Hi Katherine and all,
I don't know if I'm a great one to talk about the Aerobika but here goes. I started using it a couple months ago. My pulm. Dr told me to get one and I did and followed the YouTube instructions on how to use it. I was supposed to use it twice a day but (making excuses here) with some traveling and putting one house on the market and remodeling the new one I haven't been the best. I have a mild case of Bronch and Mac and I don't always cough and I never cough up anything. The only change I have noticed so far is when I lay down on my back I don't have a coughing fit like I use to. At my appt this week I met with a respiratory therapist to show her how I was using it and she corrected some things. I'll see if that makes further improvements along with using it regularly. Since I don't have a serious case I may not be the best person to make a recommendation. I will see how it goes over the next three months. I'm having a CT scan at that point and will hopefully see if there's been any changes for the better. I'll let you know.
Janet
