Thank you for posting this video! I´m med. student from Czech Republic trying to study for become M.D. in NICU.
-
A number of Hertz IS a frequency.
-
when she said "decrease frequency" she meant hertz, right? just trying understand the whole oscillator concept, because i thought you wouldn't want to adjust the hertz too much since you can add a lot of tidal volume if you decrease it too much and cause volutrauma.
-
larger the amplitude blows off more CO2. acidodtic decreases pH not increase pH. small slipup =P
-
she means if the PO2 is low, and you have an optimal lung volume on the X-ray, you either increase FIO2 or the MAP.
-
nice explanation thanks!!

thank you so much for this video. we are having a test this week, and this helped a lot! but when you say if you have optimal lung volume to either increase FIO2 or mPAW, why not maintain current settings? what is reason for increases?

Typically, we change amplitude to affect the PCO2 first, that will usually make the necessary changes to the blood gases, however, if more change is needed, we will then change the frequency. You get a bigger change in Vt by changing your frequency (Hz)

Blooddudemagic: You are right, after you have achieved optimal lung volume, you should either decrease MAP or FiO2. It was a verbal slipup by the student. Otherwise, she did a nice job.
