I use VibraLung, a handheld device recommended by my pulmonologist. Instead of a vest, because it does not shake your ribs, vibrates only in your lungs. Effective and only takes ten minutes. I use it after nebulizing. But when I got it, insurance didn’t cover it. I paid, but so worth it to me. I took a picture of the device and the rechargeable base. (Using twice a day, it needs to be plugged into a wall outlet every couple of weeks.)
Good luck sorting through all your challenges.
