VBG or ABG? Which one to order?

the clinical value of VBG (venous blood gas) is discussed in this video, when can it be used as an alternative to ABG (arterial blood gas), how to interpret it and adjust for ABG, when not to use it, will provide you with some real-life clinical scenarios to make sure you understand this topic

Correction: Arterial PCO2 = PvCO2 - 8 (in the video I mentioned it's + 8)

Medical Lab tech here. Great video. albeit for a beginner it is full of depth. :)

I'm a new grad nurse, thank you so much for this video, very useful in helping me understand ABG and VBGs!

[@Hospitalista]

Happy you found it useful! Make sure to check other videos on the channel, I am sure you will find plenty of useful videos!

Thank you, so useful.
I hope you will correct this video as soon as possible.

[@Hospitalista]

Thank you, I thought I added a subtitle to correct the mistake! I’ll add a pinned comment with the correction. Thank you.

Thank you for the fantastic video - Why are VBGs not good in patients who are hypotensive? - Is it because the venous blood has more contact with the tissues of the body and thus has an increased amount of CO2 dissolved in it when compared to arterial blood? And if so, is this difference significant enough to contraindicate its use?

[@Hospitalista]

Thanks for reaching out and sorry for the late response! there is a debate how reliable VBG as an alternative to ABG in those unstable patients, given that uncertainty it's better to use ABG to make your clinical decisions in such unstable patients.

[@thesudaneseprince9675]

@@Hospitalista No worries and thank you for the reply

If an individual is a smoker, how long after the last cigarette would the oximeter reading be closer to accurate? Thanks

[@Hospitalista]

I really don’t know, never thought about this before.

[@eyobberihunali568]

Nice presentation and one comment. Arterial PCO2 = venous PCO2-5 and not +5

[@khawar9345]

surprized that Hospitalista did not correct the mistake Arterial PCO2 = venous PCO2-5 and not +5

[@Hospitalista]

Let me check, I thought I had added a subtitle in the video itself correcting that mistake!

[@professorsadikraja1662]

Really Good Video...

[@Hospitalista]

Thank you

[@areufkingkiddingme]

if sp02 is 99% any reason to ever get an abg over vbg

[@Hospitalista]

There’s no reason to get either with that Spo2. But ABG is the test to go for to assess for oxygen in the blood not VBG. VBG not reliable for that.

Give englis subtitles
