My cough had gotten some better by the time I got the nebulizer and vest. But the vest was the best thing for helping to clear my lungs as I could not get any congestion out of them until the vest. I think the two did help improve my cough though and now I do cough some daily but it is very much reduced from the continuous cough that led me to the doctor in the first place. It was almost non stop at one point.

What is your wife's diagnosis, does she have bronchiectasis, any infection, cough? Is she using meds other than the neb, and what is the prescribed med for the nebulizer?
It would be helpful for us to know, since our symptoms and treatments are so varied.
