In this episode of Children's Hospital, there's a life changing opportunity for three year old Oliver Pulo who suffers from a rare form of dwarfism and has severe breathing problems. Ollie has been breathing through a tracheotomy for most of his life and needs an oxygen tank 24 hours a day; he has never been able to speak. Mum Vicky Rushton has to monitor the tank and change Ollie's tube every day; "I find it heartbreaking seeing all the other kids having a lovely time running around and laughing. He doesn't understand just how restricted he is” she says.
