A Comprehensive Analysis of Forearm Impedance Plethysmography for the Maximally Non Invasive Monitoring and Measurement of Heart Pumping Function

Abstract

The main objective of this project is to measure the heart pumping function continuously and with maximally non-invasive methodology in a medical setting arrangement. Thus this paper is aimed to determine the study of impedance plethysmographic method to evaluate the stroke volume changes. In this paper the blood flow analysis has been carried out with fuzzy logic tool box with various activities such as Dehydration, Physical exercise, Cool skin, Warm Skin and breathes hold activity. Immediately after measuring the blood flow with the help of Impedance plethysmography, the end systolic and end diastolic values are obtained with the help of echocardiogram for the 18 subjects both in the normal condition and immediately after holding the breathe for 25 seconds. For the 18 subjects the correlation coefficient is obtained in a linear fashion between the changes in peak amplitude of forearm impedance plethysmographic waveform and changes in stroke volume before and after the 25 second breathe holding activity. Finally the forearm impedance plethysmographic waveform can be used to analyze the heart beat changes in Correlation with the changes in heart stroke volume. The process could be monitored for the series of cycles in determining the heart pumping performance.
