The Davenport diagram illustrates the relationship between plasma pH, bicarbonate concentration, and partial pressure of CO2. For tutoring, click here: lancemillerphd.as.me/
@@LanceMillerPhD Hello Sir. I'm a Brazilian studing medicine in Argentina. Would you allow me to make an spanish and portuguese version of it? If so, I may need alter the graphics to those languages too.
I don't know how you have so few subscribers, your videos provide the most concise explanation in a ridiculously straightforward way. Thank you for all your hard work!
Very well explained Sir...I thought to mug up the graph but then I saw this video and... Now such a smart explaination can be easily retained in my memory for long...Thanks a lot.
This is definitely a great explanation for this complex diagram. I just want to correct that with a metabolic alkalosis the body could not regulate the body pH by decreasing the respiratory rate. This is limited by the need of oxygen. And thus a metabolic alkalosis can only be compensated with another metabolic process.
I have to study the Davenport diagram but I don’t understand something about it. I hope you could help :) The text states that when the concentration of H+ increases by 4 mM, the pH of the blood will increase ( which I understand ). Then the text states that when you only use the closed system, a line showing the gradient of the ‘ buffer concentration ‘ shows the new pH concentration when you increase hco3 by 4 (from 24 meq/L to 28). Then the text ends by stating the pH is now 7.1 with the H+ increasing from 40 nm/L to 80 nm/L . I hope this makes any sense and that you can help. Thank you very much in advance. Marissa
Hi Marissa, that is a great question. pH is a measure of the hydrogen ion concentration [H+]. So, when the [H+] concentration increases the pH decreases and the opposite occurs when the [H+] decreases. HCO3- is an important buffer of H+. So, when [H+] increases in the body, HCO3- binds or buffers the extra H+, which leads to a decrease in HCO3-. The opposite occurs when H+ decreases. So, plasma HCO3- concentration is useful in determining the level of acidosis (increased H+) or alkalosis (decreased H+).
this is amazing, the only video on the internet that can explain it correctly
Thanks.

Great video and wonderful explanation. I never understood this until now. Thank you!
I‘m so glad i cam across your channel, it‘s gonna save me in my Physiology exam !
You sir, are incredibly awesome. THANKS!!

Thank you, I appreciate the compliment and that you found it helpful.
Amazing
I almost finish all videos relative to renal system ,which is more clear and more easy
Thank you so much
thanks for the simple yet effective explanation. iam so glad I found this video
Thanks, I’m glad it helped.
Such informative and great video... thanks sir! everything is clear now!
Very good explanation - simple and understandable. Thanks!
Also the best explanation that I've ever seen

Extremely helpful - Thank you!
Excellent video. Thanks for sharing.
Such a great video! Thank you
very helpful video that explains this topic quickly and easily
Simply an amazing video! Will share with my medical students today.
Thanks!
Thank you for this. Very easy to understand. Could you please explain the use of this as well, in real life / clinical situation
thanks sir .
Awesome explanation
Best video explanation of the Davenport diagram I have ever seen!
Bro u made me understood so easily in small vdo, which I couldn't understand thru long vdos ,thnx alot more power to you
Glad to hear that.
so helpful! thank you.
your video it´s amazing, thank´s!!!! it help me a lot!
Glad it helped!
Super helpful.
wow You made it simple
Excellent presentation !👍👍👍
Thank you! Cheers!
u deserve like and a kiss :D ..thank u for gr8 explanation
Are u female

This is a really nicely made video - thanks!
please post more videos We Need You!!!
Very nice
Excellent very well explained
Glad you liked it
Fantastic!
Many thanks!

Fantastic
Thank you so much 😀
Thanks for this quick rundown. Perhaps you could include buffer lines next time.
Great idea!
Thanks dude.

Hi Marissa, when you say text, what text are you referring to?
Found this on a uworld question and freaked out honestly
Can someone explain how the pH drops when HCO3 is low or why when HCO3 is low, the pH drops?
Hi Marissa, that is a great question. pH is a measure of the hydrogen ion concentration [H+]. So, when the [H+] concentration increases the pH decreases and the opposite occurs when the [H+] decreases. HCO3- is an important buffer of H+. So, when [H+] increases in the body, HCO3- binds or buffers the extra H+, which leads to a decrease in HCO3-. The opposite occurs when H+ decreases. So, plasma HCO3- concentration is useful in determining the level of acidosis (increased H+) or alkalosis (decreased H+).
