Non-invasive Cardiac Output Monitoring in Neonates
Frontiers in Pediatrics, 2021 Circulatory monitoring is currently limited to heart rate and blood pressure assessment in the majority of neonatal units globally. Non-invasive cardiac output monitoring (NiCO) in term and preterm neonates is increasing, where it has the potential to ...

Validation of continuous cardiac output technologies: consensus still awaited. [PDF]
, 2009 An ability to measure cardiac output in a continuous and non-invasive fashion is eagerly awaited in the field of intensive care practice. Modern technologies purport to be able to do this, but the design of studies that validate the manufacturers' claims

Frontiers in Physiology, 2021 We wanted to demonstrate the relationship between blood volume, cardiac size, cardiac output and maximum oxygen uptake (V.O2max) and to quantify blood volume shifts during exercise and their impact on oxygen transport.

A prospective study to evaluate the accuracy of pulse power analysis to monitor cardiac output in critically ill patients [PDF]
, 2008 Background Intermittent measurement of cardiac output may be performed using a lithium dilution technique (LiDCO). This can then be used to calibrate a pulse power algorithm of the arterial waveform which provides a continuous estimate of this variable ...

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 ...

Pulse pressure analysis: to make a long story short. [PDF]
, 2010 Pulse pressure analysis algorithms are commonly used to measure cardiac output and to allow for the rational titration of therapy in critically ill patients. The ability of these algorithms to accurately track changes in stroke volume (and cardiac output)

Heart, 1998 Over 100 years ago Karl Ludwig stated that: The fundamental problems in the circulation derive from the fact that the supply of adequate amounts of blood to the organs of the body is the main purpose of the circulation while the pressures that are necessary to achieve it are of secondary importance; but the measurement of flow is difficult while that ...

Bench-to-bedside review: The importance of the precision of the reference technique in method comparison studies - with specific reference to the measurement of cardiac output. [PDF]
, 2009 Bland-Altman analysis is used for assessing agreement between two measurements of the same clinical variable. In the field of cardiac output monitoring, its results, in terms of bias and limits of agreement, are often difficult to interpret, leading ...

Intensive Care Medicine Experimental, 2020 Background Positive end-expiratory pressure (PEEP) is used to optimize oxygenation by preventing alveolar collapse. However, PEEP can potentially decrease cardiac output through cardiopulmonary interactions.

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 ...
