探讨加用气流阻力负荷（ＦＲＬ） 状态下流速容量（ＦＶ） 曲线检查对初检ＯＳＡ 患者的意义对象为２４ 名健康成年男性及２１ 例男性阻塞性睡眠呼吸暂停（ＯＳＡ） 患者经整夜多导睡眠仪检查诊断或排除ＯＳＡ模拟实验结果发现只有同时加上可陷闭管及ＦＲＬ 时，才出现显著吸气气流受限无ＦＲＬ时，ＦＶ 曲线（ 以ＦＥＦ５０／ＦＩＦ５０ 比值大于１ 为指标） 检查发现ＯＳＡ的敏感性和特异性分别为３３ ．３ ％ 和９１ ．６ ％ ，阳性预测率为６３ ．６ ％ 加用ＦＲＬ 时敏感性为７６ ．２ ％ ，特异性为７５ ％ ，阳性预测率为７２ ．２ ％ 吸、呼气相峰值流速比值及中期峰值流速比值与ＯＳＡ 严重呈显著相关联合应用加ＦＲＬ及常规ＦＬ曲线检查可能对ＯＳＡ 患者初筛有较高价值 To investigate the significance of flow-volume (FV) curve examination in patients with newly diagnosed OSA under the condition of FRL.  The subjects were 24 healthy adult men and 21 men with obstructive sleep apnea (OSA) After overnight polysomnography to diagnose or exclude OSA simulation results showed that only with the tracheal tube and FRL can be added at the same time, there was no significant limitation of inspiratory flow FRL without FRL (FEF50 / FIF50 ratio greater than 1 for the index) examination found OSA sensitivity and specificity were 33. 3% and 91. 6%, positive predictive rate of 63. 6%  with the FRL sensitivity of 76. 2%, specificity of 75%, positive predictive value of 72. 2%  absorption, peak expiratory flow rate ratio and the mid-peak flow rate ratio was significantly correlated with severe OSA  combined application of FRL and routine F-L curve screening may have higher value of OSA screening
