Summary
Brief summary
The purpose of this study is to determine whether correction of low nighttime oxygen (O2) levels and/ or high carbon dioxide levels in patients with cystic fibrosis improves their quality of life. The treatments being used overnight are (1)O2 (2)pressurised air which assists breathing (non-invasive positive pressure ventilation, NIPPV)
