Comparative Study Observational StudyComparison of cardiac output estimates by bioreactance and inert gas rebreathing methods during cardiopulmonary exercise testing.
This study assessed the agreement between cardiac output estimated by inert gas rebreathing and bioreactance methods at rest and during exercise. ⋯ Bioreactance and inert gas rebreathing methods show acceptable levels of agreement for estimating cardiac output at higher levels of metabolic demand. However, they cannot be used interchangeably due to strong disparity in results at rest and low-to-moderate exercise intensity.
