Abstract
This invention provides a method for controlling a fluid separation system, preferably a blood apheresis system having a leukocyte reduction chamber. The method utilizes a return-flow alarm system. A return-flow alarm-triggering pressure is specified, and when pressure of the return flow in the system is higher than or equal to the specified pressure, a return-flow alarm is triggered.
