Abstract:
1. A process system comprising a separation device that, in use, performs a separation process including separation of red blood cells from blood or a suspension containing red blood cells, an outlet line coupled to the separation device at a selected location to allow intentional removal of substantial separated red blood cells from the separation device, at least in part, while the separation process occurs, a sensor associated with the outlet line to sense hematocrit of red blood cells removed from the separation device and to generate a sensed hematocrit output, and a controller including an application control manager coupled to the separation device and programmed to deliberately remove red blood cells from the separation device through the outlet line at a targeted red blood cell removal rate that is greater than zero by controlling removal of red blood cells from the separation device based, at least in part, upon the sensed hematocrit output.
