A BLOOD PROCESSING SYSTEMS AND METHODS WHICH OPTICALLY MONITOR INCREMENTAL PLATELET VOLUMES IN A PLASMA CONSTITUENT

摘要

Blood processing systems and methods separate blood into constituents including a plasma constituent that includes a platelet volume. The systems and methods detect the optical density of the plasma constituent and generate a first output indicative of the optical density. A processing element integrates the first output relative to the volume of plasma constituent and generates an integrated output. The integrated output correlates to the platelet volume. A second processing element (324) generates an output based, at least in part, upon the integrated output, which depicts a value indicating a blood volume that needs to be processed to obtain a desired platelet volume.
