In cystic fibrosis, what is chest physiotherapy used for?

• A. To strengthen chest muscles only
• B. To mobilize mucus from the lungs and reduce infections
• C. To replace antibiotics
• D. To diagnose CF

Answer: (B)

Chest physiotherapy is an airway clearance technique used to mobilize thick, sticky mucus in cystic fibrosis so it can be coughed up and removed. In CF, mucus blocks airways and becomes a breeding ground for bacteria, leading to infections and reduced ventilation. CPT uses percussion or vibration and postural drainage to loosen secretions, making it easier for the patient to clear them, improve oxygenation, and reduce infection risk over time. It isn’t meant to strengthen chest muscles, replace antibiotics, or diagnose CF—its primary role is to enhance airway clearance and help prevent infections.
