Wow, understood it in just 8 minutes and I found it so hard to understand my Professor who wasn't explaining it in details. Bravo
Glad it helped!
This helped me so much.. I could cry.
Thank you from the very apex of my heart.
JustPiichi
Apex 😂😂😂🤣🤣🤣
Lmao
You mean atrium?
jeshedu Yadav No , when you look at the heart from anterior try to look at the very lower left part (the left of the cadaver not your left) and the curved point is the apex , you can also google it
Makes you wonder if the people writing the textbooks are in the right line of work.
Ive reviewed this concept every few years and its never stuck, but I think it will now--the way you tied in the muscles and lungs to the features that cause the curve to shift was extremely effective! Thank you for sharing!
Thanks- We hope to make difficult concepts come alive. Glad to clarify the textbook info.
FINALLY A SIMPLE EXPLANATION!!
I couldn't study this curve for weeks and now that I'm cramming for my exam, this lecture helped a lot. Especially when I saw how the curve is drawn and which side is which with the factors affecting it.
Thank you so much!
Man! I’ve been struggling to understand that curve until I reached this video, it really helped me. Thank you very much.
Simply wonderful! I was struggling with this concept for days but
understood it in less than 8 minutes after watching this video, thank
you!!!!!
Thanks! I had forgotten the small details from undergrad, I also didn't feel like getting up to get my Biochem book.
If you're ever a Program Director, I want to be in your program. Goodness gracious how you take a ridiculously explained concept in medical school and make it my.....mastery topic.
No one explains it clearer than you do. Concisely great lecture !
thank you soooo much! I don't understand why lecturers at uni waste a whole series of 5 lectures going through something that can be explained well by you in less than 10 minutes :') absolutely wonderful
Apni Rimzolaa Thank you for the feedback
o my! thank you. this makes so much sense than the text! i read the thing for like 20 times.. and everything got so much clearer after watching this.
You have an absolute gift for explaining complex things in a easy to understand way! Thank you!
Randomly found this.. and I work with this MD. Very good doc.
Just found this channel while studying for a biochem exam... very helpful I was able to follow along with my note and this video just made things a little bit clearer for me!
NEVER EXPECTED THAT THIS COULD BE EASY TO UNDERSTAND!!!!!!
That actually really helped me! I normally avoid watching these videos because I just can't pay attention, but I somehow managed to focus and understand it. :D
I'm so happy right now.
This video clarified a lot for me. We are learning about it in nursing school right now and we know how important this will be in practice, so understanding it fully is imperative. Thank you for making the video!
Working on my NP and your videos have undoubtedly been my saving grace in pathophys. You are a wonderful, wonderful teacher and I'm sure I can speak for many of us that we are so thankful to have educators like yourself. Thank you!
+Natalie Hill Thanks so much, glad the videos have been helpful
Thanks for the question. I actually said that RBCs have a bulge in the middle because "they've lost their nucleus" (not elastic nucleus). Hope this clears it up.
Great explanation and diagrams. I know this comes 6 years later, but can you please tell me which program or tool you are using in the video? (I mean, the blackboard thing, how do do it?) Thanks a million for your help :)
Thank you! I was struggling to grasp this concept from my lectures and reading. Lifesaver!
In the past, I've always associated a shift to the R or L from normal as a pathologic process and not a naturally shifting occurrence throughout the body. Thanks for the clarification!
Thank you so much, this was exactly what I needed
Super straightforward and clearly explained! Thank you :)
Love the video, you have explained 4 big pages from my book in just few minutes, simply awesome! Really appreciate all your hard work. Thanks for helping.
Great video! Explained so clearly. I LOVE MedCram content! I've been making similar videos, inspired by you guys. Keep up the great work, MedCram!
I just watched 4 videos on this concept and this is the only one that my brain understood so thank you
loves these short and clear videos
You are incredible. Thank you so much for making this topic so much clearer and simpler than how I was taught. Very appreciative
This is what teaching is all about! Thanks, your knowledge kept giving me positive cooperatively in my brain memory cells.
As we have come to expect from this channel. Something that can be made to be understood in 8 minutes. Time to go put it into practice.
This is really helping me out on studying for an upcoming exam. Thanks a lot!
Beyond helpful and insightful! You have my very enthusiastic gratitude!
Victor Ruiz Thank you for the feedback
only spent 8 minutes to recall everything thank youu!
great lecture that really solidified some whys and wherefore for me. thanks!
I like the way you connect ideas together.
Tomorrow's my exam, helped a lot. Thanks!
Concise and clear. Thank you for your efforts.
This video is gold, pure GOLD.
Thank you so much! I was up last night trying to figure it out, and you made it so simple. :)
Sir....you are teacher of the teachers...lots of respect for your fablous teaching...
how amazingly explained the confusing concept...thank you so much
Invaluable presentation! Thank you, easy to understand and hopefully I'll do well in my Biology finals.
Excellent explanation! I am going to share with my students!
Well put; I finally got a grip, which is very nice, since I'm taking an exam in molecular cell biology on Saturday :)
Excellent! Love the high to low-level approach - very holistic. Thank you, Doctor.
Cory Allen Glad the video helped- thanks for the feedback
@megan moon.
They said it was because by the time 3 oxygens have bound to Hb, it is more difficult for the fourth oxygen to bind because there is only one space left to fill. It's because the red blood cell has to bump around the right way to fill that last space with oxygen. So maybe the actual affinity for the fourth oxygen is higher still but it is harder to make it saturated because the red blood cell with the free space left for the fourth oxygen has to bump into an oxygen correctly for it to do bind and that is why the curve levels off?
Excellent walkthrough, just found you guys while studying for a Biochem final. Enjoying the videos.
+Scott Hall Good to hear. Best wishes on the final
Thanks, simple, and easy to understand.
Your videos are the best thing that happened in my life!!!!!!
Thank you for sharing this information. It's a big help.
Absolutely terrific explanation!!!
Thanks! You just saved me so much time!
not trying to go for med school at all but currently in a biochem course and this video was very helpful. thank you!
Thank you. That much clearer than from my lecture.
you are amazing! thank you so much! that was exactly what every student needs to know, delivered in a clear and concise manner! :D
Ahhhh! Thank you SO much! This made the lecture I had yesterday make sense!
Thankyou very much for this. I have really struggled to understand this concept but your video has helped. I have my exam in 2.5 hours so I just had one last look!
Thanks so much! Great for visual learners, I definitely will check out your other videos!
Great! This was a terrific refresher! It's been a long time since I learned this in vet school!! Funny how the importance of glycolysis/cell biology/biochemistry come back to haunt you - if only I'd realized way back then, perhaps I'd remember it better!
Perfect, now i am ready to my exam in med school
This helped me visualize the curve much more clearly.
Elegant explanation on hemoglobin-oxygen dynamic shifts. Thanks a lot!
Great lecture! I have always had trouble understanding oxygen-hgb dissociation curve! Thanks!
My Respiratory Therapy Class from La Cité Collégiale would like to thank you greatly. Was wonderful for physiology class!
Very helpful and applicable to the Paramedic getting ready for Critical Care Certification exams.
Amazing presentation !!! Thank you
thanks ,you just saved me so much time ,and my concept is very clear now ,i think its very helpful for every medical studen
Thank you so much! Clear and comprehensive.
Wonderful presentation of the topics and beautifully explained like never before.......
These videos are amazing. I am a paramedic with aspirations of going to medical school. Im learning a ton!!!! Can you please do a video on increased vascular permeability secondary to shock. I transport a lot of patients on levophed and other pressors. Id like some a more indepth look at the A&P of whats going on at the cellular level.
Thank you, totally helped me on my Biochem exam. Thank you again!
Thanks so much! Helped me understand it more clearly. I will be watching more of your videos!
A great video. Thanks a lot , this is the first time I really understood the curve.
Excellent...better explained then in first aid for usmle
Excellent. great job with this presentation.
Wow, this makes so much sense now, thank you very much!
Very good explanation it was really easy to understand your video!!!
It helped me a lot!
Next week I will have my exam!
Thank you.
Thank you for this information , it has been very useful
Very neat hand writing for a Dr, others should take note!
EXCELLENT recap.
Very well explained. Thanks, was helpful to me.
My physiology professor sent me here, excellent video really solidified it for me!
+gymnastdancerstuff Good to hear- thank you
Wonderful. I am a Physiology Professor. Your video really helped me and my students better understand the mechanism of of -Hemoglobin dissociation curve. Thank you. In my opinion, visualization is a key component of the medical education.
Thank you- glad the video was helpful for your students
Very clear, excellent refresher
thank you you have helped me too much
Such an amazing explanation. Thank you so much sir
super helpful, keep them coming!
Wow this was really well explained thankyou verymuch I took plenty of notes
Super Clear and Easy to follow and understand. Best to do background reading and all will understand that much better.
THX!!
Very helpful, explained clearly compared to the 4 paragraphs in my text book. Thanks!!
Thank you guys! Great class!
Very helpful - thank you!
Thank you sir you saved my life for the next physiology test
Finally I got it. Thanks a lot sir.
Thank you from the very apex of my heart.
My MD told me my O2 hemoglobin saturation was lower than it should be, but couldn't explain well what that meant. Your lectures have been helpful in understanding what that meant.
Damn the French Glad the lecture helped- thanks for the feedback
Thank you soo much!! This was awesome!! I am studying for Boards and needed a quick refresher!! :)
Love your lectures doctor!!
Thank you, this made things very clear
