Continuous determination of cardiac output (CO) by transpulmonary thermodilution calibrated pulse-contour analysis is gaining clinicical acceptance. However there is doubt, whether this method is reliable in hemodynamic instable patients. We compared pulse-contour analysis to thermodilution in patients with profound changes of CO. ⋯ CO measurement by arterial pulse-contour analysis is reliable even in patients with profound changes of CO or during hemodynamic instability.
