This is THE BEST explanation Iv'e ever come across for this equation. Just what I was looking for, thank you so much!! Now the numbers all make sense, I don't have to memorize a bunch of nonsensical variables.
Why do we subtract PaCO2/R? Like why do we subtract the O2 taken up as it occurs later and shouldn't it be just the first part showing FiO2(Patm- PH2O)?
you’re indeed a man of your words #Dr.Ani John on TH-cam, after purchasing and using his herbal product for HSV2 I was totally cured permanently within few days. Thanks to #Dr.Ani John for the fast recovery
This video is brilliant. But you can't forget that you cant just use the molecular 0.8 CO2 in the equation , because you are talking about partial pressure (O2 consumed = 0.8CO2 which is different from pO2consumed = pCO2/0.8). Remember: partial pressure is different from the number of molecules. You have to convert it before write in the formula.
@@dr.allwyndsouza5246 yes! You have to use the "PV=nRt" formula. Just use the constants in one side of the equation and consider the volume equal to both gases (alveolar volume) (p1/n1 = Rt/V). So p1/n1= p2/n2, which is the same that p1/p2= n1/n2. Now you have that pO2 consumed = pCO2*1/0.8. :) Hope it helps
Thank you so much for the video. Could you please send a source I can use to understand the full alveolar gas equation? I have seen other forms of this equation that are more complicated.
Precise and up to the point 👍 great work

Did you find an answer?
Wow. An amazing breakdown of this seemingly absurd equation. Thankyou!
thank you!!! better than memorising it !!

at the end of video only apply if the Fio2 does not change

Had the same doubt after watching it ? Do you know how to convert it ?

@@vinitdasilva wow thanks for the reply. Now I get it. In our medicine book also they have not mentioned this aspect of the equation.
@@dr.allwyndsouza5246 which book do you use
great explanation.
Wow ... Well explained, thank you
Great video!! Thank you very much
PAO2 = 150, R = 0.8, what is PaCO2 =??? And how did we get the 1.25?? thanks

Awesome, congratulations!
Just what i needed, thank you so much sir
O2 is converted to CO2?
Thank you so much! This helped a lot..
Thank you!
Thankyou so much
Brilliant
thank you!!!!
Awesome
Great! Thank you a lot!
The best ☺️
what a boss!
