CPAP decreases lung hyperinflation in patients with stable COPD.
BACKGROUND Dynamic hyperinflation, caused by expiratory flow limitation, markedly increases resting end-expiratory lung volume (functional residual capacity) in many COPD patients. OBJECTIVE To determine the impact and duration of impact of CPAP on hyperinflation and airway resistance in patients with stable COPD. METHODS In a case series, 21 patients underwent CPAP at 8 cm H(2)O for 15 min...
متن کاملLongitudinal changes in lung hyperinflation in COPD
PURPOSE COPD is characterized by an accelerated and progressive decline in forced expiratory volume in 1 second (FEV1) and lung hyperinflation. Although lung hyperinflation is the hallmark of COPD, data on the longitudinal changes in lung hyperinflation and any association with the decline in FEV1 are lacking. The aim of this study was to evaluate the longitudinal changes in lung hyperinflation...
متن کاملExercise training decreases ventilatory requirements and exercise-induced hyperinflation at submaximal intensities in patients with COPD.
STUDY OBJECTIVES We hypothesized that endurance exercise training would reduce the degree of hyperinflation for a given level of exercise and thereby improve submaximal exercise endurance. METHODS Twenty-four patients with COPD (mean FEV(1), 36.4 +/- 8.5% of predicted [+/- SD]) undertook a high-intensity cycle ergometer exercise training program for 45 min, three times a week for 7 weeks. Bef...
متن کاملEarly COPD patients with lung hyperinflation associated with poorer lung function but better bronchodilator responsiveness
BACKGROUND It is unknown whether aggressive medication strategies should be used for early COPD with or without lung hyperinflation. We aimed to explore the characteristics and bronchodilator responsiveness of early COPD patients (stages I and II) with/without lung hyperinflation. METHODS Four hundred and six patients with COPD who performed both lung volume and bronchodilation tests were ret...
متن کاملEffects of noninvasive ventilation on lung hyperinflation in stable hypercapnic COPD.
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 ...
