Using Post-bronchodilator FEV1 is Better Than Pre-bronchodilator FEV1 in Evaluation of COPD Severity

Abstract

The post-bronchodilator percent predicted FEV1 is better than the pre-bronchodilator percent predicted FEV₁ in the evaluation of the severity of disease in COPD patients and is more accurate in predicting the risk of death by the GOLD classification.
