Possible indications would be measurement of cardiac output, asymmetric heart failure (right ⱡ left), complex hemodynamic instability, certain forms of shock, heart surgery in complex valve interventions and pulmonary hypertension, differentiation of cardiogenic from non-cardiogenic pulmonary edema and differentiated therapy of acute pulmonary hypertension. The basic principle behind the Swan-Ganz catheter is the Stewart-Hamilton equation, but here the temperature difference, volume, distribution and time are measured from the proximal and distal parts of the catheter.
