Evaluation of the Effectiveness of the Nebulization Bronchodilators Under High Nasal Flow Humidified

Not Applicable

Completed

• Conditions: Chronic Obstructive Pulmonary Disease

• Registration Number: NCT02812979
• Lead Sponsor: University Hospital, Tours

Brief Summary

The principal objective is to show noninferiority of nebulized salbutamol through the high flow nasal system moistened AIRVO ™ 2 in terms of reversibility of airflow obstruction compared to nebulization by the usual method (spray mask).

Detailed Description

Randomized, comparative, non inferiority study between two nebulization strategies bronchodilators, one according to the method tested namely the spray - in across the top humidified nasal flow system and the other according to a customary procedure, through a mask. A third arm will be evaluated (control arm) to overcome a possible own bronchodilator effect of high flow nasal humidified.
