Background: Assessment of cardiac output (CO) by the FloTrac/Vigileo system may offer a less invasive means of determining the CO than either the pulmonary artery catheter (PAC) or the PiCCOplus system. The aim of this study was to compare CO measurements made using the FloTrac/Vigileo system with upgraded software (FCO, Edwards Lifesciences, Irvine CA, USA), the PiCCOplus system (PCO, Pulsion Medical Systems, Munich, Germany) and continuous CO monitoring using a PAC (CCO; Vigilance monitoring, Edwards Lifesciences, Irvine CA, USA) with intermittent pulmonary artery thermodilution (ICO). The study was conducted in patients undergoing elective cardiac surgery.
Methods: Thirty-one patients with preserved left ventricular function were enrolled. CCO, FCO, and PCO were recorded in the perioperative period at six predefined time points after achieving stable haemodynamic conditions; ICO was determined from the mean of three bolus injections. Bland-Altman analysis was used to compare CCO, FCO, and PCO with ICO.
Results: Bland-Altman analysis revealed a comparable mean bias and limits of agreement for all tested continuous CO monitoring devices using ICO as reference method. Agreement for all devices decreased in the postoperative period.
Conclusion: The performance of the FloTrac/Vigileo system, the PiCCOplus, and the Vigilance CCO monitoring for CO measurement were comparable when tested against intermittent thermodilution in patients undergoing elective cardiac surgery.

Introduction: Dynamic indices of fluid responsiveness (FR) such as pulse pressure variation (PPV) and stroke volume variation (SVV) differ among hemodynamic monitors, which use proprietary algorithms, and vary even over a short period of time. We aimed to compare the baseline values, fluctuation and predictive value for FR of PPV and SVV measured by three minimally invasive monitors.
Patients And Methods: Twenty patients undergoing high-risk abdominal surgery were included and 45 fluid challenges were analysed.

Background: Hypotension during dialysis arises from vasomotor tone alterations and hypovolemia, with disrupted counterregulatory mechanisms in acute kidney injury (AKI) patients. This study investigated the predictive value of preload dependency, assessed by the passive leg raising (PLR) test, and arterial tone, measured by dynamic elastance (Eadyn), for intradialytic hypotension (IDH).
Methods: In this prospective observational study conducted in a tertiary hospital ICU, hemodynamic parameters were collected from critically ill AKI patients undergoing intermittent hemodialysis using the FloTrac/Vigileo system.

Article Synopsis
- The study by Chahyun Oh et al. compares two methods of measuring cardiac output during surgery: the FloTrac system and continuous thermodilution.
- The researchers analyzed data collected in real-time to improve the accuracy of these measurements.
- The findings highlight potential differences in cardiac output estimates between the two systems, which could impact clinical practices in monitoring patient health.

(1) Background: Previous studies reported limited performance of arterial pressure waveform-based cardiac output (CO) estimation (FloTrac/Vigileo system; CO-FloTrac) compared with the intermittent thermodilution technique (CO). However, errors due to bolus maneuver and intermittent measurements of CO could limit its use as a reference. The continuous thermodilution technique (CO) may relieve such limitations.
