I would like to add a mid-day CPT. I know a lot of you guys do that; but, I get NO benefit from using my vest without a neb....I just feel there is no benefit to doing that. Those of you who do a mid-day CPT, do you do a neb with it and if so what. I am wondering if just doing sterile saline would be helpful. I don't really want a mid-day HS or anything like that. Suggestions would be great.
