Conclusion
A prototype BP monitoring system using WSNs has been designed and developed.
The system allows health personnel to monitor a patient's BP from a remote
location without requiring the physician to be physically present to take the
measurements. The system concept can be used for routing vital sign information
to a central location within the hospital premises as well as in applications that
require monitoring from within a patient's home.
Utilizing a sensor node tied to the BPM, we have successfully initiated a
reading, gathered the data, and can forward it through the network to the base
station. The measurements are then forwarded through the serial port to the host
computer and the GUI displays the data correctly. Multiple sensor nodes are
programmed to represent multiple patients. The patients have their own unique
sensor node IDs whose measurements were successfully transmitted to the base
station and then forwarded to the GUI for display
The BP measurements of patients were fairly accurate and equaled the mea-
surements displayed on the monitor LCD display. Further research will focus
toward integrating smaller OEM medical sensor boards to the Crossbow sensor
nodes to miniaturize their size and make the system more practical.
