A simplified method for calculation of the leftto-right shunt from a single earpiece dye-dilution curve.
In a preceding paper of ours,1 it has been reported that the estimation of shunt magnitudes can be done by using a single earpiece dye-dilution curve with some correction of the build-up time in infants and children with the left-to-right shunt. The present report describes a new, simplified method devised for the calcula tion of the shunt values using a single earpiece dye-dilution curve, beca...
متن کاملEarpiece dye-dilution technics for estimation of the left-to-right shunt in infants and children.
The infants and children subjected to this study consisted of 21 cases with ventricular septal defect, 9 cases with atrial septal defect, 3 cases with patent ductus arteriosus, one case with partial anomalous pulmonary venous return and 3 cases with the innocent murmurs (cf. Tables 1 and 2). The right-heart catheterization was performed in all the cases according to the conventional Fick proced...
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 کاملA simplified method for quantitating left-to-right shunts from arterial dilution curves.
This report presents a new, simple and reliable method of quantitating left-to-right shunts from arterial dilution surves. When indicatior (e,g., indocyanine green) is injected centrally (right venticle or pulmonary artery) and blood is withdrawn rapidly from either the aorta or other central systemic artery, in the presence of a left-to-right shunt to recorded indicator-dilution curve usually ...
