Caution against relying on pulse dye densitometry for cardiac output in CABG patients; Level 4 data leave open technique refinements.
Does pulse dye densitometry accurately measure cardiac output compared to bolus thermodilution in patients undergoing elective coronary artery bypass grafting?
Pulse dye densitometry is inaccurate for measuring cardiac output in anesthetized patients before CABG and unusable postoperatively due to low signal amplitudes.
Baulig et al. (2005) studied this question.
