AB  - We have compared the accuracy of two methods of measuring cardiac output, 
      thoracic electrical bioimpedance (TEB) and thermodilution (TD), in pigs. We 
      studied four anaesthetized pigs, producing 145 paired cardiac output values over 
      a range of TD cardiac outputs of 2.6-12.6 litre min-1. TEB cardiac output was 
      less than that measured by TD, by a constant factor throughout the observed range 
      of values, because of differences in porcine thoracic shape. The Pearson product 
      moment correlation coefficient suggested a good correlation (r = 0.984, P < 
      0.001). More importantly, analysis by the Bland and Altman statistical method 
      suggested a high level of agreement, with 95% confidence intervals of +/- 1.0 
      litre min-1. These results suggest that TEB can be used as a satisfactory method 
      to measure cardiac output in porcine models.
