AB  - OBJECTIVES: To compare cardiac output (CO) measurements from a novel endotracheal 
      bioimpedance cardiac output monitor device (ECOM; ConMed, Irvine, CA) to 
      simultaneous pulmonary artery thermodilution (TD) CO. DESIGN: Prospective study. 
      SETTING: One academic hospital. PARTICIPANTS: Forty volunteer patients undergoing 
      cardiac surgery. INTERVENTIONS: Intraoperative CO measurements. MEASUREMENTS AND 
      MAIN RESULTS: Simultaneous comparative data points were collected from ECOM and 
      TD at 4 periods: post-induction, post-sternotomy, post-cardiopulmonary bypass, 
      and post-chest closure. The mean CO(TD) was compared with CO(ECOM) for each 
      operative period then assessed for agreement by linear regression, Bland-Altman 
      analysis, and percent error methods. There were 35 men (87.5%) with a mean age of 
      66 +/- 10.7 years in the present study population. R values (p value) for the 4 
      time periods were 0.50 (0.002), 0.33 (0.035), 0.42 (0.007), and 0.48 (0.002). 
      Bias and 95% limits of agreement in L/min were -0.11 (-2.40 to 2.18), 0.04 (-2.57 
      to 2.65), -0.06 (-2.86 to 2.74), and 0.02 (-2.42 to 2.45). Percent errors of the 
      4 time periods were 51%, 53%, 50%, and 48%. CONCLUSIONS: ECOM did not adequately 
      agree with TD in patients undergoing cardiac surgery.
