Bronchodilator drugs produce variable improvements in forced expiratory volume in 1 s
(FEV1), but larger changes in end-expiratory lung volume (EELV) in chronic obstructive …

Background: A study was undertaken to investigate whether bronchodilators are associated
with less breathlessness at rest and during light exercise in patients with moderate to severe …

Dyspnoea provoked either by exercise or during a disease exacerbation is one of the most
feared symptoms of the chronic obstructive pulmonary disease (COPD) patient. It contributes …

We hypothesized that an altered effect of lung inflation on airway caliber may in part explain
the isolated volume response to bronchodilators, ie, an increase of forced vital capacity …

Bronchodilator therapy in COPD is deemed successful if it improves ventilatory mechanics to
a degree where effective symptom alleviation and increased exercise capacity are achieved …

Expiratory airway collapse is a characteristic feature in patients with chronic obstructive
pulmonary disease (COPD). We hypothesized that this collapse might mask the effects of …

Background: Although airflow limitation improved by inhaled anticholinergic drugs varies
among individuals with chronic obstructive pulmonary disease (COPD), the relationship …

BACKGROUND: Chronic obstructive pulmonary disease (COPD) patients are thought to
have limited bronchodilator response, determined by changes in forced expiratory volume in …

BACKGROUND Bronchodilator reversibility testing is recommended in all patients with
chronic obstructive pulmonary disease (COPD) but does not predict improvements in …

Background: Patients with chronic obstructive pulmonary disease (COPD) show different
spirometric response patterns to bronchodilator, such that some patients show improvement …
