I'm studying to take my Step one next month and never understood this, after a youtube search on V-Q mismatch I stumbled upon this, thank you so much! It's so clear now, better late than never! :)
Jenny Gonzalez Glad we were able to clear up VQ mismatch for you- thanks for the feedback
See the whole series at www.medcram.com along with other top quality videos including reviews in pulmonary, cardiology, infectious disease, and hematology!
Thank you so much for all your videos.
I'm in my third month as a first year pulmonary/CC fellow and have been using your videos to reinforce concepts that during residency I found very confusing. You have such a talent.
Thank you
You got a very rare talent that many people dont have..thanks a lot...

ICU nurse here: hard to keep up with, but still very helpful. Thank you guys.
Blew my mind how simply it was explained! Loved the illistrations
ur lectures go hand in hand with your picture - you explain so clearly that it is like you are spoonfeeding us the exam answers :) so glad to be subscribed.
Incredible illustration, Doctor. Bravo! The best I have ever seen. Crisp, eloquent and to the T.
Came here to grasp it for nursing school... And DANG. This was fantastic! Exactly what I needed. Thank you!
Wow. ICU presentation today covering MOA hypoxemia. This was the only thing i had trouble explaining. Thank you!!
Glad it was helpful - thanks.
Straight forward, concise and in layman's terms. Very well done, thank you for your time and effort.
Legend. If only you were my lecturer! So clear & easy to understand! THANKS A MILLION!!!
You are a god! Pulmonary Physiology exam coming up & this explained it so much better than my professors rambling!
You have a great way of teaching. Simple and precise! Thank you!
Finally a well explain concise video with ways to apply this concept
These have been great, thanks for posting. Everything is clearer now!
I am a pulmonary hypertension patient and have to have a double lung transplant. This lecture really helped me understand what the docs are talking about when they say my pressures are at certain levels. Thank you
thank you for such a clear explanation of V/Q mismatch
Hallelujah !!!!!!!!!!!!!!!! May God bless you million times million. I completely understood the concept, I was so lost before i watched this video. :') Thank you
You are helping me get through nursing school. Thank you so much for these videos.
This is a really thorough and clear concise explanation of V/Q mismatch thank you so much!
your lectures are great I finally understand so easy to follow... I have been to several lectures on VQ mismatch over the years and could not get my head around it... I listen to your lecture and bang I finally understand it. I'm glad our Uni lecturer suggested to watch your videos..
Jason MacAskill Thanks for the feedback- glad the video helped clear things up
GREAT demo! Clear and informative!
this is absolutely amazing. I've been trying to understand this concept for literally hours. i get ittttt
Thank you for watching!
Way of your explanation is matchless... A big applause for you
Thank you
You explained things wonderfully! Thank you for making this topic simpler for me.
Fabulous! great visuals and clear instruction!
Very good explanation of quite difficult topics for the USMLE step 1. Thank you Sir.
Absolutely awesome! Why can't clinicians just explain it like this? Thank you ever so much for making study easier
Love the analogy of ' air goes in and out and blood goes round and round' - this is what I jokingly tell people my bachelor of paramedical science taught me. However, essentially keeping a VR and HR going is one very good end goal for treating acute patients, generally speaking. I'm sure you know where I am coming from. Peace
Dude! You are a rockstar at explanations!!
Fantastic explanation. You are doing great job!
Extremely helpful and concise. Thank you very much!
Love this series! I may pass this exam after all!
Very helpful! But one suggestion: Khan's professors are great at using different colors to help organize paths ways or thought. I would have appreciated that especially in the beginning of the video.
Doc am grateful for all your materials.have learnt a lot
Anaesthestist resident in Nigeria
I have stage IV COPD with VQ mismatch and PH and nobody ever explained what this meant to me. Thank you!! Now I realize why I must keep 02 on always and monitor with pulse oximeter.
Thank you so much.For the first time,I can say that I understand Hypoxemia.
Wauw, this is soooo incredibly helpful! My test is tomorrow and I have higher hopes now haha! Thanks a lot!! X
That was great. Thank you for your time in explaining.
this was incredibly helpful!! one topic of interest (may already be covered, havent looked to see yet) differentiating PA02 from Pa02 from percent saturation from Fi02, and the different pathologies impacting all of these values (CO poisoning, altitude sickness, methemglobinemia, etc)
Thank you! This is super helpful.
After reading over the same 3 paragraphs about 4 times in my text book, i bounced up this you tube explanation and i can finally read on. Thank you very much.

@Tye, Aa refers to alveolar-arterial gradient and the concentration of oxygen of both areas.
I was just diagnosed with this today and my head was spinning. Thanks for an easy to understand tutorial.
You can not be diagnosed with v/q mismatch... You can be diagnosed with pneumonia or asthma or anything else but not v/q mismatch...
Payden Aronson Interesting...I have documentation stating VQ mismatch from a Cardiologist and a pulmonary team. Had 2 right heart cats done and one was a stress cath ... I am not contradicting you, I don't know enough about it to say who is correct.
