I was diagnosed with BE 10 years ago and about 8 months ago tested positive for Pseudomonas. I only started nebulising with saline 7% six months ago when I became a patient at National Jewish Health. I produce a quarter to a third cup of mucus after nebulising.
After nebulising in the morning, along with SmartVest, I block up with mucus a few times a week in the afternoon. If I lay prone for 5 to 10 minutes, while doing yoga (stretching arms back and forth and side to side and raising and lowering legs, all the while on my back), I bring up quite a bit of green mucus with huff coughing, which I assume is the Pseudo that is colonized in my lungs.
What I gather from the doctor is that Pseudo treatment is hard on the body, and Pseudo, even if cleared by treatment, often comes back.
