Last time I was at National Jewish, they gave me a new type of nebulizer called an AeroEclipse; it is a reusable breath actuated nebulizer. Supposedly medication is delivered on inspiration only and I guess it might deliver more medication into lungs and or protect the environment and or just make us NUTS! As if that weren't enough, the aerobika can now be used with a manometer. The manometer is a green, yellow, and red attachment that you put on aerobika and it is used to provide visual feedback when you exhale (so you know that you are exhaling correctly by staying in a green zone)!! Anyway, I couldn't get the darn thing to work … so am returning to the good ole' Pari nebulizer used with an aerobika that has no such strange attachment. I guess it is the newest thing in nebulizers but I am an old dog and incapable of learning new tricks and thus, having an impossible time with it. That you, with all your knowledge, has never heard of it makes me happy because it reinforces my belief that this new accessory is not a "must have"! I have had some fluttering problems with a regular nebulizer in the past so don't need something else that can go awry.
