Hi Toni. When I first came onto this Connect group hardly anyone was nebulizing the saline, and rarely did drs know to prescribe it. I had read a medical journal from France back in 2010 that stated that the 7% inhaled saline killed back MAC and was proven a good source of treatment. I mentioned it to all of my drs back then, and none had heard of it or would prescribe it. NIH here in this country, also did a study and showed that it took 7% saline to kill mac. This chart from NIH has been posted numerous times on this site so that patients could present it to their drs. When I first joined this group, hardly anyone was using the saline for lung hygiene. It was a sad, sad, group back then, as most everyone was very sick and had horrible, debilitating symptoms. There was a lot of crying and hand-holding. I harped on the use of the inhaled saline until most everyone that could get on it, did. The climate of this group has definitely changed over the years; our members don't appear to be quite as miserable as they were before, and many have stated that once they started nebulizing the saline; they started to feel much better. I just got back from my Mayo visit last week and I was taken off ALL antibiotics and my dr said that good lung hygiene with the albuterol and 7% saline was the most crucial thing I can be doing. Good lung hygiene is what we ALL should be doing if possible. I know that some on here cannot use the saline, but lung clearance is a must. I hope this helps.
