ABSTRACT:
A multi-point method of determining a time-zero blood volume by the tracer dilution technique. A tracer is injected into the blood stream of a living being, and a plurality of mixed samples of blood and tracer are removed from the blood stream at a corresponding plurality of measured time intervals subsequent to the injecting step. A blood portion volume corresponding to each time interval is automatically determined from the tracer level in the mixed samples, and a time-zero blood portion volume is automatically calculated from the determined blood portion volumes and time intervals.
