proverbs3 - in my humble opinion TOBI shouldn't be taking you that long; it takes us about 22 minutes, which is slightly less than what you said but I know what you mean about the mornings. 8 minutes is a lifetime when you are trying to get two girls out the door for school! Oh, and Albuterol takes us about 6 minutes.
I wonder if your compressor and/or nebs need looking at? Perhaps the compressor is going out or needs a new filter, etc. and maybe your nebs need to be replaced, or cleaned like crazy? I'm sure you are doing everything you possibly can so I hope I don't sound like I am questioning your ability. I don't know the brand of the compressor we are using, but we do use the PARI LC Plus nebulizers for everything.
Emily - I've been looking into the e-flow as well. Do you use it for multiple meds at one sitting, and do you clean the head between meds, and if so, how (i.e. rinse with distilled water or soak in alcohol, etc.). The reason I ask is because as it is now, lets say we are doing 4 total treatments in one sitting for Katy. I just have the nebs lined up and swap them out, and she doesn't have a chance to wiggle away! If I had to say, "okay, sit there for a minute while mommy cleans out the e-flow and loads the next med" I don't think I would gain any time overall because she would definitely bolt. Does that make sense? Thanks!
