Validation of a new spectrometer for noninvasive measurement of cardiac output [PDF]

, 2004
Acetylene is a blood-soluble gas and for many years its uptake rate during rebreathing tests has been used to calculate the flow rate of blood through the lungs (normally equal to cardiac output) as well as the volume of lung tissue.

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

The effects on arterial haemoglobin oxygen saturation and on shunt of increasing cardiac output with dopamine or dobutamine during one-lung ventilation [PDF]

, 2004
Publisher's copy made available with the permission of the publisher © Australian Society of AnaesthetistsTheoretically, if the cardiac output were increased in the presence of a given intrapulmonary shunt, the arterial saturation should improve as the ...

The effect of age on the relationship between cardiac and vascular function [PDF]

, 2015
Age-related changes in cardiac and vascular function are associated with increased risk of cardiovascular mortality and morbidity. The aim of the present study was to define the effect of age on the relationship between cardiac and vascular function ...

Lactate acidosis and cardiac output during initial therapeutic cooling in asphyxiated newborn infants.

PLoS ONE, 2019
AimWe hypothesized that compromised cardiac output in asphyxiated infants may influence on the rate of disappearance of lactate due to insufficient perfusion.MethodsThe study was a prospective, observational study, where infants with perinatal asphyxia ...

Cardiac Output Monitoring in Preterm Infants

Frontiers in Pediatrics, 2018
Maintaining optimal circulatory status is a key component of preterm neonatal care. Low-cardiac output (CO) in the preterm neonate leads to inadequate perfusion of vital organs and has been linked to a variety of adverse outcomes with heightened acute ...

A cortical potential reflecting cardiac function [PDF]

, 2007
Emotional trauma and psychological stress can precipitate cardiac arrhythmia and sudden death through arrhythmogenic effects of efferent sympathetic drive. Patients with preexisting heart disease are particularly at risk.
