摘　　要：目的评价脉搏传导时间(PTT)对睡眠呼吸暂停和微觉醒的诊断价值。方法30例有打鼾史拟行睡眠监测患者,同步应用PTT睡眠监测仪和多导睡眠监测仪(PSG)进行整夜睡眠监测,对所记录呼吸事件和微觉醒指数进行比较。结果对24例完整的有效数据进行比较,PTT监测所得AH I、睡眠呼吸事件、微觉醒指数与PSG结果无显著差异(P>0.05)。结论作为诊断睡眠呼吸暂停低通气综合征的简易监测设备,PTT睡眠监测仪可有效判定睡眠呼吸事件和微觉醒。Objective To study the value of pulse transit time （PTT） on the diagnosis of sleep respiratory events and microarousals. Methods Overnight PTT was recorded in 30 patients being investigated for OSAHS ,with full polysomnography（PSG） at the same time in the sleep laboratory. AHI,sleep respiratory events and microarousal index obtained from PTT were compared with those from PSG. Results Among 24 cases with available data, no significant difference of AHI, sleep respiratory events and microarousal index,etc, was found between PTT and PSG （ P 〉 0.05 ）. Conclusion Pulse transit time can provide a valid estimate of respiratory events and a measure of arousals and be useful on the diagnosis of obstructive sleep apnea hypopnea syndrome.
