TI  - Continuous Fick cardiac output compared to thermodilution cardiac output.
PG  - 881-5
AB  - A system has been developed to monitor continuously the components of the oxygen 
      Fick equation: oxygen consumption by a gas exchange analyzer and arteriovenous 
      oxygen difference by pulse and fiberoptic oximetry. A computer-based system was 
      developed which calculates cardiac output and other variables every 20 sec. 
      Continuous Fick (CF) cardiac output was compared to thermodilution (TD) cardiac 
      output in 21 ventilated post-cardiac surgery patients. A total of 237 
      simultaneous cardiac output measurements had a range between 2 and 11 L/min. The 
      correlation between CF and TD cardiac outputs was r = .86, with an equation of TD 
      cardiac output = 0.92 CF cardiac output + 1.16. There was a significant (p less 
      than .001) difference between the two methods of cardiac output estimation. The 
      CF method was consistently lower than TD; this difference was greater at lower 
      flows. CF cardiac output measurement is practical; it offers distinct advantages 
      in viewing cardiac output together with oxygen demand and oxygen extraction.
