There are two, that I know of, different kinds of percussors. One that Transplant Mommy mentioned does run off a compressor. Some hospitals use them. The hand held part is a small round shape hooked to an airhose that connect to an airsupply. The kind you, Jazzy's Mom and I are familiar with are the all electric kind. We too had one that sounds like what you had. They called it a jackhammer style. It was completely vertical with the cup that pumped up and down. The G5 we have now is quieter. In the hospital they have the flemfighter, it's on a cord attached to the machine on a stand. That webssite shows it.
It certainly sounds like your cousin is lucky to have you looking into things for her. It can be a bit overwhelming for both the family and patient no matter when the diagnosis is made. But now, you know what is wrong and treat it. Tell your cousin that exercise is a really good thing. If she can keep up with volleyball then go for it. It will help her to clear her lungs. The young man I mentioned from the boards here, he plays in the marching band.
Much luck to you in helping your cousin get what she needs.
