A wireless portable monitoring system for respiratory diseases using microsensors is proposed. The monitoring system consists of two sensor nodes integrating with Bluetooth transmitters that measure user's respiratory airflow, blood oxygen saturation, and body posture. The utility of micro-hot-film flow sensor makes the monitor can acquire comprehensive respiration parameters which are useful for diagnoses of obstructive sleep apnea, chronic obstructive pulmonary disease, and asthma. The system can serve as both sleep recorder and spirometer. Additionally, a mobile phone or a PC connected to the Internet serving as a monitoring and transfer terminal makes telemedicine achievable. Several experiments were conducted to verify the feasibility and effectiveness of the proposed system for monitoring and diagnosing OSA, COPD, and asthma.
提出了一种使用微传感器的无线便携式呼吸疾病监测系统。该监测系统由两个集成蓝牙发射器的传感器节点组成，可测量用户的呼吸气流、血氧饱和度和身体姿势。微热线式流量传感器的实用性使得该监测器可以获取全面的呼吸参数，这对于诊断阻塞性睡眠呼吸暂停、慢性阻塞性肺疾病和哮喘非常有用。该系统可用作睡眠记录器和肺活量计。此外，连接到互联网的移动电话或 PC 可用作监测和传输终端，实现远程医疗。进行了几项实验以验证该系统用于监测和诊断 OSA、COPD 和哮喘的可行性和有效性。
