This is video is recording of the regular ICU classes taken by Dr. Ankur Gupta (Intensivist) in the hospital.
The session is titled "Master how to read and solve an ABG (arterial blood gas) in 60 minutes" and explains reading and solving an ABG (arterial blood gas).
The session explains in details:
0:00 Introduction
2:45 Oxygenation Status (including Alveolar-Arterial gradient and P/F ratio)
18:58 Ventilation Status
21:59 Acid Base Status
28:05 Metabolic Acidosis (High anion gap metabolic acidosis [HAGMA], normal anion gap metabolic acidosis [NAGMA], low anion gap metabolic acidosis, negative anion gap metabolic acidosis)
50:38 Metabolic alkalosis (chloride dependent/ fluid responsive , chloride resistant/fluid unresponsive)
52:36 Respiratory Acid base status (respiratory acidosis and alkalosis)
We hope that this session will make ABG very simple and easy for you now . Hope ABG interpretation will now be a fun and fascinating thing. Keep practicing and if you have any doubts in ABG solving, you can post and ask your queries on esbicm.org/forums

regularcrisis.com is dedicated to doctors and nurses who regularly manage crisis like situations in ICU & ER.
Intensive care unit and emergency department are the backbones of any hospital where all critical situations are managed. Everyday is a crisis like situation there and with time the team working there get used to it with. With time, their skill gets more sharpen with which they manage these situations more and more efficiently each time.
But most importantly, the experience which they accumulate is invaluable; their experiences teach them things which at times are not mentioned in the regular textbooks. What if this experience is shared with the doctors and nurses who are newly joined in ICU and ER!
Regularcrisis.com serves this purpose only. We share educational material (mainly videos and forums discussion) which is a blend of latest guidelines and rich experience of ICU and ER teams.
We hope that his small effort of ours will be of some help to those working in ICU and ER.
Update: regularcrisis.com is now affiliated with ESBICM* for creating educational videos for health care working in ICU and ER.

G8 ...u r doing very very good job....this should be way things must be taught in college
Thanks & regards
So nice of you
You are ultimate sir, I think you should start your own app recording these wonderful lectures
Already on it
True sir. Let us know once started
Excellent explanation sir 👍
Thanks
Well explained sir
Thanks Sir!🙏🌹❤
Thank you so much sir
Thank you very very much sir . I wish I could got it earlier.
Most detailed and practical ABG concepts explained in such a lucid manner here...
Thanks sir.
Thanks a lot , glad it helped
sir more i listen to u , my love toward you is getting more and more
So nice of you
Excellent lecture 👍👍
Many thanks, glad it was helpful
Very helpful....
Thank you sir
Highly informational video
@ 22.34 "that smile" is for those who directly jump on pH levels judgmental being acidosis/alkalosis before seeing pO2 and pCO2 levels in ABG.
very nice explanation
Thanks , glad u liked.
Good👍
Thanks a lot sir ❤many thanks
Best💯
Thanks u sir🙏
hi, excellent lectures
Glad you like them!
Sir pls make videos on cardiology in micus , valvular heart diseases, insults , etc. Thanking you
Sir you are the best teacher.Thanks will be less for your efforts.Sir please take classes on acid base disorders and electrolytes in details..
Thank u , your suggestions noted
when do you supplement HCO3 in HAGMA and how?
kindly guide me, thanks
Nice
Hello Sir, what is the role of Lactate and Base excess in interpretation of ABG ,
Thanking you in advance🙏🙏🙏
Sir plz make a video on how to give insulin acording to sliding scale or algorithm .
Sir , should the K+, Na+ , Cl-, given in the ABG Report can also be taken as true and surmise the effect of Acidemia/Alkalemia . Or a separate Serum electrolyte Test should be done instantly. Are the amount of the NA, K, Cl dependable as given in the ABG Report? Kindly answer. its a necessity.
*You tried to cover extremely vast topic in short time good efforts. PO2, which is dissolved oxygen in blood, is responsible for HB saturation(Spo2) & not the other way round. Again Hypoxemia is relavant, we should analyse low PO2 clinically, E.g in Acute Exa of COPD there is acute rise in PC02, & P02 may be Less than 50 in v/o low PA02 & Spo2 which may be less than 60, but is easily correctable with a litre of Oxygen. If we consider this severe hypoxemia & give high concentration of Oxygen patient will go into CO2 narcosis (coma) within minutes, whereas P02 of 60 in patient with Acute Pancreatitis may be detrimental & may herald ventilatory support. Whether it's Hypoventilation, V/Q mismach or shunt which matters more.*
*Secondly when PH is low doesn't mean low HC03 but possible high HCO3 (compensatory) & High PCO2. Regarding AG we should simplify it, just calculated AG by formula & correct it, when Albumin is Low, add 2.5 X Albumin (4.5 - present alb) that would be corrected AG & now see the Delta HC03 & Delta AG,they should be equal in simple acid base disorder (Normally change in bicarbonate should be equals to change in AG), if not then mixed disorder likely.OR calculate Delta ratio which is more correct. Uremia/ Renal failure is one of the major cause of HAGMA in ICU. Regarding compensation in Acute & Chronic Respiratory acidosis it's usually 1 & 4 rise in Bicarbonate respectively & In Acute & chronic Respiratory alkalosis it's 2 & 5 decrease in Bicarbonate respectively. It's easy to use Winters formula while calculating expected PCO2 in Metabolic acidosis.Unless patient is gasping, obtain ABG @ room air...keep it up.👍🏼*
Well said nitin.
But didn’t get what you meant by dissolved o2 and bound by Hb… we have said that only in the video above. Anything different?
Sir i m paediatrician and i learnt more frm u dn my picu posting in pg
D advantqge is dat i m working in tribal area but i manage pt here only bczz of u
such a nice compliment dear... we are planning to start the live classes also on youtube live which everyone can join... very nice to hear that our videos are of some help.
@@TheICUChannel waiting for classes 👏
Thanku for elaborating ABG.
thanks and welcome to ESBICM
@The ICU Channel by ESBICM, SIR have not understood the concept of corrected HCO3, having M.Alkalosis when the Main Disorder is acidotic and PH < 7.35, kindly elaborate more
can you post on the telegram group where I can voice message as this is difficult to type in detail .
Abg values in aspiration pneumonia
Sir please share a video to how to a central line incertain
Ok we will try , but many videos already available on this on net . What exactly the problem you are facing ?
sir it will be better for us if you give units of various variables while explaining.
👏👏
What is normal alveolar arterial gradient sir . ?
Is corrected and expected anion gap the same?
I was watching your weaning from vent
How do checks cough while on vent
Sir why minus 2 and plus 4 in pH correction?
Sir what is the significance of expected AG in treating the patient
Sir, urine Ph more than 6.5 or 5.5 in type-1 RTA.
👏👏👏🙏🏼🙏🏼🙏🏼🙏🏼
I think you add up to actual anion gap with each 1gm/dl fall from 4. You said subtract
Yes it should subtract … can you point out the video time where the confusion arised?
Sir ,as this channel has grown tremendously from past 3 years ,hence is it possible to take this same class again . ?
Noted , will do a livestream
sir kaafi kch clear hua abg ko lekr is video mai...thnq sir...par sir agr thoda simpal language m use kre to better hoga..ku ki muje icu join kiye kch months hi huye h🙏🙏🙏🙏🙏🙏
we are planning for an updated version , but it will take time ... but we will make it in parts. keep practicing it will become simple.
How to measure urine anion gap in NAGMA .
Sir 1 have a question.....🙋♀️
pH 7.20, pco2 74, hco3 14.
It's acidosis but Respiratory or Metabolic?
Plz answer it
🙏👌
Sir My question is that if any abg drawn by a 5/10 ml syringe using a 22G needle ...is this process right if not then what are the reasons behind... Sir Plz clear this concept .
Sir do we need to add potassium along with sodium in calculation of anion gap or should we include only sodium ?
if potassium is added normal anion gap is 16, if not then 12. that's the only difference
In bipap, how fio2 is becoming 24 in 1litre, 28 in 2lit ? Can anyone explain 😢 20 lit is for oxygen that i hv understood but rest?
Sir 🙏, while calculating expected anion gap for albumin correction why 2 is subtracted for each decrease in albumin. With decrease in albumin, anion gap should increase or decrease? Adjusted anion gap = observed anion gap + 0.25 x ([normal albumin]- [observed albumin])
albumin is the major unmeasured anion and contributes almost the whole of the value of the anion gap. So if albumin is low , expected anion gap also decrease ( means less unmeasured ions in the blood)
albumin corrected anion gap = anion gap +[2.5*(4-albumin)
that's actually saying 2.5 drop of AG for 1 gm drop of albumin.
And sir why can’t we classify the metabolic acidosis on the basis of AG
Sir, why are we comparing the anion gap with expected anion gap instead of comparing it with
Normal anion gap value I.e 21 +_2 while classifying type of metabolic acidosis???????
How can I get the pdf?? . .that link given in description not working
go to esbicm.com in downloads section
sir as you told saturation is a binding of hb + O2.
but in anaemic patient 4 gram. hb
saturation is 97
plzzz tell how is this possible
haemoglobin is saturated... there is no deficiency of o2 ... instead its total amount of oxygen carrying capacity of blood is reduced due to low hb... but the tissues demand remains the same, that's why patient gets fatigue.
Alveolar gradient = (713×fio2 ) - (1.25×pco2)
So if a pt having fio2 70% , pco2=47 then is alveolar gradient is 376 is correct or m I doing some mistake
Didn’t understand your question
Sir please tell how to check it is VBG or ABG
ruclips.net/video/DiHAwk2l2AA/видео.htmlsi=3EBn229aMDr_i1UN
Sir ph of 7.41
Pco2 48
Hco3 30
Sir what will be its interpretation
Sir one question you told in the lecture hco3 drop by one pco2 will drop by one to 1.5
But what about if hco3 increase then pco2 will increase by same proportion that is 1- 1.5 or any thing else
Please guide
The increase rate will be 0.5 to 1
Sir apka telegram account jis pe pdf available ho plz tell me
No … only ESBICM.com
This anion gap is very tough and I always get confused with this
practice that after listening , you will pick up.
why not mention BE , LA and hb levels
Fig heart fan💉🧠,❤️
Thank u
Which hospital wroking sir
Apollo
Sir, I am not able to solve one ABG.
Please help me in this regards.
Ph 6.95
Pco2 155
Po2 35
Hco3 22.5.
Though it looks like respiratory acidosis but as per your guidance, i calculated base line pco2 of 95 mm Hg, but is it Acute or chronic, I am unable to solve. Can you please help me??
Post on esbicm forums
Isn't albumin correction added to Anion Gap. Meaning low albumin will increase the anion gap right. You're showing that AG is decreasing instead of increasing with low albumin??
It’s actually contributing to unmeasured ions and hence anion gap … but if you have measured and found low , the expected and corrected anion gap will be further low .
Is it important to know anion gap
Any easy way to learn anion gap
yes , I have tried to explain in the lecture. you can refer any good book for that.
