An embedded medical advisory system for mobile cardiovascular monitoring devices

The traditional sphygmomanometers only monitor the blood pressure and heart rate, which are generally too simple to reflect the health condition of cardiovascular system. Recently, the advance of hemodynamic analysis of sphygmogram promotes the novel cardiovascular monitoring devices. These devices generally can extract more than 20 vital signs from sphygmogram. However, since most of the vital signs are too professional for home users, it is essential to well design the accompanied medical advisory system for easy acceptance in home healthcare. Here a hierarchical medical advisory system is proposed to generate exception alarming messages and provide comprehensive health assessment as well as intelligent medical diagnosis. Due to the self-adaptive medical knowledge base, this embedded system is able to provide the considerable medical services while adaptive to the resource-limited mobile platform. The cardiovascular monitoring device has been successfully implemented in an ARM-based mobile platform.
