Comparison of two minimally invasive cardiac-output monitoring systems with different algorithms

Fujita Medical Journal, 2016
Objectives: Minimally invasive haemodynamic monitoring is important in goal-directed therapy. The algorithms used by the FloTrac/Vigileo (FV) and lithium dilution cardiac output rapid (LiDCOrapid) (LR) measurement systems for cardiac output (CO ...

Safety of guidewire-based measurement of fractional flow reserve and the index of microvascular resistance using intravenous adenosine in patients with acute or recent myocardial infarction [PDF]

, 2016
Aims: Coronary guidewire-based diagnostic assessments with hyperemia may cause iatrogenic complications. We assessed the safety of guidewire-based measurement of coronary physiology, using intravenous adenosine, in patients with an acute coronary ...

The thermodilution method for the clinical assessment of cardiac output [PDF]

, 1995
The application of the thermodilution method in conditions associated with variations in blood flow implies a misuse of the Stewart Hamilton equation. Therefore, we studied the reliability of the thermodilution method for the estimation of mean cardiac ...

Microvascular Resistance Reserve for Assessment of Coronary Microvascular Function: JACC Technology Corner [PDF]

, 2021
The need for a quantitative and operator-independent assessment of coronary microvascular function is increasingly recognized. We propose the theoretical framework of microvascular resistance reserve (MRR) as an index specific for the microvasculature ...

Impact of shunt on the transpulmonary thermodilution curve [PDF]

Intensive Care Medicine, 2010
Dear Editor, We read with interest the comments by Nusmeier et al. [1] regarding our article entitled ‘‘Transpulmonary thermodilution curves for detection of shunt’’ [2]. The authors found that our explanation (Appendix, page 1086) was confused [2]! Thus, these authors proposed a much simpler and easier mathematical method to support our explanations ...

Thermodilution Cardiac Output: A Concept Over 250 Years in the Making

Cardiology in Review, 2019
The need to quantify blood flow through the heart has led to the development of different techniques for its measurement. The 3 main approaches are the Fick method, dye dilution, and thermodilution techniques.

New onset atrial fibrillation during orthotopic liver transplantation induced by iced saline injection for transpulmonary thermodilution: a case report

Journal of International Medical Research, 2022
Transpulmonary thermodilution is often used to measure extravascular lung water during liver transplantation. Here, the case of new onset atrial fibrillation during orthotopic liver transplantation, which may have been induced by iced saline injection ...

Cardiac index monitoring by pulse contour analysis and thermodilution after pediatric cardiac surgery [PDF]

, 2007
ObjectivesTo validate a new device (PiCCO system; Pulsion Medical Systems, Munich, Germany), we compared cardiac index derived from transpulmonary thermodilution and from pulse contour analysis in pediatric patients after surgery for congenital heart ...

Hemodynamic profiling by critical care echocardiography could be more accurate than invasive techniques and help identify targets for treatment

Scientific Reports, 2022
In this prospective observational study, non-invasive critical care echocardiography (CCE) was used to obtain quantitative hemodynamic parameters in 107 intensive care unit (ICU) patients; the parameters were then visualized in a novel web graph approach
