May support thermal over dye dilution due to lower calibration error; leaves open randomized outcome trials in cardiothoracic patients.
Does thermal dilution provide comparable accuracy and reliability to dye dilution for measuring cardiac output in cardiothoracic surgical patients?
Thermal dilution is clinically reliable and preferable to dye dilution for measuring cardiac output in cardiothoracic surgical patients due to its ease of use and lower calibration error.
Fischer et al. (1978) studied this question.
