Note the reduced FEV1/FVC and FEV1 (red circles) and the scooped curve shape of the dotted green expiratory flow loop (arrow, above X-axis), consistent with an obstructive defect. The airflow obstruction is reversible.
After treatment with a bronchodilator, there is significant improvement (>10%) in FEV1, and the FEV1/FVC ratio also increases (orange boxes). The expiratory flow volume loop (above X-axis) shown in solid blue is now nearly normal.آیا می خواهید مدیلیب را به صفحه اصلی خود اضافه کنید؟
