Title: The Innovative Contributions of Stephen R. Barnes in Cardiac Monitoring
Introduction
Stephen R. Barnes is a notable inventor based in Seattle, WA, who has made significant strides in the field of cardiac monitoring. With a total of five patents to his name, Barnes has developed groundbreaking methods and devices that enhance the accuracy and efficiency of cardiac output measurement, ultimately contributing to better patient care.
Latest Patents
Barnes’ latest patents include innovative methodologies and apparatuses designed to monitor cardiac output effectively. One of his notable inventions describes a method that involves measuring the systolic velocity of blood flowing through the patient's descending aorta. This is combined with determining the cross-sectional area of the ascending aorta to calculate the cardiac output. An important aspect of this patent is the ability to convert the cardiac output into cardiac index and systemic vascular resistance based on the patient's body surface area and blood pressure.
Another significant patent is the development of noninvasive ultrasonic probes tailored to insonify the ascending aorta of supine or reclining patients. This probe integrates transducers that both insonify and intercept doppler-shifted energy reflected from the surrounding aorta walls and the blood flow. The unique design of the probe head minimizes discomfort during use, allowing healthcare professionals to easily maneuver and align the ultrasonic energy beam with the patient's anatomy.
