Cardiac output measurements determined by dye dilution, iced-injectate thermodilution and room temperature thermodilution were compared in man in order to assess the random error of each method and to examine the systematic error of both thermodilution methods in comparison with dye dilution. Results showed that random error was greatest with room temperature thermodilution and least using iced thermodilution. Iced thermodilution correlated well with dye dilution, tending to overestimate cardiac output only at low flows. Room temperature thermodilution, however, overestimated cardiac output by up to 25% in the clinically important range and more so at low cardiac output.
为了评估每种方法的随机误差，并检验两种热稀释法与染料稀释法相比的系统误差，对人体通过染料稀释法、冷注射热稀释法和室温热稀释法测定的心输出量进行了比较。结果表明，室温热稀释法的随机误差最大，冷热稀释法的随机误差最小。冷热稀释法与染料稀释法相关性良好，仅在低流量时倾向于高估心输出量。然而，在临床重要范围内，室温热稀释法高估心输出量高达25%，在低心输出量时更是如此。
