Abstract
A method for obtaining integral data of the dilution curve obtained when an indicator is injected into a closed system containing a circulating fluid, and as particularly adapted for utilization in blood flow analysis computers. The apparatus is constructed to analyze the characteristic concentration curve in an abbreviated time period to establish the full integral value of the curve. Concentration curve input is integrated through circuitry which detects relative curve change through a Phase I for subsequent summation with a data value summation through a selected portion of the exponential decay curve, that portion identified as Phase II, thereby to predict the remainder of the curve area and provide data output of an integral value for the entire concentration curve above a designated zero or set point level.
