Does noninvasive measurement of cardiac output using partial CO2 rebreathing accurately estimate cardiac output compared to thermodilution?
Partial CO2 rebreathing provides a fully automated, noninvasive method for estimating cardiac output that correlates well with invasive thermodilution.
Capek et al. (1988) studied this question.
