When I was in the hospital last month the RT had me put my vest on backwards... I use the short half vest that only blows up in the front so other then really smooshed boobs it was ok, but I can't do it by my self. I have also been told to do it on an incline board, head down, so gravity will help move the junk out... You are all much smarter and far more clever then you give yourself credit for... Way to be inventive!
