Health and Disease Monitoring in the Heart and the Aorta Based on Model-Based Ballistocardiogram Analysis

Executive SummaryBallistocardiogram (BCG) is a recording of cardiac force exerted on the body due to the ejection of blood by the heart. Researchers at Michigan State University, University of Maryland, and Georgia Institute of Technology have developed a new method to analyze the BCG signal to detect abnormalities of blood pressure associated with...

Methods and Apparatus for Determining Cuff Blood Pressure

IntroductionBlood pressure cuffs are standard equipment that can be found in hospitals, clinics and stores selling medical supplies. Patients that need to closely monitor their blood pressure may also have one at home. These cuffs employ oscillometry to measure both systolic and diastolic blood pressure by inflating the cuff to a certain pressure. Because...

Methods and Apparatus for Determining Cuff-Less Blood Pressure

IntroductionBlood pressure provides health care professionals with basic, yet essential information about a patient's health and well-being. For some high risk patients, blood pressure must be consistently and in some cases constantly monitored, usually requiring an intra-arterial catheter. Traditional blood pressure cuffs are insufficient for these...

Determining Ejection Fraction Volumes on a Continuous Basis

IntroductionPeople with progressive heart failure need ejection fraction (EF) measurements as critical information in diagnosis and treatment. EF is the percentage of the total volume in a ventricular chamber of the heart that is ejected per beat, a key measure of overall heart function. A technology allowing continuous monitoring of EF would allow...

Continuous Monitoring of Cardiac Output and Left Atrial Pressure

IntroductionCardiac output (CO) is the volume of blood ejected by the heart per unit time, while left atrial pressure (LAP) is the blood pressure in the left heart during the cardiac filling phase. Both CO and LAP permit the diagnosis of various cardiovascular disease processes and thereby facilitate imminent therapeutic decisions. Thus, the ability...
