Synchronizing cardiovascular sensors for cardiovascular monitoring

Abstract

This document describes synchronizing cardiovascular sensors for cardiovascular monitoring, such as through sensing relevant hemodynamics understood by pulse transit times, blood pressures, pulse-wave velocities, and, in more breadth, electrical conduction properties, cardiac rhythms, thoracic impedance, ballistocardiograms and pressure-volume loops. The techniques disclosed in this document use various cardiovascular sensors to sense hemodynamics, such as skin color and skin and other organ displacement. These cardiovascular sensors require little if any risk to the patient and are simple and easy for the patient to use.

Description

technical field [0001] This application claims priority under 35 U.S.C. Section 119(e) to US Patent Application Serial No. 14 / 720,632, filed May 22, 2015, the disclosure of which is hereby incorporated by reference in its entirety. Background technique [0002] Cardiovascular disease is a leading cause of morbidity and mortality worldwide. At the same time, this chronic disease is largely preventable. Medical science knows how to save most lives by eliminating major risk factors for smoking, diabetes, and high blood pressure. Additionally, many people are told what they need to do to reduce these risk factors - quit smoking, reduce sugar intake, eat healthier, reduce alcohol intake, increase cardiovascular activity, lose weight, and take blood pressure medication if needed. However, many people do not follow this good advice. As a result, millions of people die unnecessarily from cardiovascular disease. [0003] People don't follow this good medical advice because they t...

[0005] Another reason people don't follow this good advice or don't follow it long enough to prevent heart disease is because they don't see the benefit

When people make dietary and habit changes that most people don't want to make, they often don't see improvement until they lose motivation to continue monitoring their cardiovascular status
