The use of invasive techniques, angiography and indicator dilution, for quantification of valvular regurgitations [PDF]

European Heart Journal, 1987
Angiographic techniques have been used for the quantification of mitral or aortic and rarely tricuspid regurgitation. Mitral or aortic regurgitant volume per beat and the regurgitation fraction (fao and fm, respectively) are obtained from the angiographic determination of total left ventricular stroke volume (TSV) and forward stroke volume (FSV ...

Reliability of cerebral blood flow measurements by transcerebral double-indicator dilution technique

European Journal of Anaesthesiology, 2001
The recently developed transcerebral double-indicator dilution technique has proven to be a feasible monitoring alternative to measure global cerebral blood flow at the bedside. However, the short-term repeatability of transcerebral double-indicator dilution measurements has not yet been investigated.

DEFINITION OF MIXING RATE OF INDICATOR BY INDICATOR DILUTION METHOD: EVALUATION OF RELATIONSHIP BETWEEN MIXING RATE OF INDICATOR AND CARDIAC OUTPUT DETERMINATION [PDF]

, 1986
It is generally agreed that complete mixing of the indicator is one of the most important factors of the indicator dilution method, however, no clear definition of the mixing state has been established. We established a formula for the mixing rate of the

A prospective study to evaluate the accuracy of pulse power analysis to monitor cardiac output in critically ill patients [PDF]

, 2008
Background Intermittent measurement of cardiac output may be performed using a lithium dilution technique (LiDCO). This can then be used to calibrate a pulse power algorithm of the arterial waveform which provides a continuous estimate of this variable ...

Peritoneal dialysate volume determined by indicator dilution measurements [PDF]

, 1988
Peritoneal dialysate volume determined by indicator dilution measurements. Dialysate volume was simultaneously determined by two different indicator dilution techniques as a function of dwell time in a rabbit model of peritoneal dialysis using isotonic ...

Measurement of Solute Transport in the Endothelial Glycocalyx Using Indicator Dilution Techniques [PDF]

Annals of Biomedical Engineering, 2009
A new method is presented to quantify changes in permeability of the endothelial glycocalyx to small solutes and fluid flow using techniques of indicator dilution. Following infusion of a bolus of fluorescent solutes (either FITC or FITC conjugated Dextran70) into the rat mesenteric circulation, its transient dispersion through post-capillary venules ...

Estimation of Ventricular Volumes by a Constant Infusion Indicator Dilution Technique [PDF]

Circulation Research, 1964
A constant infusion indicator dilution method for estimating ventricular volumes is introduced and its feasibility demonstrated. Using this method, volumes can be calculated by two different approaches, one of which does not assume effective distribution of indicator throughout end diastolic volume ( EDV ).
