Yes I got Volara system in late fall after NJH doctor’s recommendation and Hillrom’s appeal to my insurance. After about two months of using it only at night ( faster that separate sodium, aerobika and vest) on medium pressure I started having chest pain and tight chest. I did not think first it could be the reason so I went through heart testing and some pulmo test. All was good. I contacted my doctor at NJH. And their answer was it could be caused by the changing air pressure pushed to the lungs. They advised to restart using it after the pain is gone -and it’s gone since I haven’t used it for the last two weeks) and then restart using it on the low setting. I am not ready to do it yet. Anyway you can have the volara system for the trial period. Summing up I think it is a convenient device to have as a back up may be when you are sick. We want to have whatever is available and help so I guess that’s why I got it. But generally for me it has not been very useful so far and I don’t use it to its full capacity for sure. I might even return it. I would say try it and then decide.
