Abstract

A system for measuring of cardiac output and cardiac performance parameters based on a cardiac blood flow balance parameter between a right chamber of the heart and a left chamber of the heart, includes a sensor device for measuring one of blood pressure and blood flow rate and blood constituent concentration of a patient so as to generate an arterial pulse signal. A processing unit is responsive to the arterial pulse signal for generating a full arterial pulse signal, an arterio-venous pulse signal, and a balance parameter. A computational device is responsive to the balance parameter for further generating cardiac output and a set of cardiac performance parameters. A display station device is responsive to the set of physiological parameters from the computational device for displaying meaningful information.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is a non-provisional application which claims the benefits of provisional application Ser. No. 61 / 700,892 filed on Sep. 14, 2012.BACKGROUND OF THE INVENTION

[0002] 1. Technical Field

[0003] This invention relates generally to methods, devices, and systems used in the field of cardiovascular medicine for clinically assessing of a patient's health condition. More particularly, it relates to a new and improved system and method for monitoring cardiac blood flow balance between the right and left heart chambers based on arterial pulse waveforms representing blood pressure or flow or constituent concentration per cardiac cycle.

[0004] The description below is merely provided for general background information and for assisting in understanding the technical field to which the present invention is related. As is generally known in the art, the circulatory system in human beings is responsible for transporting oxygen and other nutrien...

Embodiment Construction

[0044]Before explaining the disclosed embodiments in detail, it is to be distinctly understood at the outset that the present invention shown in the drawings and predominantly described in detail in association with a system for measuring of cardiac blood flow balance parameter is not intended to serve as a limitation upon the scope or teachings thereof, but is to be considered merely for the purpose of convenience of illustration of one example of its application. In particular, the present invention may be applied to any other suitable physiological monitoring systems, such as oximetry systems, ECG systems, and any other suitable for monitoring of a patient's liver, heart, lungs, brain, kidneys and other organs of the body.

[0045]Historically, the dicrotic notch was thought to represent a reflection of a fast pressure pulse that is generated when the aortic valve opens above its cracking pressure, and blood pressure reflecting backward from the arterial side back toward the aorta. ...
