title: Non-invasive cardiac output monitor validation study in pediatric cardiac surgery patients.
abstract: OBJECTIVE
  To validate a non-invasive cardiac output monitor in pediatric cardiac surgery patients.
  
  
  METHODS
  Prospective trial.
  
  
  METHODS
  Operating room.
  
  
  METHODS
  20 pediatric cardiac surgery patients ASA physical status 3 and 4.
  
  
  METHODS
  Aesculon noninvasive cardiac output monitor was used and compared to the cardiac output derived from the Fick equation. Oxygen consumption was measured and blood samples were taken from the arterial line and from the superior and inferior vena cava.
  
  
  METHODS
  Noninvasive cardiac output and cardiac index and Fick cardiac output and cardiac index. Oxygen consumption was measured by the TreyMed metabolic monitor. Blood samples were simultaneously drawn from the arterial line and from the superior and inferior vena cava purse string sites by the surgeon, prior to commencing cardiopulmonary bypass. Another data set was obtained right after termination of cardiopulmonary bypass.
  
  
  RESULTS
  There was a direct, significant relationship between Fick CO/CI and NICOM CO/CI measurements. More dispersion is detected when the magnitude of the measure increases, i.e., for older and larger patients.
  
  
  CONCLUSIONS
  There is a strong correlation between the cardiac output values derived from the Fick equation and the Aesculon non-invasive cardiac output monitor.
