Remote Blood Pressure Monitoring Using a Wireless Sensor Network

Abstract

A system to remotely monitor a patients blood pressure (BP) is described. The data is transferred to a central monitoring station using a wireless sensor network for display and storage. Crossbow MICAz motes were programmed to serve as the network nodes. One mote was interfaced to the BP monitor for data acquisition and the others were utilized to route the BP data to the monitoring station. A user-friendly graphical user interface was designed for monitoring current and past measurements for all patients being monitored. Test results indicated high accuracy in BP measurements. Power consumption by the BP monitor interfaced mote was minimized by forcing it into a low power sleep mode when not in use.
