I have a sidestream, not real sure where it is right now, oops, but it makes it a little faster but the partical size is bigger which makes aborbstion less, I didn't know you are only sopposed to use it for pulmozime though, i have used it for saline, albuterol, pulmozime, tobi. Probably shouldn't have done that. I haven't seen my sidestream in a while, i think it fell behind the desk i keep all my med stuff at, i should probably find that. Thanks for the tip.
