BACKGROUND: Reliable measurement of cardiac output (CO) is important in the critically ill. Pulse contour-derived CO (PCCO) has been evaluated during stable hemodynamics, but is sensitive to changes in vascular tone and has not been validated under conditions of changing hemodynamics. Furthermore, PCCO requires calibration for the individual vascular impedance by transpulmonary thermodilution CO (TPCO), and the required frequency of recalibration to maintain accurate measurements, especially… Expand
Effect of norepinephrine dosage and calibration frequency on accuracy of pulse contour-derived cardiac output
TLDR
NE dosage, but not the time interval between calibrations, has an impact on the agreement between PCCO and COTCP, and the high NE dosage group showed significantly increased central artery stiffness. Expand
Reliability of continuous cardiac output measurement during intra-abdominal hypertension relies on repeated calibrations: an experimental animal study
TLDR
The CO obtained by uncalibrated PulseCO and PCCO failed to agree with COTCP during IAH and fluid loading, and in the critically ill patient, recalibration of continuous arterial waveform CO methods should be performed after fluid loading or before a major change in therapy is initiated. Expand
Comparison of non-calibrated pulse-contour analysis with continuous thermodilution for cardiac output assessment in patients with induced hypothermia after cardiac arrest.
TLDR
Induced hypothermia was not associated with increased bias or limits of agreement for the comparison of Vigileo and continuous thermodilution, but percentage error was high during normothermia and increased further during Hypothermia. Expand
Evaluation of cardiac output variations with the peripheral pulse pressure to mean arterial pressure ratio
TLDR
After positive fluid challenge or EP boluses, ΔPPrad/MAP was not as performant to track ΔCO which could make the use of this ratio difficult in current clinical practice. Expand
Arterial pressure-based cardiac output in septic patients: different accuracy of pulse contour and uncalibrated pressure waveform devices
TLDR
The pulse contour-derived cardiac index (CI) provided by the PiCCO device was reliable and accurate for assessing the CI changes induced by volume expansion and norepinephrine and the CIpw poorly tracked the trends in CI induced by those therapeutic interventions. Expand
A Comparison of Third-Generation Semi-Invasive Arterial Waveform Analysis with Thermodilution in Patients Undergoing Coronary Surgery
TLDR
It is demonstrated that uncalibrated semi-invasive monitoring system was able to reliably measure CI compared with transpulmonary thermodilution in patients undergoing elective coronary surgery and the semi-Invasive monitoring device was ableto track haemodynamic changes and trends. Expand
Performance of a new pulse contour method for continuous cardiac output monitoring: validation in critically ill patients.
TLDR
The performance of the new VolumeView™-CCO method is as reliable as the PiCCO2™- CCO pulse wave analysis in critically ill patients, however, an improved precision was observed with the Volume view technique. Expand
Cardiac output derived from arterial pressure waveform
TLDR
Although there are differences in invasiveness and the need for external calibration, all available devices provide parameters for enhanced hemodynamic monitoring and the ability of the arterial pressure waveform-based methods to guide goal-directed therapy is still unclear. Expand
Unreliability of pulse contour-derived cardiac output in piglets simulating acute hemorrhagic shock and rapid volume expansion.
TLDR
Pulse contour-derived hemodynamic parameters do not accurately reflect rapid hemodynamic changes, and the trend may be misleading in piglets, and Physicians are advised to interpret pulse contours with caution or to use invasive monitoring to guide treatment strategy therapy. Expand
Disagreement between pulse contour analysis and transpulmonary thermodilution for cardiac output monitoring after routine therapeutic interventions in ICU patients with acute circulatory failure
TLDR
In ICU patients requiring therapeutic interventions, COPC is frequently in disagreement with COTD, and the reliability of the pulse contour method for measuring cardiac output (CO) after different routinely used therapeutic interventions is assessed. Expand

TLDR
Arterial pulse contour analysis may allow for the use of arterial pressure waveforms to calculate stroke volume and its change during ventilation and would allow calculation of cardiac output changes and thus be a guide to assess global cardiovascular responsiveness to vasoactive therapies, such as fluid resuscitation and inotrope infusions.

Delayed Time Response of the Continuous Cardiac Output Pulmonary Artery Catheter
TLDR
Clinical important time delays in the response of the CCO catheter must be considered when rapid alterations of the hemodynamic state may occur, as shown in the current study. Expand

CO measurement by arterial pulse-contour analysis based on a new, improved algorithm is reliable, even in patients with profound changes of CO and during periods of hemodynamic instability. Expand

TLDR
PCCO and CCO provided comparable measurements during coronary bypass surgery and after marked changes in SVR, further calibration of the PCCO device is necessary. Expand

Femoral artery pulse contour CO correlates well with both COpa and COa even during substantial variations in vascular tone and hemodynamics, suggesting good agreement between the methods would indicate the potential of pulse contours analysis to monitor CO continuously and at reduced invasiveness.
