I swear this changed my life. I NEVER get a single acid base question wrong anymore! Like for real. THANK YOU!
Aishima where madam?
I want to thank you for creating all these vids to help others. My brother introduced me to dirtyusmle and I have used ur teachings to teach my friend and she learns while I reinforce what i learned because of you. Teachers like u are what make the world better. I can honestly say that every single video of yours that i have seen has changed my life. When i pass my exam it will change my life even more, a better future not only for myself and for my family, but also for all the people i will be able to help one day. Thank you and please continue to make these great helpful videos!!! I ❤️ dirtyusmle!!!
I’ve been trying to learn this for so many years that I literally gave up and accepted the fact that I’ll never understand it. This video is brilliant! Genius! It changed my life, thank you!
BLESS YOUR SOUL!! i love u random guy in the internet who just explained everything i have to know for a test tomrrow, sending lots of good vibes to you man
I'm a newly licensed ohysician and this helped me tremendously. THANK YOU!
THIS IS LITERALLY SO AMAZING HOLY. you're an absolute genius
This was always such a hard concept for me in Med school! but this video has clarified it so much for me. THANK YOU SO MUCH!!!!
Where are you madam Devanga isee your contribution in Acid base balance obvious even me had help to know in detail
The best video I ever watched on youtube. I need not open books again to read about acid-base balance. Thank you very much sir!
you are my savior thank you for all of these videos your videos are the ONLY ones that get me to remember things
This is the best explanation what one could give to any acid base balance question :) . The best teacher for short tricks . Love from India 🇮🇳.
Hands-down, your most impressive video. This is an elite, creative tool
It’s very short and sweet and to the point where you get most of the questions answered on a test but this is only the beginning of this huge topic. Good for starters.
Thanks for making this concept ridiculously easy that medical school professors try hard and fail to explain
I also think of ROME changes (Respiratory opposite, metabolic equal) and just use your pH to know if it is acidosis/alkalosis
Thankyou so much for your amazing videos, as always
Quick info regarding the first example, we have to calculate compensation whenever we encounter Metabolic acidosis by Winter formula. (1.5 * HCO3 + 8 +-2) . so the example u gave is not compensated . Its Metabolic Acidosis without compensation
The math wasn't checked in the example. It's moreso just the method
If we apply winters formula in first example then value of CO2 should be 23 and here in example is 28 which is above normal so it becomes a mixed disorder, right ?
Exam day after. I can't tell you how thankful I am, that I came across this video. Thankyou so much! Do you have any advice for me? Biostat is a bit of a problem for me..
Used this today in rounds on the spot when the Consultant handed me the rapid ABG strip and asked me to interpret it… got it right and impressed everyone Cheers Dirty Medicine ❤️
Thanks I tried bnb and was confused ...you simplified a lot....the thing I couldn’t get in one n half hour u made it clear in 8 minutes
You deserve Noble price for all your contribution to medical education rather than those stupid med schools sucking all the money they can.
Thank you so much, man. I really never understood this one over the years. You really helped a lot of struggling students here!
Thank you for this Dirty!!! I have no words. Sharing your videos with ALL my friends. Love from Singapore!!!
You should create some sort of step 1 review program. You are awesome bro.
We might release a textbook if we can generate enough interest. It would NOT be all-inclusive (ie, it would NOT be like First Aid). It would contain the HIGHYIELD info from each section, complete with mnemonics, and then at the front of the book there would be a list of the top-100 most commonly tested facts
Hope you guys release it before august 2017.

@@DirtyMedicine hi! Where can I find your book?
@@DirtyMedicine Good luck
A good trick: Is there an anion gap? It is good to look at this BEFORE ANY OTHER NUMBER to save time. Because, if there IS INDEED an anion gap, then you 100% have an anion gap metabolic acidosis
Hi Dirty, I might be wrong about this, but if you use Winters formula to calculate the range of CO2 for compensation, this CO2 value should be between 33-37. However CO2 here is beyond this range, so theoretically speaking I don't think this is a compensation.
The numbers are totally made up for the sake of illustrating how the numerator/denominator change. The actual calculated and reference values are irrelevant for the purpose of this video.
MAY GOD BLESS YOU
You are a Gem! Some Heros don't wear capes. Thank you!
A 58 years old man was brought to the emergency with confusion and lethargy. His temperature is 36.7 C, blood pressure is 86/58 mmHg, pulse is 120/min, and respirations are 10/min. pH is 7.59, pCO2 49 mmHg and p0285mm Hg. Which of the following condition best describe his acid base status ? How to solve this when hco3 isn't given
Primary disorder: Metabolic alkalosis (high pH)
Compensation: Respiratory acidosis (elevated pCO2)
I just scrapped 4 pages I had written of high yield acid base concepts..this is all we need ..plus winters formula and the compensations...
This is awesome!! But I don't think this method works for some questions that force you to calculate using Winters formula. Cuz I ran into some of them and it was very annoying
oh my god dude thank you!!!!!! I spent so much time trying to understand it but u explain it within minutes 😍 ty
I think this is very simplistic for what step 1 wants us to know.
SUPERB EXPLANATION! I thought I have to sit with my slides, to understand, but this one was just on the go!!
GOSH THIS VIDEO IS AMAZINGGGG THANK YOU FOR MAKING MY LIFE EASIERRRR
This is the single best explanation I've gotten on this topic, thank you!
Oh Man. You are such a brilliant guy. No words to thank you. You Mad my day Sir. Stay blessed.
In love with your voice ! 😍 Also great video
One of the best video for interpretation of abgs .. thankyou ❤
i think the first example may be a little too simplistic. Yes the patient has metabolic acidosis. but then you should use winter's formula to see if the patient is being compensated with the respiratory system with 1.5*HCO3 + 8. This gives you a value of 35 (range of 33-37). Because the value of CO2 is much lower then expected, then the patient should be having a overlaid respiratory alkalosis and he is NOT compensating.... is this not correct?
Plus he did not take into account the anion gap from chem 7
you don't know how much this video was helpful, thank u so much
Love this. Can tell that your thoughts are systematic and organized. Thanks.
Hi, can you explain how the acid/base changes for aspirin overdose? I know in the early states its respiratory alkalosis and then late will be metabolic acidosis with anion gap, but how would you differentiate which one it will be in a question?
I love this. I’m done with steps, yet I rewatch this again. Thanks man!
The way you simplified it is just.. AWESOME!
Dirty, my king, all of our king, you have helped me understand something I never did before!!!
No wait.
It cant be this easy
I HAVE BEEN SHITTING ON ACID BASE QUESTIONS SINCE 3YEARS AND THISSSS :')
May God bles you!
You are a magician! I actually understood this. I am so jealous of the future gens who will sit for step1 because by then you will have so many more videos. BUT THANK YOUUUU
Simply amazing.. Never got a/b balance so easier. Thumbs up. Thanks
Thanks! I knew if I searched long and hard enough, someone would know of a way to help this sink in and make it easy to quickly figure it out in my head.
BRILLIANT. You, sir, are a genius.
What would you if you have HCO3 and pCO2 and you're asked to find the H+ concentration? What I did was use the Hasselbach equation to figure out the pH that way, and then I did 10^(-pH) to get the [H+]. I'm getting slightly confused though, if you have the H+ concentration then how would you make a diagnosis/deficit?
Love your voice. And thank u for teaching this in a simple way.
Everything I need to know in such a simplified way! Thank you so so much!
We all owe you big time, Sir! ❤️
Awesome!! Finally I got it! Thank you very much!!! God bless you!!
Absolutely genius. Thanks for sharing ❤
VERY VERY impressive....banged out 5 problems effortlessly
No bullshit straight to the point and effective! Thank you!
You are perfect! But I still have one question; If pH = 7.63 HCO3=26.9 CO2 = 25
We will call this alkalosis but respiratory or metabolic? How can we decide ? Or is it important to know the etiology in here ?? Thank for everything , I hope someone can answer me! :)
bump I'd like to know too
This would be a Metabolic Alkalosis with Compensatory Respiratory Acidosis
Answer this please
It is a mixed acid-base disorder since pH is high it is alkalaemia and carbon dioxide is low hence it is respiratory alkalosis and for this bicarbonate should be low for compensation to be exact three points below normal for acute respiratory alkalosisAnd 7.5 points below normal for chronic respiratory alkalosis but pH is high here so it is a mixed acid-base disorder of respiratory alkalosis and metabolic alkalosis and that also explains very high pH
Doc Thind Thank you for your answer
I didn't realize it was this easy this entire time, I never got this concept before!
Your explanation was very clear and easy to understand with good logic that'll make me remember it as well. Thanks a lot!! -Medico
Have to say amazing work with your videos
You've helped me A LOT. Please keep posting videos more consistently ❤
You’re genius!!! Thank you for your videos!
You are the best! Thank you for this!
Thank you for this video. I have a question: if we WERE talking about a mixed acid-base problem with a low pH.....then the values should theoretically be a inc denominator and dec numerator?
correct. Mixed Acid-Base usually doesn't show up on Step 1 for that very reason
The first real thing I truly understood about acid base 😅❤
Thanks Dirty medicine
I thought ph 7.35-7.45 normal CO2 35-45
deede1 correct ☺
you are correct. he is also correct. he is just using average values.
Still gave abnormal ranges in examples
This video is an easy method to never get a acid-base problem wrong, ever again.
You're awesome! I finaly figured out AB regulation,and with this short and simple video. You rock! 👌😄
Listen to me my professor made this fun and I still could not comprehend. The way you explained this is amazing and simple thank you so much.
Thank you for your medical lecture. I get a strategy of USMLE.
Boom, u made it so simple @DirtyMedicine… 🧡 4m 🇮🇳
Wow simply AMAZING, thank you so much you are something else 👏🏻👏🏻👏🏻
Thank u so much. I never thought I could ever understand the acid base balance. U made my life so much easier.
Bro I love you wallahi
I think I love you. Thank you for this!!!
This is better than that tic tac toe technique! Thanks!
Thank you so much! You don't know how much you have changed my life!
This changed how I look at everything thanks
Loved it but wht i get confused is the combined syndromes plz can u make a vid abt tht too
This is literally the best! Thank you so much💜
Vvvvvv nice lecture, I had a lots of confusion in this topic , now it solved
I must to say,ماشاءالله
You are great. God bless you
oh my god. i cant believe this. incredible im not going to miss any other acid base questions.
I love you. Thank you. I was about to throw my computer out the window. 5.5 weeks till USMLE ⚰
It's a very, very, very, very, very, very, very great. THANKS A LOT!!
You are a savior man!
YOU ARE THE REAL HERO MAN!
Please do videos for pharm and micro too !
We have a ton of videos planned. Stay tuned b/c they are coming!!
+DirtyUSMLE i have my exam coming up in july. any advice?
Some things you may not have thought of:
(1) Don't take a lunch break -- instead, take 10 min here and there. Eat protein bars and take a few sips of something caffeinated. Taking an entire lunch break weighs you down and makes you sleepy.
(2) If you are stuck on an answer, pick the obvious answer & don't assume they are trying to trick you. USMLE is all about presenting questions that have a clear, NON-controversial answer. Don't assume a question is trying to be tricky...they can only construct a fair curve with excellent, clear-cut answers.
(3) ...sort of a continuation of (2)...trust your gut. The brain in your stomach is smarter than the one in your head.
(4) On the night before your exam, make sure you get a good night sleep. I woke up at 5am that morning to intentionally make myself sleepy that night. Also, read the "Rapid Review" section in the back of FA, but don't study anything else. Within 24 hours, you won't learn anything new so just relax and don't get stressed, or else it will be detrimental.
+DirtyUSMLE thank youuu. Your videos are awesome 🤓
Can you explain what happens to pO2 during these changes ?
Life changed!!!! Thank you!!
Absolutely magnificent explanation I raise the hat up for you dude
Ammmaaaziinng! Excellent.
wow, this is a really clear explanation. Amazing. I never really understood this before. Thank you so much for this
my life has become so easy after this vedio , thank you
What about complex acid base disorders? Like when you have metabolic acidosis and a respiratory alkalosis ate the came time?
For yt algorithm. Hoping every med student finds this channel.
What about when the pH is normal? But there are variable numbers in the bicarbonate and pCO2?
You sir just made my life so much easier ! Thank you !!!!
You are the best ❤. Thank you for your videos, they are so helpful
