AB  - OBJECTIVE: To determine the reliability of whole-body impedance cardiography 
      (ICGWB), with electrodes attached to wrists and ankles, in the measurement of 
      cardiac output (CO) on the basis of simultaneous comparison with thermodilution 
      (TD) and direct oxygen Fick (Fick) methods. DESIGN: Prospective clinical study. 
      SETTING: A surgical intensive care unit at a university hospital. PATIENTS: 
      Thirty consecutive subjects undergoing a coronary artery bypass surgery were 
      investigated preoperatively. MEASUREMENTS: ICGWB derived CO was measured 
      simultaneously with the TD and Fick methods to establish the biases and limits of 
      agreement (LA) between the methods. RESULTS: The results obtained by ICGWB and 
      the invasive methods showed good agreement. The bias and LA between COTD and 
      COICG were 0.00 l/min: 1.37 and 1.37 l/min, respectively, and were close to those 
      obtained between COTD and COFICK, 0.32 l/min; 1.74 and -1.10 l/min. The bias and 
      LA between the COFICK and COICG were -0.32 l/min; -2.24 and 1.60 l/min 
      respectively. The repeatability value of consecutive single measurements for 
      ICGWB (RVICG = 0.57 l/min) was much better than for the TD method (RVTD = 1.10 
      l/min). CONCLUSION: There was close agreement between the results of the three 
      methods in the measurement of CO. In sedated preoperative patients the accuracy 
      of ICGWB is within clinically acceptable limits and its repeatability is 
      excellent. ICGWB provides a useful alternative to the TD and Fick methods in 
      cases where the pressures supplied by the pulmonary artery catheter are not 
      essential.
