Jessica is 9 years old and has Cystic Fibrosis. She had a difficult start in life as she was in heart failure at birth until open heart surgery at 10 weeks old. Each day is a struggle where Jess does at least 2 hours of intense chest clearance and on top of that she has to be active physically, for this she does at least 6 hours out of school activities and inbetween doesn't sit still. Jess works hard to stay as healthy as she can but......... an oscillating vest would dramatically increase her health and life expectancy in turn keep her out of hospital as much as possible.
