Scoop is correct. I've had pneumonia 5 times in the last year. Hospitalized twice because of severity. Also, had Rhinovirus with it. Clearing the airways is the best thing. I use my nebulizer 3 to 4 times a day and my Aerobika. Because of the scar tissue in my lungs, I have from my chronic MAC which I've had since 2016, I am really susceptible to pneumonia and viruses. The bacterias get trapped and grow in the phlegm under the scar tissue. I wasn't diagnosed with Bronchiectasis until 11/24 after a hospitalization. I wear a mask whenever I go outside the house to help prevent breathing bacterias. Even then...some slip through. Airway clearance is key...
