Wearable Noninvasive Positive Pressure Ventilation Device in COPD

Not Applicable
Completed
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.

Noninvasive ventilationNon-Invasive VentilationParticipants 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
NameTimeMethod
Change of daily physical activity measured by actimetryContinuously 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
NameTimeMethod
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)scoreContinuously 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 devicepost 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) scorebaseline and post use of the Vitabreath device at 4th weeks

The mMRC is one of dyspnea parameters

Change of Baseline Dyspnea Index (BDI) scorebaseline 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) scorebaseline and post use of the Vitabreath device at 4th weeks

The VRSQ represents health related quality of life of COPD patients
