We examined the stability of two pulse contour analysis devices (PCA; PiCCOplus- and FloTrac-system) measuring cardiac output (CO) compared to transcardiopulmonal thermodilution (TPTD) in 28 critically ill patients. After an initial calibration of the PiCCO-PCA we compared the two devices with TPTD-COs every 4 hours without recalibration. The PiCCO-PCA showed a better match than the FloTrac-PCA. A fixed recalibration frequency can't be specified, but large changes in patient's hemodynamic situation should entail recalibration. If the FloTrac-PCA received an initial calibration, we would expect a better performance.
