I have a Therapy Vest (American Bio Systems) from the late 90's. It is an adult size vest. I am 5'1" and was around 130 lbs when I was using it. It has not been used in the 8 years since I had my lung transplant. I am moving soon and do not wish to store it any longer, so I wanted to help someone who could not afford one. All I ask is that you pay for the shipping fees. When my insurance company paid for it, it was a $20,000 machine. I have no idea what it would cost today as it is an older model. Therapy vests aren't fun, but it did help, and I hope it can help someone else. I also have a portable therapy table and an IV pole I'd like to donate.
