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

Background COPD is defined as partly irreversible airflow obstruction. The response pattern
of bronchodilators has not been followed in advanced lung function parameters. Purpose …

Background: A limited or absent bronchodilator response is used to classify chronic
obstructive pulmonary disease (COPD) and can determine the treatment offered. The …

COPD is a preventable and treatable disease characterized by airflow limitation that is not
fully reversible. The diagnosis of COPD is based on spirometric evidence of airways …

BACKGROUND: The Global Initiative for Chronic Obstructive Lung Disease (GOLD)
recommends the use of forced expiratory volume in 1s (FEV1) to assess airways …

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 …

Partial bronchodilator reversibility can be demonstrated in many patients with stable chronic
obstructive pulmonary disease (COPD), but its relevance to exercise capacity and symptoms …

Background and aims: Bronchodilator reversibility (BDR) and inhaled corticosteroid (ICS)
use were assessed for volunteers who responded to an advertisement requesting current or …

The change in forced expiratory volume in 1 s (FEV 1) after administration of a short-acting
bronchodilator has been widely used to identify patients with chronic obstructive pulmonary …
