Omg thank you so much for this wonderful explanation! I find this eqn a bit easier to understand intuitively if I see it as basically a version of Boyle's Law (P1V1 = P2V2) comparing the end-inspiration and end-expiration states. The pre-post and derivation slides in this vid help make this clearer.
Brilliant video - thank you. Would love to watch the Fowler's method video you mentioned too!
Coming soon!

Thanks for your comment and glad you found it useful!
It's a very similar argument for the shunt equation in terms of conservation of mass.
Thanks, great video, and useful comment at the end about situations on ICU in which ETCO2 might not match up with PaCO2 on the ABG.
Awesome video, very clear, especially the assumption at the end which cleared it all up for me (I couldn’t understand how we routinely measured PACO2)
This is not making much sense. I wish there was a practice question where dead space is actually calculated 😢
