困倦是导致车祸的主要因素之一。许多汽车公司和机构一直在研究如何监测司机的睡意，让他们保持清醒。当在驾驶过程中检测到困倦时，通常会使用可听到的声音、振动或显示器上的信息来警告驾驶员集中精力驾驶或休息。这些方法在一定程度上有助于防止与嗜睡有关的撞车事故，但为了更大的安全性，需要开发从生理上克服嗜睡的方法。克服困倦的关键是保持身体不断地供应氧气。我们关注的是心肺相同步（CRPS）从困倦时的氧饱和度恢复。该研究发现，利用与心跳同步的脉搏声，有节奏地呼吸（PB）可以诱发CRPS。实验结果表明，在此过程中，前额测得的SpO2升高。SpO2的增加比打哈欠、深呼吸或一段时间的困倦自发减少时要大。综上所述，利用与心跳同步的脉冲声诱导CRPS在生理上具有减少嗜睡的潜力。
Drowsiness is one of the major factors leading to car accidents. Many automobile companies and institutions have been studying ways to monitor drowsiness and keep drivers awake. When drowsiness is detected during driving, audible sound, vibrations, or messages on a display are generally used to warn the driver to concentrate on driving or to take a rest. These methods help to prevent drowsiness-related crashes to some extent, but for greater safety, methods need to be developed to physiologically overcome drowsiness. The key to overcoming drowsiness is to keep the body constantly supplied with oxygen. We focused on cardiorespiratory phase synchronization (CRPS) to recover from oxygen desaturation during drowsiness. This study found it possible to induce CRPS by paced breathing (PB) using pulse sound, which synchronized with heartbeats. The experiment results showed SpO2 measured from forehead increased during this PB. The increase in SpO2 was larger than that of yawns, deep breathing, or a period of drowsiness spontaneously reduced. In conclusion, inducing CRPS by PB using pulse sound synchronized with the heartbeat has the potential to reduce drowsiness physiologically.
