.

Test Name: VENOUS BLOOD GAS (VBG) General Information Lab Order Codes: VBG Synonyms: Venous blood gas CPT Codes: 82803 - Gases, blood, any combination of pH, pCO2, pO2, CO2, HCO3 (including calculated O2 saturation) Test Includes: VpH (no units), VpCO2 and VpO2 measured in mmHg, VsO2 and VO2AD measured in …

Jan 16, 2017 · 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 oxygen saturation (shown below).

Mar 4, 2019 · 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. This review will break down blood gas results into individual components to compare venous versus arterial results and evaluate whether these are clinically important differences.

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 less painful for the patient to obtain a venous sample compared to an arterial sample.

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.
