HiVictoria3.Good advice frank

Has a resistence from 1-5, creates a flutter when you blow out, try to blow out as long as you can. I hVe one in the car too, i use it as iam driving, that way i get my time in doing that Exercise!

I use the Aerobika, i had ordered the Air Physio and it was a waste if money, had to have though because if all the build up on facebook🤦‍♀️ for me, this works much better.

I have one I bought a few months ago. I don't know if I am using it right or enough. Seems to help some.

Always consult your doctor. It would depend really on your lung condition . For me, I cough up blood if my lungs get inflamed ,and these devices make me cough up blood …the pulmonologist told me to stop using them. A lot of these items have not gone through the “double-blind placebo test” Which means there’s no studies done on them to their effectiveness…so who knows for sure.
