Mr. Prost, I enjoyed this very much! Nicely done!

With a size 6.0 ETT, you obviously have higher resistance and, consequently, more turbulent flow through the ETT tube. Therefore, P(lung) of the lungs would reach P(mouth) much later, with a size 6.0 ETT. P(lung ) would reach P(mouth) faster with a 8.0 ETT. You can see the inspiratory pause for a size 6.0 ETT is shorter than the inspiratory pause for a size 8.0 ETT. The lungs spend more time at P(mouth pressure) with an 8.0 ETT than that of a 6.0 ETT: therefore, a smaller tidal volume for a 6.0 ETT and a larger tidal volume for a 8.0 ETT.

Nice presentation..Very simplified , thankyou

Thank you

Thanks so much

i dont understand how you're getting the resitance to calculate flow. To calculate flow we got the change in pressure by subtracting Pmouth and Plung but what value are we using to calculate the resistance to divide.

Please, make video about forced oscillation technique in ventilation

Hi dear, in Simv mode if set RR is 12 and patients takes 14 breathes of his own... than how many breathes will receive the set vt?
