Thermal-dilution technics.
• .All thennal methods for the study of the circulation depend upon the induction of a change in the heat content of! the blood stream. As a result of the change, a particular time-dependent spatial distribution of temperature is developed in the blood according to the manner in which the change is brought about and as a function of the prevailing pattern of blood flow. In a general sense, any ...
متن کاملSpeculations concerning present and future developments in indicator-dilution technics.
• Speculations to be of appreciable value should be based on (1) thorough knowledge of the past and (2) as realistic as possible prediction of the needs of the future. Then from a knowledge of these two factors, perhaps an educated guess can be made as to how the developments and capabilities from the past up to the present may be extended and synthesized with the needs of the future in order t...
متن کاملDiagnostic applications of indicator-dilution technics in congenital heart disease.
Introduction • The diagnostic use of indicator-dilution technics in the study of congenital heart disease dates, for practical purposes, from 1950 with the nearly simultaneous description of methods for continuous recording of the concentration of Evans blue dye from Johns Hopkins University and from the Mayo Clinic." The diagnostic applications of indicatoi'-dilution technics have been intensi...
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 کاملThermal dilution curves in the intact animal.
The acceptance of thermal dilution curves for the estimation of cardiac output has boon discouraged by unconvincing comparisons with the Fick method and by the possibility of the loss of "indicator" to the tissues of the central circulation. The present studies were undertaken to examine the technical and physiologic factors affecting thermal curves, with particular reference to tissue heat exc...
