Studies of coronary blood flow by multiple dye dilution curves.
The indicator-dilution technique has recently been applied to the study of the coronary circulation. One of the methods which have been proposed is the estimation of coronary blood flow from dilution curves sampled from the right ventricle after the injection of radio-iodinated human serum albumin into the left ventricle or into a catheter "wedged" in a branch of the pulmonary artery (1). Anoth...
متن کاملEffect of coronary blood flow on radioiosotope dilution curves measured by precordial scintillation detection.
IN a comparison of radioactive bolus dilution curves obtained simultaneously by external monitoring' over the preeordium and by sampling from a peripheral artery, it was noted that arterial curves had a more rapid disappearance rate than precordial curves. This observation, made originally in human subjects, led to an investigation in animals designed to determine the reason for the distortion ...
متن کاملIntrarenal distribution of blood flow in man. A new analytical method for dye-dilution curves.
To measure blood flow through fast and slow pathways of the kidney separately, a new method of analyzing dye-dilution curves was devised. Twenty-five patients with hypertension or renal disease were selected for study. Indocyanine green was injected into one renal artery and dye-dilution curves were recorded in blood from the ipsilateral renal vein, using a densitometer. Recirculation effect wa...
متن کاملDetection of bronchial blood flow from earpiece dye-dilution curve.
In an attempt to detect an increased bronchial blood flow in man from the earpiece dye-dilution curve, the reliability of three indexes was investigated by comparing them with the values of bronchial blood flow measured from the left atrial dye-dilution curve following dye injection into the aortic root. The first index is obtained from the Cp method, in which the ratio of the peak concentratio...
متن کاملAssessment of mitral regurgitation by dye dilution curves.
Hering (1829, 1832) obtained circulation times by detecting injected samples of potassium ferrocyanide by the Prussian Blue reaction, as quoted by Dow (1956). Stewart (1894) extended the work of Hering and was able to measure the cardiac output by a quantitative determination of the dilution of a solution of salt injected intravenously. It has taken many years since Stewart's time for the indic...
