Abstract

A generic, realtime wireless telemedicine system has been developed that uses the Bluetooth protocol and the general packet radio service for mobile phones. The system was tested on 10 healthy volunteers, by continuous monitoring of their electrocardiograms (ECGs). Under realistic conditions, the system had 96.5% uptime, a data throughput of 3.3 kbit/s, a mean packet error rate of 8.5x10(-3) packet/s and a mean packet loss rate of 8.2x10(-3) packet/s. During 24 h testing, the total average downtime was 66 min and 90% of the periods of downtime were of only 1-3 min duration. Less than 10% of the ECGs were of unacceptable quality. Thus, the generic telemedicine system showed high reliability and performance, and the design may provide a foundation for realtime monitoring in clinical practice, for example in cardiology.

摘要

已开发出一种通用的实时无线远程医疗系统，该系统使用蓝牙协议和面向手机的通用分组无线服务。通过对10名健康志愿者的心电图（ECG）进行连续监测，对该系统进行了测试。在实际条件下，该系统的正常运行时间为96.5%，数据吞吐量为3.3 kbit/s，平均分组错误率为8.5×10⁻³个分组/秒，平均分组丢失率为8.2×10⁻³个分组/秒。在24小时测试期间，总平均停机时间为66分钟，90%的停机时间段仅持续1至3分钟。质量不可接受的心电图不到10%。因此，该通用远程医疗系统显示出高可靠性和性能，其设计可为临床实践中的实时监测（例如在心脏病学中）提供基础。
