Check out Amy's blog... <a target=_blank class=ftalternatingbarlinklarge href="http://noexcusesnoexcuses.blogspot.com/search/label/News?max-results=20">NoExcuses Blog</a> She has a lot of information there, I think; find links for vest & Warwick (the CF dr. extraordinaire who was the inventor of the vest (both the HillRom as well as the inCourage systems.)
We have the HillRom 105 vest. I like it but I think it has it's drawbacks compared to what I have heard about others. If you get the HillRom ask about the vest that they call the Minnesota version (or something like that); it has better chest coverage. I want one of those for Emily. No matter how tight I make hers I think her upper chest does not get the coverage she should have. The hoses also pop off rather easily at the high frequencies we now use, so locking hoses are a rather attractive option I wish the HillRom had.
HillRom has GREAT customer service though and worked very well with our insurance company in getting our coverage issues worked out. <img src="i/expressions/face-icon-small-smile.gif" border="0"> We are on a 2yr program through insurance at the end of which we will own it, they will provide lifetime replacements on vests & hoses and will service the compressor as needed.
