Objectives: To determine the variation in the methods used to assess and interpret the
reversibility of airflow limitation in lung‐function laboratories throughout Australia and New …

The history of the bronchodilator test dates back to the late 1950s when airway diseases
were classified as reversible or irreversible depending on the response to bronchodilators …

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

Normative cut-off values for the bronchodilator reversibility test are published neglecting
factors that may influence the test result other than disease. The objective of this cross …

BACKGROUND: Spirometry before and after bronchodilator is performed to assess air flow-
limitation reversibility. In patients with normal baseline spirometry the frequency of a positive …

Objective Because published criteria for bronchodilator responsiveness are based on
population variability and compare only the single best measures before and after …

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

Airway reversibility test (or bronchodilatation test) is performed routinely in the diagnosis of
obstructive lung diseases. The results of this test may be helpful in the diagnosis and …

ilation of spirometry, IOS and body plethysmography in patients with COPD. They found that,
although spirometry is more reproducible than IOS and body plethysmography, total …

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