I have pseudo in my lungs as well due to atypical CF (cystic fibrosis). You might want to ask your doc about TOBI (
tobramycin) that is nebulized twice a day for a course of 28 days on a month on, month off basis. It is very effective in keeping my colonies under control. Another thing to consider is Cipro orally, I can't take it but many with pseudo report good effects from that antibiotic as well.
The accepella is a good thing for you to do, it helps move the mucous around.
