Reviewed and revised 7 January 2016 OVERVIEW Venous blood gases (VBG) are widely used in the emergency setting in preference to arterial blood gases (ABG) as a result of research published since 2001 The weight of data suggests that venous pH has sufficient agreement with arterial pH for it to be an acceptable alternative in clinical […]

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 between them.

The present study attempts to describe the agreement between arterial and venous blood values (pH, bicarbonate, partial pressures of carbon dioxide (P co 2) and oxygen (P o 2)) in order to determine whether VBG could replace ABG in the initial assessment of adult patients in an ED where diverse pathological conditions are encountered.

Venous versus arterial blood for gas analysis ... The notion that patient blood pressure affects A-V difference of blood gas parameters is explored by a recently published study from Iran. ... agreement between arterial and venous values is likely to be better among patients with normal blood pressure than among those who are hypotensive.

The sites from which venous blood can be sampled, measurements that can be performed on venous blood, and correlation of venous measurements with arterial measurements are reviewed here. Other alternatives to ABGs for estimating systemic carbon dioxide and pH are also described, including end-tidal carbon dioxide and transcutaneous carbon dioxide.

The major difference is that electrolytes are usually measured on venous blood and blood gases on arterial blood so there is a 1-2 mEq/L due to the arterial-venous difference. There is an additional potential difference of 1.5 mEq/L due to the inclusion of dissolved CO 2 and carbonic acid in measured c tCO 2 .

Doctors give unbiased, helpful information on indications, contra-indications, benefits, and complications: Dr. Karamanoukian on venous vs arterial co2: in the cord I forget which one has the oxygen, but that has the good air and not the bad air. I'm pretty sure it works reasonably with arterial going IN with oxygen and nutrients and coming back out with wastes and CO2.

Taking the difference between arterial and venous blood into account is important for health care providers. As described by WebMD, most blood samples are taken from a vein because veins generally have a larger interior volume and lower system pressure than arteries. Veins also tend to be closer to the skin and easier to access.

But, venous blood is rich in metabolic wastes such as carbon dioxide and urea. Since arterial blood is rich in oxygen, the color of the blood is bright red. The color of the deoxygenated venous blood is blackish red. The main difference between arterial and venous blood is the amounts of oxygen dissolved in each type of blood. Reference:

The difference between PCO 2 in mixed venous blood (PvCO 2) and PCO 2 in arterial blood (PaCO 2) is defined as the mixed venous-to-arterial CO 2 tension gap [Pulm (P-a) CO 2] and is affected by cardiac output and global CO 2 production, as well as the complex relationship between PCO 2 and CO 2 content .
