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!
great explanation.
Just what i needed, thank you so much sir
Wow ... Well explained, thank you
Awesome, congratulations!
Great! Thank you a lot!
Thank you!
Great video!! Thank you very much
Thank you so much! This helped a lot..
Brilliant
thank you!!!!
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
Thankyou so much
Awesome
The best ☺️
at the end of video only apply if the Fio2 does not change
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)?
what a boss!
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.
O2 is converted to CO2?
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
PAO2 = 150, R = 0.8, what is PaCO2 =??? And how did we get the 1.25?? thanks
