@lweirdo1 , I have never used Albuterol. However, I believe it helps relax airway muscles in the lungs to treat bronchospasm. I nebulize saline to add fluid to scarred airways (from bronchiectasis) to help flush out phlegm and mucus that may harbor bacteria. I use 7% saline because studies suggest that 7% saline may kill MAC, and some other types of bacteria, or at least help keep their levels down in the lungs.
