Indicator Dilution Estimation of Capillary Endothelial Transport

Estimation of extravascular lung water by indicator-dilution techniques.

A compartmental capillary, convolution integration model to investigate nutrient transport and metabolism in vivo from paired indicator/nutrient dilution curves.

Thirty-three paired indicator/nutrient dilution curves across the mammary glands of four cows were obtained after rapid injection of para-aminohippuric acid (PAH) plus glucose into the external iliac artery. For the measurement of extracellular volume and kinetics of nutrient uptake from indicator dilution curves, several models of solute dispersion and disappearance have been proposed. The Cro...

Time and Concentration Components of Indicator-Dilution

T HE RECORDING of concentration-time curves at a peripheral arterial site following injection of an indicator into the heart and great vessels provides a valuable tool for the study of normal and abnormal circulation. Its increasing use in diagnostic and research laboratories attests to its efficacy. When this technic is used, it is desirable to have a normal standard of reference with which th...

Methodology of indicator dilution cardiac output determination.

Indicator-dilution studies with "diffusible" indicators.

• The indicator-dilution principle has been applied to studies of the circulation in order to provide estimates of flows and volumes in the vascular compartment. A sine qua non of validity of these estimates is that the indicator used remain within the confines of: the vascular compartment for the entire duration of the period required to obtain appropriate samples of blood. In such a symposium...
