Determination and possibly monitoring of cardiac output (CO) is essential in cardiogenic shock (CS) and low-output heart failure (HF). The value of pulse contour analysis in these patients is unknown.
The aim of the present study was to assess the feasibility of LiDCO-pulse contour analysis in patients with CS and HF and to compare LiDCO with the standard pulmonary artery catheter (PAC).
A total of 27 patients (17 male, age 62 ± 13 years, SAPS II 52 ± 19; mechanical ventilation n = 24; CS and HF, group 1, n = 14; control, group 2, n = 13) and a total of 72 measurements were included (a mean of 2.17 consecutive measurements/patient). The CO was measured using PAC and LiDCO simultaneously in all patients. The LiDCO was calibrated according to the manufacturer.
There was a somewhat lower correlation between CO-PAC and CO-LiDCO in patients with CS and HF when compared with controls. From a clinical standpoint, agreement between the two methods was fairly good.
