Patient health monitoring system

Abstract

This is an experimental study for acquisition, measurement, processing and display of human health parameters like ECG, Body temperature as well as Saline status. Primarily ECG signal is detected using surface electrodes. As the signal is very feeble in amplitude so an instrumentation amplifier is designed to amplify the acquired ECG signal. Second order Butterworth filter is used to remove the noise present in it. Then, it is detected in MATLAB environment whether the patient is suffering from diseases like bradycardia and tachycardia using AGILENT 34972A LXI Data Acquisition Card (DAQ/DAS) with Bench Link Data Logger3 software. Next, human body temperature is measured using LM35DZ IC. After amplification, the temperature value is displayed on PC in both imperial and metric units using Graphical user interface (GUI) developed in Windows Visual Basic platform. Moreover, automatic and continuous monitoring of a patient's saline status is designed using IR trans-receiver block.
