Hi all...I use the vest now, even though I am vented. Wierd to get used to at first, but I like it. Yes it jiggles me around, but it works especially when I am sick. The crap that I suctioin out of my lungs after a treatment is unreal sometimes, it's hard to believe that much crap could reside in my lungs. I use it for 20 minutes twice a day, on varying frequencies. At first, I use a lower frequency like 10Hz, then I go up to 14 Hz after 10 minutes into the session (usually have to pause to suction myself). I use my nebs prior to the vest to open up those airways.
I too have a port, but there is a good way to help minimize discomfort, especially when it is accessed. Use a square of memory foam, you know, the stuff that the Tempur pedic is made of, cut an indentation that matches your port size, put it on under the vest and turn the vest on...you would be surprised how little you feel the vibrations on your port! Also, if you call Hillrom, they have a similar square of foam made of the same material that they will send to you, just call them...at least that's what the RT said to me when he set me up. I happened to have a square from my old mattress cover handy and improvised. You are right though, without the padding, it is uncomfortable.
I live with my mom who has arthritis in her hands so it is difficult for her to do the CPT. In the hospital, they usually do the CPT, works well too and they tilt me on my head LOL!
The pressure settings are adjustable...I know of someone who has Lou Gherig's who uses it on 1, the lowest pressure there is (I think the machine goes up to 6, usually used with a full vest) and she barely tolerates it. I am on 2, my muscles are pretty fragile at this point. The puffiness of the vest is t he hardest to get used to...also, if you have a trache, I have to adjust the vest differently or the thing vibrates right up next to my trache and gets very uncomfortable.
I guess, all in all, I am doing better with the vest than without...as everyone has said, it is a matter of preference and there are alot of devices out there that help loosen secretions too (ie flutter device for one, havent tried this one) I also like the portability of the thing, goes anywhere with you.
I hope I have helped and not confused you...Hugs, Jenn <img src="i/expressions/face-icon-small-smile.gif" border="0"> (the other Jenn)
