@linda1334 I’ve had my afflo vest for over a year now, and although I am guilty of NOT using it on a regular basis, only when the mucus is thicker and harder to cough up, maybe during an exacerbation or infection. The only way it seems to work for me while using it is to incorporate postural drainage. I never experienced a good or great result, only minimal results but I guess I feel something is better than nothing. I’m totally convinced though through my experience that you have to lie down, to defeat the effects of gravity working against you. I also love what scoop mentioned, that it was generally made for CF patients, specifically children when their lungs are more pliable and younger. I also do a bronchodilator and 7% before I do the vest. I CANNOT see or understand the logic that you have to use steadily or repeatedly for awhile to see any effect. That makes no sense to me. If anyone can explain it to me please do, I’m all ears. Thank -you.
