A biomedical signals monitoring system with multiple physiological signs measurement capability in real time is designed and implemented. This system performs a local vital sign data analysis using cell phone over wireless sensor network (WSN) technology and code division multiple access (CDMA) network. Cell phone-based personal medical recorder becomes popular to facilitate self-control of chronic diseases and observe patients' condition continuously. The risk of ignoring monitoring patients' physiological data by doctor is concerned since large quantities of data are processed and analyzed daily. An intelligent decision support system is developed to enhance healthcare providers' review of monitoring data.
