There are so many and I have watched so many! Airway clearance remained mysterious to me for quite some time. What made a giant difference for me was adding hypertonic saline, which helped immeasurably. I finally had something to cough up.

I suppose the very first website I found on the subject is among my favorites. Even then it takes time to master and figure out what works for you. Adding the aerobika also very helpful. https://bronchiectasis.com.au/physiotherapy

The other memorable airway clearance video was posted by @becleartoday , but I do not remember his name. He's based in NYC, kinda nutty, with dyed blonde hair, with tats and piercings. Very engaging effective presentation not to mention memorable! He refers to his work as complex physical therapy. 100% agree!
