Basic ABG Interpretation | Arterial Blood Gases (Part 3)

In this third lesson we start to begin discussing how we do the actual arterial blood gas interpretation and analysis. We hope this video lesson will help you in understanding blood gases and the process we go through to be able to interpret them.
We start with an introduction to serve as a primer of knowledge that you will use when doing the blood gas interpretation. We explain the basics of how these different values are adjusted by the body as well as the impact that they have on our patients and their arterial blood gas results.
From there we talk about the 4 main types of disturbances that you will encounter. Respiratory acidosis, respiratory alkalosis, metabolic acidosis, and metabolic alkalosis.
From there, we go on to talk about the 4 steps that you go through when starting any blood gas interpretation. We then move on to a series of examples in which we walk you through using these 4 steps in these basic abg interpretations.

As a Physiotherapy student currently doing respiratory module, thanks so much for these vids. They've been a great help

[@ICUAdvantage]

Glad you liked em!

[@Melissa-pw9fk]

Thank you so much! The ROME technique is so good. I honestly never been quite understanding the ABG value but now I can definitely interpret it!

[@ICUAdvantage]

YES!!! This is so great to hear!

[@moila04]

Love your videos, keep up the great work🙏. I find your videos so easy to understand. I find it difficult to understand people’s explanation at work but the way you explain it, i can learn fast.

[@ICUAdvantage]

Thank you thank you thank you! I really appreciate the awesome comment and again, really glad that you like the videos!

[@DivyaYadav-hf8uo]

Thank you for explain in very basic manner and step by step , with help of this I could learn ABG reading very well... Keep uploading and teaching..

[@sadhanajangir4906]

Hey! Eddie Thank you so much for videos Whenever I stuck in ICU things your videos are the first to come in my mind So thank you ❤👍

[@jeroenvangent6675]

Hello ICU advantage! I love your videos to refresh my knowledge. Im a ICU nurse scholar in the Netherlands. I was wondering, I learned that CO2 is not an acid but an indirectly measurement of H+. Therefore to make it easy, CO2 is called an "acid". What are your thoughts? 😁

[@belindahjepkemoi3482]

Have learnt alot ,thank you

[@ICUAdvantage]

Awesome! You're welcome!

[@jessyjohny5703]

extremly helpful vedio sir.thank you sir.

[@ICUAdvantage]

Great to hear this. Your're welcome!

[@rosegoodwin1012]

Hello, what do the FHHb and and FO2Hb mean in these testing? And what would cause abnormalities? (E.g FHHb 47 and FO2Hb 51.5)

[@lucyberger7625]

great video. However I would love some explanation regarding when the ABG is compensated or partially compensated. Thats where I get confused.

[@ICUAdvantage]

Thank you. I actually cover that in other lessons in the series: Compensation: kzbin.info/www/bejne/gpnbmmd-Z9uXp7c Tic-Tac-Toe Method: kzbin.info/www/bejne/b6DMq5Rsgdl8edE

[@jehanyounan1372]

i wondering how increase of HCO3 absorption by the kidneys => make ph more alkaline? as i get rid of alkaline base i thought that will make ph more acidic i can't get this point if you can help

[@jildahotmstrom6673]

Thanks

[@ICUAdvantage]

Welcome

[@mr.spicyhotdog]

Hi there! Really love all your videos. Just wondering because I encountered this at work. I've done an ABG then showed it to the consultant. The doctor then ordered A bolus of 250ml hartmanns / Compound lactated solution. Wanted to know what triggered the doctor to order this? :)

[@ICUAdvantage]

What kind of unit do you work, or patients do you normally encounter? I've seen in the trauma and surgical word mostly the base excess being used to determine a patients fluid status with the presumption of hypoperfusion driving the deficit. Also why we avoid NS, in which the hyperchloridemia can alter the BE and lead to improper clinical decision making. Thanks for the comment and glad you like the videos!

[@mr.spicyhotdog]

@@ICUAdvantage I work in ICU. All I can remember is that the ABG was acidic with a little high on CO2, around 7.2 I think. Couldn't remember the BE and bicarb though 🤔

[@missjackson9680]

Thank you so much for this!! This is the first time I’ve actually understood this!! Throughout 4 years of college, 5 years at bedside I have never understood this. I just started in ICU and I’m so glad I found your content.

[@32ahmmed]

Thx

[@ICUAdvantage]

You're welcome Ahmed!

[@melindast-pierre1896]

What could we expect of an ABG of an inconscient patient? Respiratory alk?

[@ICUAdvantage]

If they aren't breathing or breathing well we'd expect a respiratory acidosis as CO2 would be retained.

[@ayannageorge5258]

What if I have: pH - 7.38, pCO2 - 20; HCO3 - 12, sO2 - 99.6?

[@willmskarina]

Fully compensated metabolic acidosis?

[@ayannageorge5258]

@@willmskarina thanks. Was wondering.

[@robertdove6660]

How can CO2 be acidic itself? It does not have hydrogen. It does create an environment of unbound hydrogen. Wouldn't the Hydrogen being left over from the expiration of CO2 during respiration create an acidic environment instead? Left over Hydrogen? As well with HCO3, since it is bound to Hydrogen, it means that Hydrogen is tied up and subtracts from available Hydrogen levels there by decreasing pH making it more alkali? HCO3 shouldn't be Alkali itself, but because it holds the Hydrogen it subtracts from overall hydrogen levels? Man I am confused.

[@tortillero3138]

You answered your own question, increased CO2 would cause increased H2CO3, which would then cause increased HCO3- and H+
