I've been using 7% saline via nebulizer for years, usually just once daily and only when I get a bronchiectasis exacerbation. In my current exacerbation, though, they have me doing it twice a day, with huff coughs. It works great, like an "enema for your lungs." 🙂 I've found the saline is making me a bit hoarse. I use the Vest after my morning nebs. I have a feeling they're going to have me do this perpetually, not looking forward to it, but it beats being sick...
