Story about a 5 year old and 18 year old with Cystic Fibrosis. Treatment and quality of life has significantly improved in the last 20 years!

I’m 20 and my girlfriend is 19. My girlfriend has Cystic Fibrosis and i invited her to stay over for a few days with me at my place. I was kind of surprised when she first told me about her disease. I know she has pretty low lung function and will have a lung transplant eventually. But how is the physiotherapy done and in what ways and how often? Do they usually do it on their own or do they often need someone to help them? Should I know how to do it with my girlfriend?
