Why the study?
Do pulse contour analysis and uncalibrated arterial pressure waveform devices accurately track changes in cardiac index compared to transpulmonary thermodilution in patients with septic circulatory failure?
Population
80 patients with septic circulatory failure
Comparison

May favor PiCCO over Vigileo for CI tracking in septic failure; leaves open randomized outcome trials.
Do pulse contour analysis and uncalibrated arterial pressure waveform devices accurately track changes in cardiac index compared to transpulmonary thermodilution in patients with septic circulatory failure?
In patients with septic circulatory failure, the PiCCO device accurately tracks cardiac index changes induced by volume expansion and norepinephrine, whereas the Vigileo device is unreliable for this purpose.
