Research utility of noninvasive methods for measurement of cardiac output.
Two noninvasive methods of cardiac index (Q) determination, pulsed Doppler echocardiography (QDop), and CO2 rebreathing (QCO2) were compared to dye dilution in eight normal volunteers. Measurements of Q were made by dye dilution (QDD) and the two noninvasive techniques under the following conditions: supine rest, after inflation of cuffs around the thighs, 35-degree head-up tilt, supine rest re...
متن کاملComparison between Flotrac-Vigileo and Bioreactance, a totally noninvasive method for cardiac output monitoring
INTRODUCTION This study was designed to compare the clinical acceptability of two cardiac output (CO) monitoring systems: a pulse wave contour-based system (FloTrac-Vigileo) and a bioreactance-based system (NICOM), using continuous thermodilution (PAC-CCO) as a reference method. METHODS Consecutive patients, requiring PAC-CCO monitoring following cardiac surgery, were also monitored by the tw...
متن کاملEsophageal Doppler: noninvasive cardiac output monitor.
In this article we describe the esophageal Doppler, a noninvasive, instantaneous cardiac output monitor. Its reliability has been demonstrated to be comparable to that of other current techniques used in the clinical arena to measure cardiac output. It helps guiding intravascular fluid resuscitation by quantifying the increase in flow in response to fluid challenges and by indicating the platea...
متن کاملNoninvasive cardiac output monitors: a state-of the-art review.
1 o i C m m n a i w t i e d s DESPITE IMPROVEMENTS in resuscitation and supportive care, progressive organ dysfunction occurs in a large proportion of patients with acute, life-threatening illnesses and those undergoing major surgery.1-5 Recent data suggest that early aggressive resuscitation of critically ill patients may limit and/or reverse tissue hypoxia and progression to organ failure and...
متن کاملPerformance of noninvasive partial CO2 rebreathing cardiac output and continuous thermodilution cardiac output in patients undergoing aortic reconstruction surgery.
BACKGROUND In the partial CO(2) rebreathing method, monitored changes in CO(2) elimination and end-tidal CO(2) in response to a brief rebreathing period are used to estimate cardiac output. However, dynamic changes in CO(2) production during ischemia and reperfusion may affect the accuracy of these estimates. This study was designed to compare measurements of cardiac output as produced by the p...
