Corrected acetylene rebreathing matches dye dilution with low error in healthy subjects; leaves open validation for clinical use.
Does a modified acetylene rebreathing method accurately measure cardiac output compared to the dye dilution method in healthy subjects?
The modified acetylene rebreathing method, when corrected for arteriovenous shunt effects, provides a valid non-invasive measurement of cardiac output at rest and during heavy exercise.
Nyström et al. (1986) studied this question.
