    Effects of noninvasive ventilation on lung hyperinflation in stable hypercapnic COPD
    (EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2002) Diaz, O; Begin, P; Torrealba, B; Jover, E; Lisboa, C
    Two previous uncontrolled studies have suggested that noninvasive mechanical ventilation (NIMV) in patients with hypercapnic chronic obstructive pulmonary disease (COPD) improves arterial blood gas tensions by decreasing lung hyperinflation with the consequent reduction in inspiratory loads and changes in ventilatory pattern. The aim of this randomised placebo-controlled study was to determine whether these mechanisms play a pivotal role in the effects of NIMV on arterial blood gases.

    Physiological and clinical effects of diurnal noninvasive ventilation in hypercapnic COPD
    (EUROPEAN RESPIRATORY SOC JOURNALS LTD, 2005) Diaz, O; Begin, P; Andresen, M; Prieto, ME; Castillo, C; Jorquera Arévalo, Jorge Antonio; Lisboa, C
    To assess the clinical impact of noninvasive mechanical ventilation (NIMV) on stable hypercapnic chronic obstructive pulmonary disease, changes in exercise capacity, dyspnoea and simple physiological parameters were evaluated. The time course of these effects during treatment and recovery was also assessed.
