OT - Medical Education Videos-APNEA, COPD, etc.

I came across this set of educational videos on YouTube.
When you click on the link, scroll across to see other selections.

COPD, Obstructive Sleep Apnea, etc.

Apparently they are for education preparing for licensing exams for RT's and PA's.
Cool stuff.

Thanks JDS,
I watched the pulmonary function testing video right away. It was a bit primitive in terms of graphics, but had lots of good info.

Yes, but the drawings correspond to the actual PFT graphic reports that I got so in that regard, I found them very helpful.

I also found the videos on COPD and Asthma informative. I had never heard of carbon monoxide testing for either of these conditions.
