Distribution of cardiac output to the brain across the adult lifespan

Journal of Cerebral Blood Flow and Metabolism, 2017
A widely accepted dogma is that about 15–20% of cardiac output is received by the brain in healthy adults under resting conditions. However, it is unclear if the distribution of cardiac output directed to the brain alters across the adult lifespan and is

A Narrative Review of Cardiac Output Measurement in Cardiac Surgery

Archives of Anesthesia and Critical Care, 2023
Continuous monitoring of the cardiovascular system and control of the changes affecting it is a constant challenge for the surgical team. The need to control the condition of the heart and better understand its condition is raised in the topic of ...

Cardiorenal syndrome type I recovery following heart rate correction: Cardiac output is not only stroke volume

Clinical Case Reports, 2022
Bradyarrhymias can result in low cardiac output state despite having a normal left ventricular ejection fraction and stroke volume. Because cardiac output is defined as the product of heart rate and stroke volume, a low cardiac output state caused by ...

Antiarrhythmic and proarrhythmic effects of subcutaneous nerve stimulation in ambulatory dogs [PDF]

, 2019
Background High output subcutaneous nerve stimulation (ScNS) remodels the stellate ganglia and suppresses cardiac arrhythmia. Objective To test the hypothesis that long duration low output ScNS causes cardiac nerve sprouting, increases plasma ...

Lower Cardiac Output Relates to Longitudinal Cognitive Decline in Aging Adults

Frontiers in Psychology, 2020
BackgroundSubclinical reductions in cardiac output correspond to lower cerebral blood flow (CBF), placing the brain at risk for functional changes.ObjectivesThis study aims to establish the consequences of reduced cardiac output on longitudinal cognitive

Machine Learning-based Signal Quality Assessment for Cardiac Volume Monitoring in Electrical Impedance Tomography [PDF]

arXiv, 2023
Owing to recent advances in thoracic electrical impedance tomography, a patient's hemodynamic function can be noninvasively and continuously estimated in real-time by surveilling a cardiac volume signal associated with stroke volume and cardiac output. In clinical applications, however, a cardiac volume signal is often of low quality, mainly because of
