No room to breathe: the importance of lung hyperinflation in COPD.
Patients with chronic obstructive pulmonary disease (COPD) are progressively limited in their ability to undertake normal everyday activities by a combination of exertional dyspnoea and peripheral muscle weakness. COPD is characterised by expiratory flow limitation, resulting in air trapping and lung hyperinflation. Hyperinflation increases acutely under conditions such as exercise or exacerbat...
متن کاملLUNG HYPERINFLATION IN COPD: What the Clinician Needs to Know
Lung hyperinflation, chronic dyspnea and reduced exercise capacity are inextricably linked and are independent predictors of increased mortality in COPD. It is no surprise, therefore, that a major goal of management is to reduce lung hyperinflation in the hope of improving dyspnea, exercise tolerance and related long term patientcentered outcomes. The negative effects of lung hyperinflation on ...
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 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 کاملLung hyperinflation in COPD: the impact of pharmacotherapy
Improvement in airway function in response to bronchodilator therapy is generally confirmed by simple spirometry. However, improvements in maximal expiratory flow rates have been shown to correlate poorly with important patient-centred outcomes, such as reduced exertional dyspnoea and improved exercise performance. Recent studies have suggested that attendant reductions in end-expiratory lung v...
