Until I discovered this forum I didn't know that saline concentrations were available above 0.9. Now, informed and maybe wiser, a few days ago I sent a letter to my pulmo to wit: December 26, 2019

Re: Saline Inhalation Nebulizer
Dear Dr. Luterman:
Since beginning to use the Percussion Vest Airway Clearance device a little over two years ago I’ve been using 3 mL vials of .09% saline solution. I’ve never had reason to question the routine; indeed didn’t even know there were other concentration and quantity options.
More recently, I’ve learned that other bronchiecstasis/MAC patients variously use concentrations of 3% and 7% and 5 mL volumes. Those patients seem to do so predicated on the notion that since 0.9% is the salinity of the human body that an inhalation concentration greater than 0.9% is necessary to clear mucous. I also know that many, perhaps all, of these persons suffer more severe pathology than I do. However knowing that hasn’t dampened my curiosity about the more aggressive regimen(s).
So I’d like to impose on you to consider for a moment if there is any merit in increased saline concentration and/or volume in my clinical situation. I’ll try to make it as easy as possible; if your advice to stay-the-course as it stands now don’t bother to call. If the phone doesn’t ring I’ll take that as “stay put.” It you think it’s worth talking over briefly: 214-827-4363 .
In any event I’m looking forward to seeing you next May.

Well he just called and I'm gonna join the 7% club forthwith. This forum rocks!
