Sleep apnea preliminary screening method and system based on BCG signal

The invention discloses a sleep apnea preliminary screening method and system based on a BCG signal. The sleep apnea preliminary screening method and system are used for conducting long-term monitoring and risk early warning on patients with apnea disorder and people with potential apnea disorder. According to the method, a BCG signal of a monitored person is obtained in a non-invasive and non-contact mode, and an apnea event is detected in combination with pseudo-periodic body movement characterization generated in sleep of an apnea patient and respiratory effort characteristics; the system mainly comprises a BCG signal acquisition module, a BCG signal preprocessing module, an apnea feature recognition module and an apnea event output module. The system can automatically and accurately analyze the severity of the sleep breathing disorder of the monitored person in the sleep process. 本发明公开了一种基于BCG信号的睡眠呼吸暂停初筛方法以及系统，用以对有呼吸暂停障碍的患者以及存在潜在呼吸暂停障碍人群进行长期监测以及风险预警；该方法通过无创非接触的方式获取监测人员的BCG信号，结合呼吸暂停患者在睡眠中的产生的伪周期体动表征以及呼吸努力的
