嚢胞性線維症
Bronchiectasis may lead to acute hypercapnic respiratory failure (AHRF), and NIV may be used similarly as for COPD. This is particularly the case where the underlying cause is cystic fibrosis. Cystic fibrosis also causes high volumes of sputum (phlegm) which may require specialised physiotherapy assistance and sometimes the insertion of a mini-tracheostomy to clear this.
