Thank you for the tips.
What I am trying to do is to upgrade, especially now that I moved away from my home state. Plus, as a working adult, life has expanded quite a bit. I think realistically, the 103 is great when you are younger, but now that CF pateints can acutally branch-out and enjoy life more fully, we should be able to.
The process of getting the smaller vest could take a couple months or so, who knows. I think I am going with that route at this point. I am making a short trip back, and I am going to go without it. I will use my neb machine. If I do not feel as well as I hope too, meaning: I have a lung infection of some sort; then I think I will speak the airline and emphasize the cost, and need of the machine. I may still have the instructions, if I don't I bet I could go on the internet and get something, or request a copy. I have a larger suitcase that it should fit into.
You are a mom on a mission, that is fabulous.
Thank you so much for the pointers, I appreciate it quite a bit!
