Objective To study the value of pulse transit time(PTT) on the diagnosis of sleep respiratory events and microarousals.
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。
Objective Pulse transit time (PTT) is a non-invasive index which reflects changes in peripheral vascular resistance and intra-thoracic pressure.
目的PTT是一项反映周围血管阻力和胸腔内压变化的无创指标，因此和微觉醒相关的血压改变可通过PTT检测。
Experimentally, a light pulse propagating through the atomic vapor cell has its peak reaching the exit side before entering it, resulting in a negative transit time, and negative group velocity.
研究发现，当光脉冲通过一个原子气室时，在进入前其峰即到达出口处，造成负渡越时间和负群速。
