SERIAL CARDIAC OUTPUT ESTIMATIONS DURING ANAESTHESIA WITH THE EVANS BLUE DYE DILUTION TECHNIQUE
Acta Anaesthesiologica Scandinavica, 1960SUMMARYThe 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, 1956One 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, 1976Using 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, 1958The 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.

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

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,

Blood flow determination in splenorenal shunts using a dye dilution technique.
Acta chirurgica Scandinavica, 1978Determination of flow through splenorenal shunts performed for portal hypertension was tried in 7 patients using a dye dilution technique. Varying shunt flows were obtained. The results of the flow determinations were compared with the findings at arteriography and the cause of the varying flows could be revealed.

Cardiovascular physiology in normal pregnancy: Studies with the dye dilution technique
American Journal of Obstetrics and Gynecology, 1954Abstract 1. 1. A new method for the determination of cardiac output and plasma volume in man based upon the Hamilton dilution principle has been presented. The method is simple, accurate, requires very little equipment, and can be applied clinically. Repeated determinations can be made on the same patient with no discomfort to the patient.

To determine whether the dye-dilution technique using aminohippurate sodium accurately measures amniotic fluid volume.Singleton pregnancies with intact membranes undergoing a Cesarean delivery had their amniotic fluid volume assessed by the dye-dilution technique and direct measurement.Fifteen women were prospectively assessed.

Compensatory Hyperplasia of the Human Kidney Evaluated by Angiography and a Dye Dilution Technique
Acta Radiologica. Diagnosis, 1980The renal blood flow and related variables were assessed with a dye dilution technique in conjunction with angiography of the enlarged kidney in 13 patients with unilateral disease, hypoplasia or aplasia of one kidney. The total renal blood flow, the width of the arteries, the kidney area, the vascular volume and the thickness of the cortex were all ...
