Bronchodilator reversibility in patients with COPD revisited: short-term reproducibility

Categorization of patients with COPD as reversible or nonreversible to a bronchodilator may change over time. This post hoc analysis aimed to determine if an individual's reversibility, when treated as a continuous variable, could predict his/her future response to two short-acting bronchodilators: albuterol and ipratropium. The analysis was completed using data from a 4-week, randomized, open-...

Bronchodilator reversibility testing: laboratory practices in Australia and New Zealand.

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 Zealand. DESIGN A postal survey performed in 2000, requesting details of methods used to assess and interpret bronchodilator reversibility. SETTING AND PARTICIPANTS 60 lung-function laboratories identified from t...
