摘　　要：睡眠质量对人的健康至关重要,为减小多导睡眠图仪监测睡眠时给患者带来的生理心理负荷,采用了一种仅通过监测双光源手指脉搏信号来完成患者睡眠质量监测的方法。通过硬件电路采集整夜的双光源手指脉搏波信号,再用上位机软件对信号进行分析,从中分离出睡眠相关信息,从而对睡眠质量进行客观评估。该方法对睡眠几乎没有影响,记录方法简单、操作方便、成本低,可以较好地判断睡眠质量,适用于对患者长时间的睡眠监测。Sleep quality is an essential factor for human health,in order to avoid the unwanted physiological and psychological stress of patients caused by overnight polysomnography, a new method based on pulse wave signal with monitoring dual light sources is adopted to monitor the sleeping of patients. The hardware is used for overnight pulse wave signal acquisition. The upper computer software is used to analyze the signal, relevant information of sleep and evaluate sleep quality are extracted. This method nearly has no effect on sleep as well as maintains advantages of brief recording process ,convenient operation and low cost. It can evaluate sleep quality better and be suitable for patient to do a long-term sleep monitoring.
