ABSTRACT:
Using the principle of pulse oximetry, the relationship between the logarithm of dye density and the passage of time is obtained to determine a regression line for the linear portion of the relationship; an intial dye density in the blood is determined for the point of time that defines the mean transit time for the initial circulation of the injected dye on the regression line; and the circulating blood volume is calculated from the thus determined initial dye density.
