How to convert venous blood gas values to arterial values Arterial blood gas is the gold standard for blood gas and acid-based testing in critical care. There is a trend towards the use of venous blood, as venous punctures are less invasive for the patient and less complex for healthcare providers.. Clinical parameters differ between arterial and venous samples.

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.

Peripheral venous blood gas (PVBG) analysis is increasingly being used as a substitute for arterial blood sampling; however, comparability has not been clearly established. To determine if the pH, PCO2 and PO2 obtained from PVBG analysis is comparable with arterial blood gas (ABG) analysis. A search …

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-.

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.

Arterial vs Venous Blood . Although these terms may sound a little familiar, the particulars are not commonly known. Therefore, the importance of bringing up the particular properties of venous and arterial blood would make more sense in understanding those. This article will not only discuss the properties, but also emphasize the differences ...

Rationale: Blood gas analysis is often used to assess acid-base, ventilation, and oxygenation status in critically ill patients. Although arterial blood gas (ABG) analysis remains the gold standard, venous blood gas (VBG) analysis has been shown to correlate with ABG analysis and has been proposed as a safer less invasive alternative to ABG analysis.

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.

As a Respiratory Therapist, one of the skills you will be performing most is Arterial Blood Gas (ABG) sampling and analyses. The results of an ABG can serve as one of the most accurate ways to assess a patient’s clinical condition, and often times will be the deciding factor between whether a patient has to endure the trauma of intubation and mechanical ventilation, or, be managed less ...
