近年来，睡眠呼吸障碍人群呈年轻化趋势。虽然人们对自身健康管理需求日益增长，但由于对慢性病长期积累效应严重性认识不足，且受到临床检测手段（PSG）费用高且需要专业医师指导等客观限制，睡眠呼吸障碍未能得到及时干预和管理。这越来越严重影响人们精神状态和生活质量，引发多种心脑血管疾病，威胁生命健康，导致交通事故频发，危害公众安全。因此，本项目拟设计高性价比的便携式睡眠呼吸音采集系统；提取呼吸音多元特征参数并进行统计优化；提出综合判别新指标以识别各种睡眠呼吸状态；以临床金指标PSG得到的低通气指数AHI为参照，确认新指标分析睡眠呼吸障碍的有效性及其与呼吸换气状态变化的关联性；最终应用正常、异常呼吸状态比例等参数，评价睡眠质量并研究其与精神状态的关系。本项目旨在为后续深入开展家庭个性化睡眠干预提供可靠的理论评价体系，为提升睡眠及精神健康认知度进行科普宣传，为实现社会大健康的发展目标助力。

In recent years, the incidence of sleep-related breathing disorders has been trending younger. Although the requirement of individual health management increases, the sleep-related breathing disorders can not get timely intervention limited by the lacking cognition of long-term accumulation effect of chronic diseases, the high cost and complex operation of clinical testing (polysomnography, PSG) and so on. So the sleep-related breathing disorders will effect the spirit condition and life quality of human being seriously. It will lead to kinds of cardiac-cerebral vascular diseases and the traffic accident, threatening people’s life and endangering public safety. Therefore, the project will design a portable sleep breathing sound acquisition system with higher cost performance. The multivariate features are extracted based on collected breathing sound signal and statistical optimization is applied to process the features. Then a new comprehensive identification index is proposed to identify various sleep breathing states. The efficiency of new index for analyzing sleep-related breathing disorders is confirmed by taking the apnea-hypopnea index (AHI) from PSG as an reference. The correlation between the new index and changes of breathing ventilation states is researched as well. Finally, the ratio of normal and abnormal breathing states and other parameters will be used to evaluate the sleep quality and spirit states. The project aims to provide a reliable theoretical evaluation system for developing the follow-up family personalized sleep intervention, popularize popular science knowledge to increase the awareness of sleep and mental health, and to promote the development of healthy society.
