Journal of Intensive Care, 2019 Background Despite the evidence for calibrated cardiac monitored devices to determine fluid responsiveness, there is minimal evidence that the use of cardiac output monitor devices leads to an overall change in IV fluid use.

Scapular renal cell carcinoma metastasis as a cause of high-output heart failure: a case report
BMC Cardiovascular Disorders, 2022 Background High-output heart failure is a rare condition that occurs when the heart is unable to respond to a sustained increase in blood demand. On echocardiography, a cardiac index of > 4 L/min/m2 (or 6 L/min) is a clear indicator of this disorder. The

Mathematical and Preclinical Investigation of Respiratory Sinus Arrhythmia Effects on Cardiac Output [PDF]
arXiv, 2020 Respiratory sinus arrhythmia (RSA) is heart rate variability in synchrony with respiration although its functional significance not clear. The loss of sinus arrhythmia may indicate underlying heart failure or disease; therefore, there would be a great advantage of knowing how it works and affects the cardio-respiratory system, especially by providing a

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background Objective markers of cardiac function are limited in the outpatient setting and may be beneficial for monitoring patients with chronic cardiac conditions.

Simulating Cardiac Fluid Dynamics in the Human Heart [PDF]
arXiv, 2023 Cardiac fluid dynamics fundamentally involves interactions between complex blood flows and the structural deformations of the muscular heart walls and the thin, flexible valve leaflets. There has been longstanding scientific, engineering, and medical interest in creating mathematical models of the heart that capture, explain, and predict these fluid ...

Predictors of low cardiac output in decompensated severe heart failure
Clinics, 2011 OBJECTIVE: To identify predictors of low cardiac output and mortality in decompensated heart failure. INTRODUCTION: Introduction: Patients with decompensated heart failure have a high mortality rate, especially those patients with low cardiac output ...

A staggered-in-time and non-conforming-in-space numerical framework for realistic cardiac electrophysiology outputs [PDF]
arXiv, 2023 Computer-based simulations of non-invasive cardiac electrical outputs, such as electrocardiograms and body surface potential maps, usually entail severe computational costs due to the need of capturing fine-scale processes and to the complexity of the heart-torso morphology. In this work, we model cardiac electrical outputs by employing a coupled model

Validation of a continuous, arterial pressure-based cardiac output measurement: a multicenter, prospective clinical trial [PDF]
, 2007 INTRODUCTION: The present study compared measurements of cardiac output by an arterial pressure-based cardiac output (APCO) analysis method with measurement by intermittent thermodilution cardiac output (ICO) via pulmonary artery catheter in a clinical ...

British Journal of Anaesthesia, 1970 SUMMARY A comparatively simple mathematical expression has been devised for the computation of the area under the cardiac output curve which is easy to use, quick to give a result, and yet is comparable in accuracy to other methods of determining cardiac output when the dye dilution technique is used.
