The design of wearable sleep apnea monitoring wrist watch

摘要

This paper has presented a wearable sleep apnea monitoring wrist watch, its micro controller controls sensors to detect user's respiratory airflow, blood oxygen saturation(SpO₂), electrocardiogram(ECG) and breathing movement in real-time. Then our algorithm uses these physiological parameters to estimate whether the apnea occurs or not. In addition, this wrist watch provides motion state of users and some environmental parameters like temperature, humidity and atmospheric pressure. A liquid crystal display(LCD) module is used to show the parameters above. This wrist watch can send all the physiological parameters to the application on smartphone or computer by Bluetooth, where doctors can use these data for further analysis. Based on experimental test, the highly-integrated wrist watch can provide reliable measurement results. It avoids hospital's high cost and complicated procedures, and expands the screening scope of sleep apnea syndrome.
