TI  - Noninvasive assessment of cardiac output by impedance cardiography in the newborn 
      canine.
PG  - 63-5
AB  - Currently, critical care monitoring of cardiac function in the newborn human 
      consists mainly of measuring heart rate and BP. A noninvasive technique for 
      assessing cardiac output routinely in the critically ill neonate would facilitate 
      clinical management. Impedance cardiography (IC) is a noninvasive technique which 
      measures stroke volume on a beat-by-beat basis. This study compared cardiac 
      output as measured by thermodilution (TD) to that measured by IC in seven canine 
      pups 6 to 7 days old weighing 0.66 to 0.86 kg. Cardiac output was altered by the 
      withdrawal and reinfusion of blood. There were no significant differences between 
      the two methods for either the absolute value of cardiac output (r = .96) or the 
      percent change in cardiac output (r = .97). Coefficients of variation were 3.0% 
      for TD and 3.6% for IC. These results indicate that IC can be used to assess 
      serially cardiac function in the newborn.
