Transoesophageal Doppler cardiac output measurement was evaluated against the thermodilution method in eleven patients undergoing elective cardiac surgery. A total of 106 pairs of Doppler and thermodilution values were obtained. Cardiac output was measured over a range of 2.3 l.min-1. to 11.51 l.min-1. The mean difference between the Doppler and thermodilution measures was -1.0 l.min-1 (thermodilution minus Doppler). Standard deviction was 1.8 l.min-1. This is a significant difference. It is concluded that these techniques do not agree when measuring cardiac outputs.
在11例接受择期心脏手术的患者中，对经食管多普勒心输出量测量法与热稀释法进行了评估。共获得106对多普勒测量值和热稀释测量值。心输出量测量范围为2.3升/分钟至11.51升/分钟。多普勒测量值与热稀释测量值之间的平均差值为-1.0升/分钟（热稀释值减去多普勒值）。标准差为1.8升/分钟。这是一个显著差异。结论是，在测量心输出量时，这些技术的结果不一致。
