Measurement of cardiac output: a comparison between transpulmonary thermodilution and uncalibrated pulse contour analysis.
BACKGROUND Recently, continuous monitoring of cardiac output (CO) based on pulse contour analysis (Vigileo) has been introduced into practice. In this clinical study, we evaluated the accuracy of this system by comparing it with the transpulmonary thermodilution technique (TPID) in septic patients. METHODS We studied 24 mechanically ventilated patients with septic shock (16 male, 8 female, ag...
متن کاملContinuous cardiac output measurement: pulse contour analysis vs thermodilution technique in cardiac surgical patients.
We have analysed the clinical agreement between two methods of continuous cardiac output measurement pulse contour analysis (PCCO) and a continuous thermodilution technique (CCO), were both compared with the intermittent bolus thermodilution technique (BCO). Measurements were performed in 26 cardiac surgical patients (groups 1 and 2, 13 patients each, with an ejection fraction > 45% and < 45%, ...
متن کاملArterial pressure-based cardiac output in septic patients: different accuracy of pulse contour and uncalibrated pressure waveform devices
INTRODUCTION We compared the ability of two devices estimating cardiac output from arterial pressure-curve analysis to track the changes in cardiac output measured with transpulmonary thermodilution induced by volume expansion and norepinephrine in sepsis patients. METHODS In 80 patients with septic circulatory failure, we administered volume expansion (40 patients) or introduced/increased no...
متن کاملComparison between pulse waveform analysis and thermodilution cardiac output determination in patients with severe pre-eclampsia.
BACKGROUND This study compared cardiac output (CO) measurements derived from pulse waveform analysis with values obtained by thermodilution (TD), in patients with post-partum complications of severe pre-eclampsia. METHODS Eighteen patients were recruited, 24-96 h post-delivery. After central venous calibration of the pulse waveform analysis monitor (LiDCOplus), CO readings were compared with ...
متن کاملComparison of uncalibrated arterial waveform analysis in cardiac surgery patients with thermodilution cardiac output measurements
INTRODUCTION Cardiac output (CO) monitoring is indicated only in selected patients. In cardiac surgical patients, perioperative haemodynamic management is often guided by CO measurement by pulmonary artery catheterisation (COPAC). Alternative strategies of CO determination have become increasingly accepted in clinical practice because the benefit of guiding therapy by data derived from the PAC ...
