In order to investigate the reliability of dye curve computer methods (Hewlett Packard computer ; HP and Gilford dye computer), simultaneous measurement of cardiac output, manual calculation by using whole blood calibration (WC) and dynamic calibration (DC) methods, was performed at rest in supine position in 18 subjects without intracardiac shunt. The cuvette dye-dilution curve was recorded by a Gilford dye densitometer, Model 140 Cardiac Output System. Determination of cardiac output by computers was performed by using HP and Gilford computers. Cardiac output by HP computer was significantly correlated with WC ; r=0.98,y=1.08x-0.06,p<0.001,and similar correlation was also obtained between Gilford computer and DC ; r=0.87,y=0.78x+1.89,p<0.001. Thus, the present data indicate that cardiac output measurement by computer methods is sufficiently reliable.
