7% Saline in Nebulizer for Mac

Hello dear group - I am on no meds for MAC (diagnosed more than 2 years ago) and I also have bronchiectasis. I was going to talk to my dr about putting me on 7% saline. But I have no problem at all with airway clearance whenever needed. I wanted the saline because I was under the impression it could possibly kill off the MAC as saline is a very unwelcoming environment for it. Is the saline simply to aid in loosing sputum? Input please.

I see the saline as keeping your lungs clean, it's an aid and the idea is to loosen mucus in order to expel it. The mucus is the host to NTM. I don't believe saline can kill it, but once you've got rid of the NTM, it helps keep them clear.

I believe it provides an inhospitable environment for further growth. The reason sea water is safe for swimming (for those vulnerable to NTM infection), is it has a 3% salinity, which is above the tolerance mycobacteria have for survival and reproduction.

My colony count went from over 200 down to under 20, once I started nebbing with 7% saline.
