Fiberoptic-Dye Dilution Method for Measurement of Cardiac Output
A new method for the measurement of cardiac output has been tested in 69 patients undergoing catheterization of the right and left sides of the heart. It is based on the recently described fiberoptic hemoreflection method. In order to verify the validity of these measurements, correlations with stroke indices determined by the Fick principle and by biplane angiocardiography were also carried ou...
متن کاملThermal dilution measurement of pulmonary and systemic blood flow in secundum atrial septal defect, and transposition of great arteries with intact interventricular septum.
The measurement of cardiac output is difficult in infants and children. In them the Fick and dye dilution methods both have distinct disadvantages. The Fick method requires cumbersome equipment, especially for measuring oxygen uptake. The dye dilution method requires the injection of a dye and the placement of an arterial catheter to sample large quantities of blood rapidly; furthermore, it is ...
متن کاملAutomated non-invasive measurement of cardiac output by the carbon dioxide rebreathing method: comparisons with dye dilution and thermodilution.
The accuracy and reproducibility of indirect measurement of cardiac output at rest by the carbon dioxide rebreathing (indirect Fick) method with an automated respiratory analysis system (Gould 9000IV) were compared with simultaneous measurements made in duplicate by dye dilution and thermodilution in 25 patients having cardiac catheterisation studies. Measurements of cardiac output by the carbo...
متن کاملMeasurement of stroke volume by the vibrocardiogram.
An examination has been made of the relationship between stroke volume measured by dye dilution and left ventricular isovolumetric contraction and ejection times as measured by the vibrocardiogram. These studies were performed in 10 normal subjects under postural alterations, and in 11 patients recovering from acute myocardial infarction. gression analyses of the data showed that ejection t h e...
متن کاملIndicator-dilution measurement of cardiac output with dissolved hydrogen.
Dissolved HL has been used as an indicator for measuring cardiac output by the techniques of constant-rate injection and sudden, single injection indicator dilution. Because of its low solubility, H2 is eliminated essentially quantitatively in the lungs and recirculates negligibly. The constant-rate injection technique involves the gas chromatographic measurement of pulmonary (or systemic) arte...
