Evaluation of a Mobile HFCWO Device in Cystic Fibrosis Patients

This clinical research study evaluates the effectiveness of a mobile high-frequency chest wall oscillation (HFCWO) device, the Monarch Airway Clearance System, in comparison to a standard HFCWO device, The Vest Airway Clearance System, for airway clearance in patients with cystic fibrosis (CF). The study employed a randomized, open-label crossover design, involving subjects aged 15 years and older who were stable on CF medications and had daily sputum production. Each subject underwent therapy with both devices after a washout period. The primary outcome measured was the mean wet weight of sputum collected during therapy, alongside Brody scores and functional respiratory imaging (FRI) assessments. Results indicated that while sputum production was comparable between the two devices, the Monarch System showed statistically significant improvements in lung status as measured by Brody scores and FRI parameters, suggesting enhanced mucus transport. The findings support the use of the Monarch System in CF management.
