Open Access Abstract Introduction Cardiac output CO monitoring is indicated only in selected patients. In cardiac surgical patients perioperative haemodynamic management is often guided by CO measurement by pulmonary artery catheterisation COPAC . Alternative strategies of CO determination have become increasingly accepted in clinical practice because the benefit of guiding therapy by data derived from the PAC remains to be proven and less invasive alternatives are available. Recently a device offering uncalibrated CO measurement by arterial waveform analysis COWave was introduced. As far as this approach is concerned however the validity of the CO measurements obtained is utterly unclear. Therefore the aim of this study was to compare the bias and the limits of agreement LOAs two .
