In addition, red tide exposure was associated with significant reductions in FEV1, midexpiratory phase of forced expiratory flow, and peak expiratory flow. 另外,暴露于红潮会引起FEV1&强迫呼气流量中值和呼气气流峰值减少。
FEF ( Forced Expiratory Flow(FEF) Rate ) was measured in 92 smokers without respiratory symptom and 78 healthy non-smokers. 本文对92例无症状吸烟者及78例不吸烟健康人进行最大呼气流速的测定。
New Parameters for Pulmonary Function Testing Accelerations of Forced Expiratory Flow(FEF) 肺功能测试的新参数:用力呼气流量之加速度
This study also analyses the relationship between frequency dependence of Rth and parameters of the forced expiratory vital capacity curve and of the maximal expiratory flow volume curve. 本文还分析其与用力呼气肺活量曲线及最大呼气流量&容积曲线有关指标的关系。
After therapy the forced expiratory volume in one second ( FEV 1 0, FEV 1 0 % ), peak expiratory flow rate ( PEF ), and forced vital capactity ( FVC ) were obviously improved and in CAG the improvements of pulmonary functions were much more significant. 治疗后1秒钟用力呼气容积(FEV1.0及FEV1.0%)、最大呼气峰流速(PEF)和用力肺活量(FVC)均有明显改善,以寒哮组肺功能改善差异性更为显著。
