Continuous cardiac output measurement: pulse contour analysis vs thermodilution technique in cardiac surgical patients

Abstract: 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%, respectively) at 12 selected times. During operation, mean differences (bias) between PCCO-BCO and CCO-BCO did not dif… Show more

“…However, the arterial pressure waveform often changes during surgery because the arterial compliance changes according to sympathetic activity, intravascular blood volume, position, etc. [3][4][5] These factors may induce miscalculation of the CO by PulseCO™ because of inaccurate estimation of pulse wave velocity. 2 The purpose of the present study was to determine whether CO measured by the PulseCO™ is interchangeable with CO measured by the bolus thermodilution method with the Vigilance™ monitor (Edwards Lifesciences LLC, Irvine, CA, USA) in patients undergoing OPCAB.…”

“…In contrast, the PiCCO system (Pulsion Medical Systems AG, Munich, Germany) relies on a contourbased algorithm based on the Wesseling algorithm [18]. Recalibration is recommended when there are changes of more than 50% in arterial blood pressure [19]. The Vigileo Ò ⁄ FloTrac TM monitor (Edwards Lifesciences, Irvine, CA, USA) is again based on the Wesseling algorithm and has recently been the subject of software improvements and revisions [20,21], but (re)calibration is not possible.…”

“…The target value of mean arterial blood pressure (MAP) is at least 65mmHg and should be individualized, lower in unstopped bleeding source and higher in hypertensive patients or patients with clinical improvement under these higher pressures [22]. A central venous catheter (CVC) is usually used for CVP measurement, ScvO2 measurements, vasopressor and/or inotrope therapy administration.…”
