Journal ArticleDOI
Cardiac output method comparison studies: the relation of the precision of agreement and the precision of method
TL;DR: A decomposition of variance shows that method agreement does not only depend on the precision of method but also on another important source of variability, i.e., the method’s general variability about the true values.
Journal ArticleDOI
Assessment of cardiovascular function from multi-Gaussian fitting of a finger photoplethysmogram.
R. Couceiro,Paulo Carvalho,Rui Pedro Paiva,Jorge Henriques,I. Quintal,Manuel J. Antunes,Jens Muehlsteff,Christian Eickholt,Christoph Brinkmeyer,Malte Kelm,Christian Meyer +10 more
TL;DR: A new method for the extraction of cardiovascular performance surrogates from analysis of the photoplethysmographic (PPG) signal alone using a multi-Gaussian (MG) model consisting of five Gaussian functions to decompose the PPG pulses into its main physiological components is proposed.
Journal ArticleDOI
III. Are we ready for the age of non-invasive haemodynamic monitoring?
Bernd Saugel,D.A. Reuter +1 more
TL;DR: Benefits and risks of using dexamethasone as a local anaesthetic adjuvant for brachial plexus block, and a systematic review and meta-analysis of randomized controlled trials.
Journal ArticleDOI
A comparison of volume clamp method-based continuous noninvasive cardiac output (CNCO) measurement versus intermittent pulmonary artery thermodilution in postoperative cardiothoracic surgery patients.
Julia Y. Wagner,Annmarie Körner,Leonie Schulte-Uentrop,Mathias Kubik,Hermann Reichenspurner,Stefan Kluge,Daniel A. Reuter,Bernd Saugel +7 more
TL;DR: In this clinical study in cardiothoracic surgery patients, CNCOcal showed good agreement when compared with PAC-CO, and for CNCObio, the higher percentage error and good trending ability were observed.
Journal ArticleDOI
Electrical velocimetry for noninvasive cardiac output and stroke volume variation measurements in dogs undergoing cardiovascular surgery
TL;DR: In dogs undergoing cardiovascular surgery, EV provided accurate CO measurements compared with CIPAC, although its trending ability was poor, and SVV by EV, but not CVP, reliably predicted fluid responsiveness during mechanical ventilation in dogs.

Minimally invasive measurement of cardiac output during surgery and critical care: a meta-analysis of accuracy and precision.
Philip J Peyton,Simon W Chong +1 more
TL;DR: None of the four minimally invasive methods adapted for use during surgery and critical care has achieved agreement with bolus thermodilution which meets the expected 30% limits.
Journal ArticleDOI
Measurement of cardiac output before and after cardiopulmonary bypass: Comparison among aortic transit-time ultrasound, thermodilution, and noninvasive partial CO2 rebreathing
TL;DR: Comparing the agreement among NICO, bolus (TDCO), and continuous thermodilution (CCO), with transit-time flowmetry of the ascending aorta using an ultrasonic flow probe (UFP) before and after cardiopulmonary bypass (CPB) found the accuracy for all 3 techniques was similar.
Journal ArticleDOI
comparison of invasive and less-invasive techniques of cardiac output measurement under different haemodynamic conditions in a pig model
TL;DR: The data suggest that pulmonary arterial thermodilution and PiCCO™ may be interchangeably used for cardiac output measurement even under acute haemodynamic changes.
