Thermodilution via pulmonary artery catheter may support reliable cardiac output assessment; leaves open prospective validation in broader clinical cohorts.
Does the thermodilution technique using a pulmonary artery catheter accurately and reproducibly measure cardiac output compared to the dye dilution technique?
Thermodilution using a pulmonary artery catheter is a highly precise and reproducible method for measuring cardiac output that correlates strongly with the dye dilution technique.
Olsson et al. (2008) studied this question.
