Abstract
Apparatus, system and method are provided for controlling flow through a biological fluid processing device. Pressure of fluid flow through a flow path is monitored and flow rate in the flow path is increased or decreased based on sensed pressure levels for selected periods of time. This has particular application in controlling flow in an infusion or return flow path of an apheresis device that separates whole blood into one or more blood components.
