Precise and up to the point 👍 great work
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.
Wow. An amazing breakdown of this seemingly absurd equation. Thankyou!
Just what i needed, thank you so much sir
great explanation.
Awesome, congratulations!
Great video!! Thank you very much
Wow ... Well explained, thank you
Great! Thank you a lot!
Thank you!
Thank you so much! This helped a lot..
thank you!!! better than memorising it !!
you’re indeed a man of your words #Dr.Ani John on RUclips, 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
thank you!!!!
Thankyou so much
Brilliant
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)?
Awesome
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.
The best ☺️
what a boss!
at the end of video only apply if the Fio2 does not change
O2 is converted to CO2?
PAO2 = 150, R = 0.8, what is PaCO2 =??? And how did we get the 1.25?? thanks
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.
Had the same doubt after watching it ? Do you know how to convert it ?
@@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
@@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
