When I was diagnosed with bronchiectasis and MAC, my pulmonologist prescribed 7% saline and albuterol to nebulize and also to get a flutter valve. I had never used a nebulizer in my life. I am to use the albuterol first with the nebulizer to open up my airways and then the saline to thin the mucus in my lungs. Not everyone is prescribed albuterol. Using the flutter valve afterwards creates vibrations in the lungs to help further loosen the mucus so it can come out. I’ve learned more about the importance of doing all this from the people here and a local support group than from my pulmonologist. In addition, I use an app on my phone called Autogenic Drainage after the above procedures that helps me cough up mucus. I didn’t cough up anything for 8 months, but now I do.
