@tinaesims When I asked my pulmonologist about nebulizing he said absolutely not. Then I read Windwalker's message saying that her Dr thinks all MAC patients should nebulize 7% saline. I then found the above article that I posted along with a few others that I read and decided that I need to nebulize. Sometimes you will need to be your own advocate as some Doctors and nurses, though well intended, do not have the up to date information or are just plain wrong. I am a big proponent of research. Anyway, I decided my pulmonologist was dead wrong and began nebulizing. I cannot tell you what an immense difference it made in my breathing. I subsequently have made an appointment with Windwalker's Dr for a second opinion on my status... Sometimes you need to separate the wheat from the chaff. Good luck...Kate
