Experimental: SIMEOX |
Other: Autogenic drainage
Manual aiway clearance by autogenic drainage |
Active Comparator: Autogenic Drainage |
Device: SIMEOX
Instrumental airway clearance by the medical device SIMEOX |
- Low frequency resistance R5 [ Time Frame: 1 month ]Comparison of variations V4 and V8 sessions (pre and post airway clearance session)
- Comparison of the impact of Simeox® bronchial drainage compared to autogenous drainage on respiratory symptoms: dyspnea, congestion and fatigue [ Time Frame: 1 month ]
- Evaluation of the distal and / or proximal decluttering by the two techniques, according to the improvement profile of the forced oscillations [ Time Frame: 1 month ]
- Evaluation of the impact of Simeox® bronchial drainage vs autogenous drainage by spirometry and plethysmography (distension and resistance) [ Time Frame: 1 month ]
- Evaluation of correlations between clinical benefit and changes in functional respiratory investigations (forced oscillations, spirometry, plethysmography) [ Time Frame: 1 month ]
