摘要
目的初步探讨脉冲振荡法在测定单纯打鼾及阻塞性睡眠呼吸暂停综合症(OSAS)呼吸阻抗中的诊断价值。方法应用脉冲振荡法(IOS)和流量-容积曲线检测19例健康人、11例单纯打鼾而无睡眠呼吸暂停综合症患者及21例打鼾而且伴有阻塞性睡眠呼吸暂停综合症患者。结果在粘性阻力(R35)方面,从健康组→单纯打鼾组→OSAS组阻力逐步增高,3组之间两两比较差异均存在显著性(P<0.05或P<0.01);阻抗容积图分析表明单纯打鼾组存在毛刺状图形的比率为27.27%,而OSAS组的比率为61.90%,两者比较差异存在显著性(P<0.01)。流量-容积曲线图形分析表明单纯打鼾组呼气及吸气曲线存在锯齿波的比率为18.18%,而OSAS组的比率为52.38%,两者比较差异存在显著性(P<0.01)。结论脉冲振荡系统可以作为单纯打鼾及阻塞性睡眠呼吸暂停综合症初筛的客观指标之一。
[Objective] To study the diagnostic value of using impulse oscillation （IOS） to measure the respiratory resistance in snore and OSAS. [Methods] Maximal expiratory flow-volume curve function testing and IOS testing were completed including 21 OSAS patients and 11 Snore patients without OSAS and 19 health humans. [Results] Resistant values at 35 Hz were gradually increased from health group to snore group and OSAS group. There were significantly differences in three groups （P 〈0.05 or P 〈0.01）. At impedance volumes map, flocky map rate was 61.90% in OSAS group and 27.27% in snore group （P 〈0.01）. At flow-volume curve, serration map rate was 52.38% in OSAS group and 18.18% in snore group （P 〈0.01）. [Conclusions] IOS may be regarded as one of routine measures filtrating pute snore and obstructive sleep apnea syndrome （OSAS）.
