The venules and arterioles join together in capillary beds forming a mixture of venous and arterial blood. The specimen from a dermal puncture will therefore be a mixture of arterial and venous blood along with interstitial and intracellular fluids.

For arterial samples (0.5–1 ml), a minimally heparinised plastic syringe with 24 G needle was used to puncture the radial artery. For venous sampling, blood was obtained at the time of intravenous cannula placement or using peripheral venepuncture.

acutecaretesting.org/.../lactate-measurement-arterial-versus-venous-blood-sampling

Summary This article evaluates venous blood as an alternative to arterial blood for lactate measurement, highlighting the general considerations related to each of the three types of venous blood which can be used for lactate measurement: peripheral venous blood, central venous blood and mixed venous blood.

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.

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.

A venous blood gas (VBG) is an alternative method of estimating systemic carbon dioxide and pH that does not require arterial blood sampling. Performing a VBG rather than an ABG is particularly convenient in the intensive care unit, since many patients have a central venous catheter from which venous blood can be quickly and easily obtained.

Arterial vs Venous. Blood samples from DUI suspects are commonly withdrawn from the vein rather than from the artery. Yet the blood-alcohol content of venous blood can be quite different from the content of arterial blood in a subject at a given time – and it is the blood in the arteries that is carrying alcohol into the brain, resulting in intoxication.

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 […]

en.wikipedia.org/wiki/Venous_blood

Venous blood is typically colder than arterial blood, and has a lower oxygen content and pH. It also has lower concentrations of glucose and other nutrients, and has higher concentrations of urea and other waste products. The difference in the oxygen content of arterial blood and venous blood is known as the arteriovenous oxygen difference.

Capillary blood is not identical to venous blood. However, in many applications, these types of blood samples yield quality results for researchers and physicians alike. Capillary blood is a combination of arterial and venous blood. From the right side of the heart through the lungs, oxygenated arterial blood flows into the capillaries.
