Does a new generation continuous-wave transesophageal Doppler device accurately measure cardiac output compared to thermodilution in patients early after coronary artery bypass surgery?
The second-generation transesophageal Doppler device provides acceptable reliability for monitoring relative cardiac output trends, but not absolute values, in sedated, paralyzed patients after CABG.
Schmid et al. (1993) studied this question.
