Hypertension and cardiac arrest detection using silver electrodes and heart sensor on FPGA platform.

Abstract

Hypertension is the condition in which the force of the blood against the artery walls is too high. Cardiac arrest is an unexpected loss of heart system working, breathing and anything related to heart. Both these states are measured by the device called Mercury Sphygmomanometer. Mercury sphygmomanometers are considered the gold standard. They show blood pressure by change in height of mercury. But there is a discontinuation in mercury sphygmomanometer due to its bulky size, inaccurate gauge and underperformed on hearing and visually impaired people. This paper studies a hypothesis to investigate the possibility of obtaining simultaneous accurate blood pressure measurements which can parallelly cause cardiac arrest and skin response through the pulses to detect the tension rate using FPGA. In this paper we will be studying XILINX SPARTAN 3 XCS 400(4MHZ) FPGA. The analog value from the GSR (Galvanic Skin Response) and Heart Rate Sensor is converted into digital value using analog to digital converter. The digital value is further processed by the FPGA to check the GSR and Heart Rate Sensor and give the alert. If the value is crossed through certain threshold limit then the alert is displayed into 16*2 LCD.
