Wearable Noninvasive Positive Pressure Ventilation Device in COPD (VITABREATH)
Evaluation of the Impact of a Wearable Noninvasive Positive Pressure Ventilation Device on Physical Activity and Quality of Life in Patients With COPD
調査の概要
詳細な説明
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.

メジャーの説明 |
時間枠 |
|---|---|---|

Change of Baseline Dyspnea Index (BDI) score
時間枠: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 Modified Medical Research Council Questionnaire (mMRC) score
時間枠:baseline and post use of the Vitabreath device at 4th weeks
|
The mMRC is one of dyspnea parameters
|
baseline and post use of the Vitabreath device at 4th weeks
|
|
Change of Transition Dyspnea Index (TDI)
時間枠: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).
|
baseline and post use of the Vitabreath device at 4th weeks
|
|
Subjective appréciation of the device
時間枠: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
|
post use of the Vitabreath device at 4th weeks
