Dye dilution curves and cardiac output in newborn infants.
The pattern of ldye dilution curves and the cardiac output was studied in 29 healthy newborn infants during the first 26 hours of life by the method of Wood and his associates. Thirty-six per cent of all infants studied had curves of normal contour which occurred mostly in infants older than 15 hours. Infants younger than 15 hours tended to have curves of abnormal shape. These were either di-ph...
متن کاملOn-line computation of cardiac output from dye dilution curves.
• Calculation of cardiac output from dye dilution curves as described by Hamilton has been well verified.' 3 The technique of calculating the cardiac output with the use of a planimeter or replotting on log paper is tedious and-often inexact. Furthermore, the necessary long delay between the dye injection and the availability of the result has limited the use of this technique in medical resear...
متن کاملFiberoptic-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 کاملLack of agreement between bioimpedance and continuous thermodilution measurement of cardiac output in intensive care unit patients
BACKGROUND: Bolus thermodilution is the standard bedside method of cardiac output measurement in the intensive care unit (ICU). The Baxter Vigilance monitor uses a modified thermodilution pulmonary artery catheter with a thermal filament to give a continuous read-out of cardiac output. This has been shown to correlate very well with both the 'gold standard' dye dilution method and the bolus the...
متن کاملComparison of central and peripheral injection sites in the estimation of cardiac output by dye dilution curves.
• In the measurement of cardiac output by indicator dilution methods, the indicator may be introduced either centrally or peripherally. It is clear that use of a peripheral vein, particularly in large animals such as man, may result in two major sources of error, a) Indicator may be trapped between the injection site and the central circulation resulting in a small primary curve and an overesti...
