CHRONIC OBSTRUCTIVE PULMONARY DISEASE Bronchodilator reversibility testing in chronic obstructive pulmonary disease
Background: A limited or absent bronchodilator response is used to classify chronic obstructive pulmonary disease (COPD) and can determine the treatment offered. The reliability of the recommended response criteria and their relationship to disease progression has not been established. Methods: 660 patients meeting European Respiratory Society (ERS) diagnostic criteria for irreversible COPD wer...
متن کاملBronchodilator 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...
متن کاملOverlap Syndrome in Respiratory Medicine: Asthma and Chronic Obstructive Pulmonary Disease
Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent chronic diseases in the general population. Both are characterized by similar mechanisms: airway inflammation, airway obstruction, and airway hyperresponsiveness. However, the distinction between the two obstructive diseases is not always clear. Multiple epidemiological studies demonstrate that in elderly people with o...
متن کاملBronchodilator response in patients with normal baseline spirometry.
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 bronchodilator response, as defined by American Thoracic Society/European Respiratory Society criteria, has not been described. METHODS We retrospectively analyzed adult patients tested in 2 academic pulmonary ...
متن کاملShort term variability in FEV1 and bronchodilator responsiveness in patients with obstructive ventilatory defects.
Short term variability in FEV1 and responsiveness to inhaled bronchodilator were measured in 150 patients with obstructive ventilatory defects. The range of initial FEV1 was 0.5-4.71 and the natural variability over a 20 minute period when expressed in absolute terms was similar over the entire range, and differed insignificantly from that found in normal subjects. The increase in FEV1 and vita...
