Correlations support fiberoptic stroke index validity in catheterization; leaves open routine adoption without prospective validation.
Does the fiberoptic-dye dilution method accurately measure cardiac output compared to the Fick method and angiocardiography in patients undergoing cardiac catheterization?
The fiberoptic-indicator dilution method provides an accurate measurement of cardiac output during cardiac catheterization without the need for blood withdrawal.
