Abstract:
This study aims to develop an automatic system for persistent collection of physiological information such as pulse rate and SpO2 in daily environment. The system includes a home-based user terminal and an Internet database server. The user terminal consists of a SpO2 sensor and a bedside box. The bedside box receives the physiological data from the sensor by Bluetooth connection and relays the data to an Internet-based database server. This system was used to collect the data during daily sleep from a female volunteer at her thirties for a period of more than 15 months. Superior persistence characteristic in daily data collection was confirmed and achieved up to 93.1% of data collection rate comparing with many allied devices or systems that usually ranged about 25% or even less. Average length of menstrual cycles in the female subject was estimated 24.9 days by the cosinor analysis method using the collected data. The result showed satisfactorily accurate with comparing self-record
ed length of 27.5±1.3 days. This system is expected to serve as a significant approach for long-term data collection and to obtain more reliable results for the purpose of tracking biorhythm and health condition change.
