Wearable Noninvasive Positive Pressure Ventilation Device in COPD
- Conditions
- Non-Invasive Ventilation
- Interventions
- Device: Non-Invasive Ventilation
- Registration Number
- NCT03130361
- Lead Sponsor
- Icadom
- Brief Summary
The objective is to assess the impact of a wearable Noninvasive Positive Pressure Ventilation, on physical activity and quality of life in patients with severe COPD, complaining of dyspnea.
- Detailed Description
In order to avoid the occurrence of uncomfortable dyspnea, patients with Chronic Obstructive Pulmonary Disease (COPD) are locked in a vicious circle of inactivity and social isolation which profoundly affects their quality of life and prognosis. A new wearable non invasive positive pressure ventilation device has been recently proposed; it can be used by intermittence during or after physical activities for reducing dyspnea or for shortening dyspnea- recovery time. The investigators hypothesize that this system, in reducing the inconvenience caused by dyspnea, would stimulate a more active lifestyle and improve quality of life. Their objective is to assess the impact of this device on physical activity and quality of life in patients with severe COPD, complaining of dyspnea.
In this open study with no control group, participants will use the device at their convenience, according to their needs in daily life and for 4 weeks.

Group Intervention Description Noninvasive ventilation Non-Invasive Ventilation Participants will use the device at home by intermittence during or after physical activities for reducing dyspnea or for shortening dyspnea-recovery time over a 4-week period.
- Primary Outcome Measures
Name Time Method Change of daily physical activity measured by actimetry Continuously over a 8-week period (2 weeks before the use of the device, over the 4-week period usinf the device and 2 weeks after the use of the device Change of number of steps by day and daily energy expenditure over the 8 week period
- Secondary Outcome Measures
Name Time Method Change of Transition Dyspnea Index (TDI) baseline and post use of the Vitabreath device at 4th weeks The TDI assesses change of dyspnea perception from the BDI in each dimensions. Patient will rate score from -6 to +6 (positive score reflect improve of dyspnea and negative score reflect worse dyspnea).
Change of Chronic Obstructive Pulmonary Disease Assessment Test (CAT)score Continuously over a 8-week period (2 weeks before the use of the device, over the 4-week period usinf the device and 2 weeks after the use of the device The CAT represents health related quality of life of COPD patients
Subjective appréciation of the device post use of the Vitabreath device at 4th weeks Patients will rate their appreciation of the device using 3 scale relatives to ease of use, helps recovery shortness of breath, helps to be more active in daily life
Change of Modified Medical Research Council Questionnaire (mMRC) score baseline and post use of the Vitabreath device at 4th weeks The mMRC is one of dyspnea parameters
Change of Baseline Dyspnea Index (BDI) score baseline and post use of the Vitabreath device at 4th weeks The BDI represents importance and impact of dyspnea in daily life of COPD patients. The BDI is one of dyspnea parameters (questionnaire). Three dimension questions include; 1.effect of daily function on dyspnea, 2. effect of magnitude of task on dyspnea and 3. effect of magnitude off effort on dyspnea.
Change of Visual Simplified Respiratory Questionnaire (VSRQ) score baseline and post use of the Vitabreath device at 4th weeks The VRSQ represents health related quality of life of COPD patients
