Overview
Brief Summary
The aim of our study was to evaluate the reliability of uncalibrated cardiac index monitoring based on arterial waveform analysis in patients undergoing off-pump coronary artery bypass grafting.
Detailed Description
Using contemporary statistical method the cardiac index values obtained via uncalibrated pulse contour analysis with Pro AQT system will be compared with traditional transpulmonary thermodilution technique (Pulsion, Germany).
