Blood gas analysis is an important part of the evaluation of patients with severe respiratory and metabolic derangements. Arterial blood gas (ABG) analysis is the gold standard for assessing acid-base and ventilation status but can be technically difficult, increase patient discomfort, require an additional needle stick, and may result in complications 1 with rates up to 11.3%. 2 Venous blood ...

Arterial blood is mainly used to measure the acidity (pH), oxygen concentration, and carbon dioxide concentration in the blood. The test method is called the arterial blood gas (ABG) test. It is used to check the efficiency of the lungs to remove carbon dioxide from the blood as well as to take oxygen into the blood.

PURPOSE: To determine whether the use of venous blood gases can be a suitable alternative to arterial sampling to evaluate acid-base status. METHODS: The database of the clinical laboratory in a large academic hospital was searched for records of venous blood gas analysis and an arterial sample taken within ten minutes from the same patient.

Background: Arterial blood gases (ABGs) are the gold standard to assess acid-base balance, ventilation and blood oxygenation. However, using venous blood gases (VBGs) could avoid the pain and complications associated to ABGs. No studies have assessed if VBGs are comparable to ABGs in reaching the same diagnosis of normal vs. abnormal pH, CO2, and HCO3-.

At the present time, arterial blood gas analysis is the gold standard for assessing the acid–base status, though there are reports on the agreement of base excess and lactate levels determined in arterial and venous blood. 39,40 However, the popularity of venous blood gas analysis is low and some studies have expressed reservations regarding ...

Background and objectives: Venous blood gas (VBG) analysis is a safer procedure than arterial blood gas (ABG) analysis and may be an alternative for determining acid-base status. The objective of this study was to examine the agreement between ABG and central VBG samples for all commonly used parameters in a medical intensive care unit (ICU) population.

Thus, this strategy is unable to yield a universally applicable equation which can relate arterial and venous blood gas values. Similar variation is notable when evaluating the published literature regarding ABG vs. VBG comparison, explaining why these equations haven't gained clinical acceptance.

Venous to arterial conversion (v-TAC) is a software (Obimedical, Denmark), which can convert venous blood gas values to arterial blood gas values. The principle of the method is a mathematical transformation of VBG values to arterialized values (aVBG) by simulating the transport of blood back through the tissue.
