Measurement of Extravascular Renal Water by the Thermal Dye Indicator Dilution Technique

Journal of Urology, 1982
Simple mechanical swelling of the renal parenchyma against an unyielding renal capsule may be responsible in part for the development of oliguria and acute tubular necrosis. However, until now, renal swelling was difficult to measure, except by postmortem gravimetric techniques.

Measurement of Flow Components on Upland Areas Using Dye Dilution Techniques

Transactions of the ASAE, 1988
ABSTRACT DYE dilution techniques can be used to measure rill, interrill, and interrill-to-rill flow rates on upland areas. Procedures and equations for making flow measurements are described along with equations for estimating interrill length and width.

Arteriovenous Shunting in Carcinomas Evaluated by a Dye Dilution Technique

Scandinavian Journal of Urology and Nephrology, 1977
In 19 patients with renal carcinomas determination of the renal blood flow and related parameters were determined. In 10 of the kidneys the renal blood flow was higher than 1700 ml/min, in five kidneys the vascular volume was increased and in all kidneys the appearance time of dye in the renal vein was below normal.

Blood Flow in Renal Carcinomas Evaluated by a Dye Dilution Technique and Angiography

Scandinavian Journal of Urology and Nephrology, 1977
In 31 patients with renal carcinoma referred for angiography, rapid sequence angiography was performed in 25. In 18 of the patients determination of renal blood flow and related parameters was made in conjunction with the angiography. Carcinomas with high and medium-high differentiation comprised Group I, while those with medium and poor ...

SERIAL CARDIAC OUTPUT ESTIMATIONS DURING ANAESTHESIA WITH THE EVANS BLUE DYE DILUTION TECHNIQUE

Acta Anaesthesiologica Scandinavica, 1960
SUMMARYThe limitations of Evans blue as the indicator in dye dilution studies of cardiac output were discussed. In practice serial output determinations were restricted to four in our hands.Low cardiac outputs were raised after induction of anaesthesia with halothane and high outputs were lowered.

CARDIAC OUTPUT BY THE DYE DILUTION TECHNIQUE UNDER THIOPENTAL SODIUM-OXYGEN AND EHTER ANESTHESIA

Survey of Anesthesiology, 1956
One hundred-twenty determinations of cardiac output by the dye dilution technic utilizing the cuvette oximeter were made on 20 dogs. Of these, 60 were done under thiopental sodium-oxygen analgesia and 60 were done after supplementing with ether. Arterial blood pressure was recorded by strain gauge.

Spontaneous Portorenal Shunting in Portal Hypertension Assessed by a Dye Dilution Technique

Acta Radiologica. Diagnosis, 1976
Using a dye dilution technique, blood flow was measured in the right and left renal veins in 12 patients with portal hypertension. There was evidence of spontaneous shunts to the left renal vein in all cases and at least in 4 cases to the right one.

Theory of measurement of blood flow by dye dilution technique

IRE Transactions on Medical Electronics, 1958
The general mathematical theory of measurement of blood flow by dye dilution techniques is discussed. The mathematical procedure for handling the recirculation problem is described, and it is shown that, in general, sampling of concentration at a single point is not sufficient to uniquely determine both the volume and flow in a vascular bed.

Comparison of dye dilution method to radionuclide techniques for cardiac output determination in dogs

Journal of Pharmaceutical Sciences, 1980
A study was undertaken to identify the most accurate 99mTc-labeled radiopharmaceutical and to determine the accuracy of a noninvasive radionuclide technique (antecubital injection and precordial detection) for cardiac output determinations. Phase I employed sodium pertechnetate, stannous pyrophosphate with sodium pertechnetate, technetium-99m red blood

Measurement of extravascular lung water by thermal-dye dilution technique: Mechanisms of cardiac output dependence

Intensive Care Medicine, 1990
The extent to which extravascular lung water (EVLW) is dependent on cardiac output was analysed in anaesthetized and mechanically ventilated pigs. EVLW was measured by thermal-dye dilution technique, by a fibreoptic thermistor catheter system (system 1), and by a thermistor catheter-external optical cuvette system (system 2). During baseline conditions,
