متن کاملLast Word on Point:Counterpoint: The major limitation to exercise performance in COPD is 1) inadequate energy supply to the respiratory and locomotor muscles, 2) lower limb muscle dysfunction, 3) dynamic hyperinflation.
TO THE EDITOR: The clear and resounding conclusion of the correspondents who weighed in on this debate is that exercise limitation in COPD is multifactorial. Protagonists who advance a single dominant mechanism of activity limitation in this phenotypically heterogeneous population do so at their peril. My esteemed colleagues, Drs. Maltais/Debigaré and Macklem/Aliverti must accept (however grudg...
متن کاملLung hyperinflation in COPD: applying physiology to clinical practice
In chronic obstructive pulmonary disease (COPD), worsening expiratory flow limitation together with alteration in the elastic properties of the lung are associated with progressive lung hyperinflation and gradual decline in the resting inspiratory capacity over time. Dynamic hyperinflation (DH) refers to the variable increase in end-expiratory lung volume (EELV) above the relaxation volume (VR)...
متن کاملCOPD: Journal of Chronic Obstructive Pulmonary Disease
Lung hyperinflation commonly accompanies expiratory flow-limitation in patients with Chronic Obstructive Pulmonary Disease (COPD) and contributes importantly to dyspnea and activity limitation. It is not surprising, therefore, that lung hyperinflation has become an important therapeutic target in symptomatic COPD patients. There is increasing evidence that acute dynamic increases in lung hyperi...
متن کاملPathogenesis of hyperinflation in chronic obstructive pulmonary disease
Chronic obstructive pulmonary disease (COPD) is a preventable and treatable lung disease characterized by airflow limitation that is not fully reversible. In a significant proportion of patients with COPD, reduced lung elastic recoil combined with expiratory flow limitation leads to lung hyperinflation during the course of the disease. Development of hyperinflation during the course of COPD is ...
متن کاملAdditive efficacy of short-acting bronchodilators on dynamic hyperinflation and exercise tolerance in stable COPD patients treated with long-acting bronchodilators.
The purpose of this study was to clarify the additive efficacy of short-acting β(2)-agonists (SABA) or muscarinic antagonists (SAMA) on dynamic hyperinflation and exercise tolerance in patients with chronic obstructive pulmonary disease (COPD) who had been treated with long-acting bronchodilators. Thirty-two patients with stable COPD who had been treated with long-acting bronchodilators, includ...
