Hemodynamics monitoring—pulse-indicator continuous cardiac output versus pulmonary artery catheter

Objective To assess the accuracy of pulse-indicator continuous cardiac output (PiCCO) for the hemodynamics monitoring. Methods 30 critically ill patients with different etiological factors were admitted into intensive care unit. Hemodynamics of each patient was monitored by pulse-indicator continuous cardiac output and pulmonary artery catheter simultaneously. Correlation between the two methods was compared. Results Linear regression analysis revealed the two methods had good correlation [r=0.865 for cardiac output, r=0.879 for cardiac index, r=0.824 for stroke volume, r=0.833 for systemic vascular resistance]. Conclusion PiCCO can provide effectively hemodynamics monitoring for the management of the critical illness.
