Effect of Noninvasive Ventilation on Physical Activity and Inflammation in COPD Patients

Overview

Parallel, randomized and controlled clinical trial to evaluate the effect of 12 months of noninvasive mechanical ventilation versus conventional treatment in hypercapnic patients with stable COPD. Main objective: To evaluate the effect of 12 months of noninvasive ventilation on c-reactive protein concentration and daily physical activity in hypercapnic patients with stable COPD. Secondary objectives: To compare the plasmatic concentration of other inflammatory biomarkers between COPD patients with conventional treatment and wich noninvasive ventilation. To determine the response of breathlessness, health-related quality of life and lung function to noninvasive ventilation. To identify the COPD patients with a higher gasometric and clinic response to noninvasive ventilation.
