Title: Innovations in Cardiac Monitoring by J David Schaffer

Introduction

J David Schaffer is an accomplished inventor based in Vestal, NY (US). He has made significant contributions to the field of cardiac monitoring, holding 2 patents that focus on non-invasive methods for estimating cardiac output.

Latest Patents

One of Schaffer's latest patents is a system and method for infrasonic cardiac monitoring. Cardiac Output (CO) has traditionally been difficult, dangerous, and expensive to obtain. Surrogate measures such as pulse rate and blood pressure have therefore been used to permit an estimate of CO. MEMS technology, evolutionary computation, and time-frequency signal analysis techniques provide a technology to non-invasively estimate CO, based on precordial (chest wall) motions. The technology detects a ventricular contraction time point and stroke volume from chest wall motion measurements. As CO is the product of heart rate and stroke volume, these algorithms permit continuous, beat-to-beat CO assessment. Nontraditional Wavelet analysis can be used to extract features from chest acceleration. A learning tool is preferable to define the packets which best correlate to contraction time and stroke volume.
