Abstract:
Objective The purpose of this study was to determine the efficacy of forced expiratory volume in six seconds(FEV6) as an alternative for forced vital capacity(FVC)and the fixed eat-off points for FEV1/FEV6 in the diagnostic screening for chronic obstructive pulmonary disease (COPD).Methods From August 2007 to December 2008,a total of 1210 spirometric examinations in were analyzed,FEV6 was measured on volume-time curves.The correlation between FEV1/FVC and FEV1/FEV6 was evaluated by the Kendall correlation test.Considering FEV1/FVC
