Dr. Strong, I am delighted to have discovered your videos. I am a nursing student in Georgia and believe your instruction will be extremely helpful to me as I go through this process. The internet is a gift and I thank you for your time and thoughtful presentations. Michelle
I'm in a respiratory therapy program first semester and this video is GOLD! I love the directly proportional vs indirectly proportional analysis between pH and PaC02 to determine whether the patient is metabolically deranged or respiratory deranged. Thanks Doc!
MegaBuster00, I'm glad you have been finding these lectures useful. Regarding your question, there are 2 respiratory disorder examples in this particular lecture, one with a pCO2 of 60, and the other with a pCO2 of 85. If you are referring to something I said in a different lecture, in the event that I did say a PCO2 of 35 or 45 indicated a respiratory disorder is present, than it was just a misspeak and you are correct. (though keep in mind, the 35 and 45 cutoffs are a little arbitrary).
Sweetasfructose, that's a good catch (and a little embarrassing on my part). While the HCO3 was supposed to be more or less ignored in this lecture, given that the title is "simple acid-base disorders", I probably should have avoided using a mixed disorder as an example, even if I didn't expect viewers to recognize it.
Good lecture. Thanks. The only problem that I can see (and it would not happen very often), is if respiratory compensation has not occurred. The only way to diagnose a metabolic acidosis/alkalosis using the CO2 is if respiratory compensation has occurred. If respiratory compensation has not occurred, then we still would have to look at bicarb. Thank so much.
Very helpful video, thanks! Just have one question regarding example #3 - considering just the pH and pCO2 I understand that this is a respiratory acidosis but the HCO3 is decreased (although slightly) so wouldn't this factor make it to be a mixed disorder??
idk if this is correct because when i go off of my intuition, i get them right but when i use your method, i get them wrong. you cannot tell what an abg is just based off the ph and paco2... it just doesnt work that way
I'm not sure what you mean when you say you "get them wrong". Which acid-base problems are you referring to? Ones in the video, or ones in real life? If trying to apply this system to real life patients, keep in mind that you are on lesson 3. There are 20 lessons in the course. The next lesson covers mixed disorders - the identification of which involves determining if intrinsic mechanisms to compensate for acid-base derangements are successfully working, which has a lot of importance, particularly in complex, critically ill patients.
@@StrongMed thank you for the reply. yea i am applying these to real abgs in the acute care setting, education wise not for any clinical interventions. i will continue to watch all of the lessons first, but just as a first impression i was confused. but hopefully once i watch all 20 i will have a better grasp. thanks!
That makes sense. If you are only trying to classify the acid-base disorder from the ABG (i.e. not worried about the oxygenation, or about the differential diagnosis for the acid-base derangement), then only the first 7 videos and video #14 are relevant.
As a student these videos are great learning material. However you should consider acquiring another microphone or filter out the distracting white noise before posting.
I appreciate the feedback. I didn't think the white noise on the ABG videos is too bad (particularly compared to my earliest videos), but since this was recorded, I've actually changed both the microphone and software. Hopefully you'll find the audio in the newer videos better. I've considered going back and rerecording the older ones, as well as reformatting for widescreen and in HD, but it's so time consuming that it seemed to be a better use of time to cover more topics first.
Eric's Medical Lectures I appreciate your effort so much, thank you! I'd much rather have new topics than you, wasting your time on re-recording old videos, but maybe there's a software solution. You could look into that - put that hospital IT-department to work :P
This has to be the best channel on youtube
This is the best and most comprehensive discussion of ABG interpretation. Thank you, Dr Strong! 💪

Thank you Dr Strong. This series is one of the best , anyhow I forgot nearly all :(. This is a good lecture.
ABG interpretation made easy. Thank You Dr Eric.
Thank you so much for these videos. I have a difficult time with ABG interpretation. I am an ACNP student and this will help me so much.
thank you Dr Eric i am in psychiatry forgotten my medicine use all your videos for step 3 this is so good i am understanding acid base
Thank you so much sir for making the medicine so palpable so elegant ❤️
Great work sir,very helpful for PG students.doing MD medicine in india. this lecture series is very easy to understand

@7:00 it's metabolic acidosis alright, but not due to pCO2 though. Rather it's cuz of HCO3.
Dr. Strong, you're bloody amazing, I gave you a big and enthusiastic thumbs up! =3

O my, you made this so easy for me to understand. Thank you
thank you very much doctor , very informative and well done teaching
Thank you Doctor Strong
