Ventilation Dynamics Part 6: Flow Rate (V) , Tidal Volume (VT) and Inspiratory Time (Ti)

In Part 6 of the Ventilation Dynamics Series, George covers the relationships of Flow Rate, Tidal Volume and Inspiratory Time and how certain changes in one or two of these dynamics affect the third.

OH MY GOODNESS!!! The lightbulb just came on! Thank you!

[@GeorgeORRT]

Nice!

[@peggysnyder1577]

Thank You! Well explained! Gave me different ways to look at Flow Rate, I Time, and VT, and how they affect each other. :)

[@joditrue3912]

I've been struggling with the Vt, Ti, V relationship and the car analogy really helped. Thank you.

[@user-xn5oh4ih5z]

Thank you very much! You are the best teacher ad guru!

[@kseniiachurilova9112]

Amazing explanation! Got all my questions explained! Thanks a lot!!!

[@rajvindersingh7518]

Brilliantly explained by George ….

[@elfoo8663]

You helped me alot today sir. Thanks a bunch.

[@anbudev1689]

It's very easy to understand . Thanks a lot.

[@carissagagne3013]

You are a lifesaver

[@GeorgeORRT]

Thanks, Glad I could help

[@zamokuhlesikwambane3026]

Thank u it was well explained and amazing

[@vishnunarayanan5040]

Nicely explained…How do we calculate PEFR and PIFR.?

[@sinclair657]

Thank you

Thank you very much ❤

[@user-xn5oh4ih5z]

Thank you very much 🙏

[@hilliarysylvestre3580]

Excellent example

[@nargizsafarova9989]

thank you.

[@beckybarnett2066]

Thank you!

[@GeorgeORRT]

Thank you

[@tejashvaishnav]

Very like sir ,
Thanks

[@surajchandrakar4398]

Thank you sir

[@charlesmoteopeny8733]

good explanation

[@chethanningappa]

@12:26 if Inspiration time tidal volume decrease then flow decress = V= (0.5/0.1)*(60)= 30lpm, (V= 0.5/0.2)*60= 15 LPM. please confirm

[@tomcruise9317]

So if flow increase insp time decrease.....i.e this less time is enough to take 500ml tv ......normal pt .5 lit tv and inspirator time is 2sec so the .flowe anound me is .25lit per sec crt sir

[@chethanningappa]

how do I know the flow rate of the patient??

[@BGG137]

Thanku sir

[@muhammadimamrafi5288]

Sorry sir, how to calculate the VT of patient? 'cause we can't consider the VT of patient is always 0,5 L. But, thank you for your video

[@GeorgeORRT]

That was just an example. We can only estimate the Vt of the patient at the bedside and that is based on their ideal body wt.

[@adeemsalman2048]

dear dr.... other simple way for calculation Ti=0.06XVt(ml)/FLOW(liter/min)..
also from same equation FLOW(liter/min)= 0.06Vt(ml)/Ti .
0.06Vt=FLOW(liter/min) X Ti.
very simple mathematics....
YOUR EXAMPLE FOR FLOW, SEE BLOW
flow = volume /time example for that ..as you pour out water in to a mug ,, the more flow the shorter time, and the shorter the time the more volume. THANKS.
