第一秒用力呼气量占用力肺活量的百分率(FEV1 %)。
First second forced expiratory volume accounts for the percentage of FVC (FEV1%).
在所有三个组，血y KL - 40水平与哮喘严重程度正相关，而与一秒用力呼气量负相关。
In all three cohorts, serum YKL-40 levels correlated positively with the severity of asthma and inversely with the forced expiratory volume in 1 second.
方法：受试的对象为可疑的运动诱导的支气管痉挛的健康、体格健壮的个体，用乙酰胆碱激发气道反应后，测定一秒钟用力呼气量。
Methods: Healthy, athletic subjects who are suspected of having exercise-induced bronchospasm were recruited, and FEV1 values were determined following provocative airway challenges with methacholine.
