@sma2 Unfortuately, many of us bronchiectasis and MAC patients have had to learn on our own. When I was first diagnosed in 2022, my doctor said I needed to do airway clearance but didn't specify how or any special techniques so I thought he just meant coughing. I wish I had known true airway clearance techniques back then because I if I had been doing it properly, it might have prevented my recurrance. Thank goodness for this forum and the wonderful people here who share information. Had I not found it, I might still not know proper airway clearance techniques and everything else we need to do.
