Airway clearance is on of the pillars of managing bronchiectasis,
so a pulmonologist who does not mention it is not familiar with the current standards of care. This is not uncommon. In spite of the impression you may get reading here, bronchiectasis is a rare condition. If want the best care to stay healthy fot the long term perhaps it is time to seek a doctor who regularly sees bronchiectasis and MAC patients.
Do you have options for seeing a different doctor?
