Calculating FiO2

[@DavidUnderwoodWVCRNA26]

Very Helpful and far easier than what was explained in textbooks. Appreciate you!

[@joyfrance565]

This was very very helpful! Well explained. THANK YOU! Bring more calculations

[@heathergasso5306]

This is a much better explanation than Prodigy and Apex combined. THANK YOU

Thank you so much. Deeply Appreciated for helping me to understand the concept of FIO2.

What if you had the FiO2 and total flow between 2 gases but needed to find the individual flow of each gas ? I was trying to work it backwards but can’t figure it out !! Thanks !!

[@complexnumbers64]

Say the flow of gas 1 is f1 and gas 2 is f2. Also say the fraction of o2 in gas 1 is x1 and in gas 2 is x2 (I.e. x of pure o2 would be 1 and of air would be 0.21) Say the total flow (which is known) is f_tot = f1 + f2 FiO2 = (f1*x1 + f2*x2) / f_tot So: FiO2 * f_tot = f1*x1 + f2*x2, with the left side being known in value You can then use f1 = f_tot - f2 and f2 = f_tot - f1 to get the right hand side to a single variable and solve it. For example for f1 it would be: FiO2 * f_tot = f1*x1 + (f_tot - f1)*x2 If you rearrange for f1 you get: f1 = (f_tot * (FiO2 - x2)) / (x1 - x2) Then you get f2 from f2 = f_tot - f1 Hope this helps!

You know sir, it's such an easy calculation when you're explaining it, but I couldn't figure it out for the life of me while standing at the head of the bed last week. Thanks a bunch for the video!

great song and beautiful place! where's it btw?

Got me going in circles, round and around we go.

[@mjonesCO]

Where am I going wrong? 0.6 Air 0.6 Oxygen I keep getting an FiO2 of 60% but my vent says 44% What am I doing wrong?

[@max-superdog2385]

great explanation sir .
