Here I am preparing for my cardio/resp exam by watching a UCSD resp phys video almost a year after being royally rejected from UCSDSOM😂 I shall try again during residency. A girl just wants to move back to San Diego, is that too much to ask?
I wasn't satisfied with the depth of the information regarding the relaxation pressure-volume curve. Why is it called relaxation? Should I think of it as forces opposite of the recoil forces for the lung to be in a relaxed state? When are the forces muscle dependent, when are they passive?
"This (the surfactant) reduces the pressure around the capillaries in the alveolar wall, and when you reduce the pressure around the capillaries, that tends to cause edema fluid to move out. Therefore, if you reduce the surface tension, you reduce the tendency of the alveolar edema to occur." Am I missing something here? This doesn't seem to make sense. How can you reduce the tendency for alveolar edema with surfactant when you said that the surfactant causes fluid edema to move out?
I know the comment is 12 years old but somebody else might have the same question, so what I understood is that the 'This' in the quote actually references the surface tension, not the surfactant. So it is the high surface tension that ultimately causes low pericapillary pressure and alveolar edema, while surfactant counteracts this.
How lucky we are when whatching and listening to his lectures...
we can feel the love that he pass through these lectures, thank you so much knowledge!
5 day until exam and i just started learning this subject by marathoning this dude's lecture
haha I'm glad I'm not the only one. I am literally in the exact same boat. 5 days until exam and powering through. so painful though haha
Great lecture from a legend in respiratory medicine.
Great lecture from a legend.......
great lecture by expert.....improve my lot of understanding about PV curve.
Dr West is the man.

Dr West. Excellent Tan.
Thank you for an excellent lecture!
Absolutely brilliant

thanks sir please only explain again hysterices phenomenon
fantastic , amazing , great sir
This was very helpful, thank you!
LOL 26:23 No matter how long you are in medicine, there are just some words that always kill you!

Very informative
I am now breathing manually 😂
Shouldn't there be a 2 instead of a 4 in the Laplace's law?
normally, but since there are 2 surfaces you multiply by an overall factor of 2.
Thanks! This helps so much
Thanks
I still don't understand hysteresis
Thank you, thank you, thank you!!!
erm~~congratz??
Thank you really! :)
i love you
