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-.


The determination of "blood gases" in the current clinical vernacular means the measurement of pH, partial pressure of carbon dioxide (PCO2), and partial pressure of oxygen (PO2) in fresh samples o...


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 ...


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.


McCanny, Venous vs arterial blood gases in the assessment of patients presenting with an exacerbation of chronic obstructive pulmonary disease. Ma OJ, Rush MD, Godfrey MM, Gaddis G. Arterial blood gas results rarely influence emergency physician management of patients with suspected diabetic ketoacidosis. Acad Emerg Med. 2003 Aug;10(8):836-41.


Central venous blood gases have been preferred because their correlation with arterial blood gases is the most well-established by research and clinical experience. Peripheral venous blood gases have been studied in critically ill patients as an alternative for patients who do not have central venous access.


OBJECTIVE: To investigate whether venous blood gases (VBG) test can be replace by an arterial blood gases (ABG) in exacerbation of chronic obstructive pulmonary disease (COPD). METHODS: From October 2005 to March 2006, at the Emergency Room of Kashan Beheshti Hospital, the data of 107 patients with exacerbation of COPD were assessed.


Venous blood gases can be drawn via several different methods. The location and method of sampling should always be considered when interpreting the results. Assessment of Carbon Dioxide, Bicarbonate and pH . In the absence of an arterial line, a venous blood gas sample can be used to evaluate carbon dioxide, pH and bicarbonate.

I was in ER with acute bronchitis..They did only a venous Blood gas. Chext X ray revealed left sided Atelectaseisis and acute bronchitis. What I am concerned over is the venous blood gas showed extremely low (even for venous) level of PO2 24 !! range 90-100 The O2 SAT was 40 (range 95+, The PCo2 wa 43 on venous (range 45 +_) and s also low at ...
