Abstract :
An impedance cardiography (ICG) prototype system developed for the purpose of critical-care monitoring is discussed. This system´s operations is completely technician-free, providing a continuous display with digital results and four-channel color waveforms. From 20 patients all with Swan-Ganz catheters in their hearts, 82 correlation studies are reported, showing encouraging results with respect to accuracy as well as on system reproducibility. An anatomically specified electrode configuration allowing precise and reproducible positioning of the electrodes is defined
