Experiments were conducted in 6 anesthetized dogs to study the validity of cardiac output estimation by pulse contour method (Warner's method), comparing with the dye dilution method, after atrial pacing, Dextran infusion, hemorrhage, occlusion of the thoracic aorta by a balloon catheter, artificial arterio-venous shunt and infusion of isoproterenol and noradrenalin. The central aortic pressure was recorded by a catheter-tip manometer (Miller PC-77). Warner's method used was the pulse pressure method and systolic area method. Warner's method, especially pulse pressure method significantly correlated with the cuvette dye dilution method except for occlusion of the thoracic aorta and hemorrhage. The value of capacitance had to be lesser in occlusion of the thoracic aorta and larger in hemorrhage. Thus, it is concluded that Warner's method is reliable for instantaneous measurement of cardiac output, unless there is the special hemodynamic change such as occlusion of the aorta and hemorrhage.
