TI  - Equivalence of bioimpedance and thermodilution in measuring cardiac index after 
      cardiac surgery.
PG  - 8-14
AB  - OBJECTIVE: To compare thoracic electrical bioimpedance (TEB) cardiography versus 
      pulmonary artery thermodilution (TD) derived cardiac index in patients after 
      cardiopulmonary bypass. DESIGN: Prospective, blinded electronic data collection. 
      SETTING: Intensive care unit of a military hospital. PARTICIPANTS: 
      Post-cardiopulmonary bypass patients for primary comparison between technologies 
      (n = 20) and patients for comparison of variability within each technology (n = 
      20). INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Cardiac index values by 
      TEB or TD were collected simultaneously. Linear regression, Lin's concordance 
      correlation coefficient, bias, and precision measures within the large data set 
      group and within each patient over time were calculated. Linearity in regression 
      and Lin's concordance correlation coefficient of 0.99 were shown. A bias of 0.07 
      L/min/m(2) and precision of 0.40 L/min/m(2) were within acceptable clinical 
      limits, as were equivalence test results. CONCLUSIONS: TEB is equivalent to 
      TD-derived cardiac index in postoperative cardiac surgery patients.
