The budesonide is a premixed vile 0.25 mg/2mL. As I said in my initial post, the Tobramycin instructions say you must use the PARI-LC kit. Today after 30 mins of doing the Tobi part of the treatment it did not appear any of the level was going down. I finally changed it to a basic type of neb med cup and it went down. The mist would come out of the mouth piece so I just don't know why it was not being used up. I looked at the innospire Go and they are $250 but if I knew if it worked I would invest in it. So do I understand it correct... you use the innospire Go regularly. Also what is the old green machine?? Thanks for the input.
