Such a good teacher!! Loved this.

I have watched the lectures twice, and they are great.
My only concern is that I stumbled on them when I logged into the website, it doesn't populate in my app feed for whatever reason.
This really helped clarify and codify some vital teaching points for me, thanks again.

A must watch, I truly loved how she simplified using visuals. Thank you for that! I hope EMRap continues to provide explanations as this, where it combines both, the auditory and the visual portions.

Amazing stuff.. Help me please with PE pathophysiology based on your concepts of Hypoxic and hypercarbic resp failure. Most of my PE pts are hypoxic and are able to ventilate and actually have lower pco2 then normal. PE to my mind looks like your model of pulm capillary dysfxn with no perfusion to healthy alveoli. This should increase alveolar dead space and raise Co2 and leave PaO2 alone. Unless the pathophys in PE is actually dysruption to the alveoli-cap interface from inflammatory mediators and clots.. Please advise Thanks

I think you misspoke at 05:57. You said ..."proportional to the RESISTANCE..." when I think you meant RADIUS.

Small correction...flow is INVERSELY proportional to the fourth power of the radius. Great lecture series for review of ventilators.

Sudhir P. -

Jay both the items are in the numerator so this is not correct. A large pipe moves more volume than a small pipe...does it not? Just thinking this through. Stay safe!!

Excellent presentation! I honestly wish this was the lecture I was given back in med school for my pulmonology class.
