TI  - Comparison of two impedance cardiographic techniques for measuring cardiac output 
      in critically ill patients.

AB  - The purpose of the present study was to compare cardiac output (Q) values 
      obtained by both the Kubicek (MIC) and Sramek (NCCOM3) impedance cardiographic 
      techniques with thermodilution (TD) in critically ill patients. The two impedance 
      techniques were also compared in normal subjects. Seven healthy subjects and ten 
      ICU patients were enlisted in the study. Three Q measurements were made in each 
      subject. In the ICU patients, there were no significant differences in Q values 
      as measured by TD (6.6 L/min), MIC (6.3 L/min), and NCCOM3 (6.4 L/min). Both MIC 
      and NCCOM3 Q values were comparable to TD in patients. In normals, however, the 
      NCCOM3 estimated larger values for Q than did the MIC (NCCOM3, 9.2 L/min; MIC, 
      6.2 L/min). Q values obtained with MIC in normals were comparable with published 
      values for supine normals. Thus, the two techniques agreed in the patients but 
      not in the normals. The reasons for these results are not obvious from the data, 
      but are attributable to the measurements by the NCCOM3. Because of this, caution 
      is suggested when interpreting absolute Q values obtained by the NCCOM3.
