FPGA BASED BLOOD PRESSURE MONITORING SYSTEM by Fariha Naaz
Abstract
As Blood pressure is known to be the major indicator of a person’s health, thus there is an emerging demand for easy to use Continous Non invasive Blood Pressure monitoring (CNBP) systems. This paper describes the development of a System-on-a-chip (SOC) based wearable system for the measurement of Blood Pressure that will act as Continuous Noninvasive Blood Pressure (CNBP) system enabling the doctor to clearly analyze a patient’s blood pressure changes throughout the day. It
will replace bulky BP monitoring machine by merely a cuff as the developed SoC based system can be sewed up in the cuff itself, while the readings will appear on patient’s SMART phone. It will revolutionize the way BP was measured. The complete system will always ON, always working, so it
helps for Continuous BP monitoring where in a timer will be set in the Android Application for the BP measurement interval , these readings will be recorded in a table and can be analysed graphically for further decision making at the doctor’s end and also it will provide numerous possibilities for health benefits. A fully functional FPGA implemenntation for developing an SOC for Blood Pressure
monitoring has been succesfully implemented on Spartan3E kit using Xilinx ISE 12.4 with only 150 slices and 280 4-input LUTSs . SOC implementation will guarantee size minimization and also low power consumption suitable for battery operated device. The proposed design when compared with other commercial available digital BP Monitoring device, gave satisfactory readings. The future of Blood pressure measurement would just like operating a mobile Application
