Hi Helen,
Aerobika does help if you use it the right way. Watch YouTube demonstrations. I’m using it now as I write to you, hooked up to my nebulizer cup so I can do both at the same time. My doctor showed me how to connect them. Also a YouTube to show that. National Jewish Dr feels strongly you need Aerobika along with nebulizing 7% saline twice a day. Think of it as your job is Airway Clearance. Good luck.
Linda
