Title: Innovations by James O. Elf in Cardiac Output Measurement

Introduction

James O. Elf is a notable inventor based in San Diego, CA, who has made significant contributions to the field of medical technology. He holds a total of 3 patents that focus on improving methods for determining cardiac output in living subjects. His work is essential for advancing non-invasive cardiac monitoring techniques.

Latest Patents

One of his latest patents is an "Apparatus and method for determining cardiac output in a living subject." This improved apparatus generally comprises one or more electrode assemblies or patches affixed to the skin of the subject in the vicinity of the thoracic cavity. In one embodiment, the apparatus includes a constant current source impedance cardiography (ICG) monitor adapted as a stand-alone system. In another embodiment, it comprises a module designed for use with a host monitoring system, which provides ECG, blood pressure, and other inputs to the module. The method also includes detecting a loss of electrical continuity in one or more terminals of the electrode patch and selecting between multiple signal inputs based on signal quality.

Another patent under his name is similar in focus, detailing an improved apparatus for determining cardiac output. This version emphasizes the importance of electrode patch design, where the terminals are in contact with an electrolytic gel and spaced a predetermined distance apart. This design allows for more consistent measurements and the detection of electrical continuity loss in clinical environments. The method involves generating and passing a stimulation current through the terminals and thoracic cavity, measuring impedance over time to determine cardiac muscle stroke volume, which is then used to calculate cardiac output.
