Abstract |
BACKGROUND In the measurement of bronchodilator reversibility, the forced expiratory volume in one second(FEV(1)) and the forced vital capacity(FVC) are commonly used parameters and recommended criteria for the reversibility requiring an increase of more than 200ml and 12% above the baseline, respectively. However, aged patients do not often meet the criteria of an increase in volume(>200ml) even though the medical history of that patient is adequate for asthma. This study investigated the role of the forced expiratory volume in six seconds(FEV(6)) in the bronchodilator reversibility test in elderly patients. METHODS: A total of 236 patients more than 65 years of age with a FEV(1)/FVC ratio<80% were enrolled in this study. The bronchodilator revesibility tests were examined. With the setting FEV(1) as the baseline, the patients were divided into three groups; Group I: FEV(1)> or = 80% of the predicted value, Group II: 60%
