Clinical evaluation of the FloTrac/Vigileo system and two established methods for continuous cardiac output monitoring in patients undergoing cardiac surgery

Abstract

A new arterial pressure waveform analysis device, which does not need external calibration (FloTrac/Vigileo; Edwards Lifesciences, Irvine, CA, USA), became recently available for cardiac output (CO) measurement. However, only limited validation data for this technique are so far available [1,2].
