Wireless Telemedicine Physiological Monitoring Center Based on Virtual Instruments

This paper presents a new model of wireless telemedicine physiological monitoring center, which is developed by the Laboratory Virtual Instrument Engineering Workbench (LabVIEW) and integrates current general packet radio service (GPRS) technology and signal processing with DSP processor. At the patient´s location, a wireless PDA-based monitor is used to continuously acquire the patient´s vital signs, including heart rate, ECG, SpO₂ and so on. Through the internet, the patient´s physiological signals can be transmitted in real-time to a telemedicine monitoring central management unit, and the unit can access the data and the case history of the patient, either by the central management unit or the wireless devices. This paper presents our prototype implementation of signal processing based on a high-performance DSP-based personal server. The results also show that the wireless telemedicine physiological monitoring center model is superior to the currently used monitors both in mobility and in usability, and, therefore, is better suited to patient transport.
