[Measurement of cardiac output by impedance cardiography. Experimental studies (author's transl)].
The correlation of impedance cardiography against electromagnetic flow measurement was studied in the pig. The conditions tested were normal circulation, hypo- und hypervolemia and acute pulmonary hypertension as well as the influence of respiration and electrodes location. Correct quantification of cardiac output was obtained only in normovolemic circulation during exspiration (r = 0,96, m = 1,15, b = 0,04).
