“…By virtue of this small dead space and use of a closed sterile system, blood loss was estimated to be less than 1.0 ml per curve recorded. A study comprising 20 curves, therefore, would result in slightly more than a 5 % blood volume reduction in a newborn infant over a period of [1][2] hours. Previous studies have shown (16) that even sudden volume depletions of this magnitude are well tolerated without extreme hemodynamic effects.…”

SUMMARY Principles and techniques for the application of indicator‐dilution studies to the newborn period are discussed. A simple method for in vivo dye curve calibration is described, and a modification of the forward triangle factor for cardiac output estimation in this age group is presented: Methods of calculation of cardiac output and shunts are given. Many problems unique to the neonatal period are suited to study by careful application of these techniques.
