I also have used the Pari pro neb and the Pari vios, and do find the pro neb to be faster. Of course that’s because I believe it puts out more psi from the compressor than the vios does. I tried the sprint cups, and yes it did only take 5 or so minutes, but I found that it didn’t seem to work as efficiently and effectively as the LC plus or LC star neb cups. Both made by Pari. Now a lot of this I think depends on how much mucus we produce AND how severe our BE is. If it is in the upper lobes or deep in the lower lobes, the ladder of course would make it harder to expel, and harder to get the medicine to. It really sucks we all have the bothersome devastating disease, but I pray we can all make the best of it. And LOVE the fact that we all have each other to help us during this difficult time.
