Home Airway Clearance in CF Patients (HomeCareSIMEOX)

Efficiency and Acceptability of SIMEOX® Used Autonomously at Home for Bronchial Clearance in Patients With Cystic Fibrosis: Prospective, Randomized Controlled Study

Regular bronchial clearance is essential in patients with cystic fibrosis for their bronchial health. SIMEOX® (Physio-Assist, Aix en Provence, France) is an innovative medical device for the drainage of the bronchial tree.

By changing the rheological properties of mucus, SIMEOX® helps to mobilize secretions and assists their transport to the upper airways. This technology is based on fundamental research on bronchial mucus rheology. At the present time, SIMEOX® device is mainly used over a short period at the time or after an exacerbation in healthcare structures (hospitals, physiotherapy practices, post-care, and rehabilitation units, etc…). The clinical effects observed in the short term encourages long-term autonomous use by the patients themselves.

The overall objective of this study is to evaluate the efficiency and acceptability of SIMEOX® used at home by the patient himself for bronchial clearance in patients with cystic fibrosis.
