PROBLEM TO BE SOLVED: To provide fluid pump control modes in a medical perfusion system. SOLUTION: The fluid pump control modes include a Back Off Response Mode, a Flow Servo Mode, a Pressure Servo Mode, and a Master-Slave Servo Mode. In the Back Off Response Mode, the pump's speed is decremented (1906) to a new speed when an alarm condition is detected. In the Flow Servo Mode, a pump's speed is controlled to maintain a fluid flow rate indicated by a user as a setpoint. In the Pressure Servo Mode, a pump's speed is controlled to maintain a pressure set by the user. In the Master-Slave Servo Mode, a slave pump is controlled based upon the sensed speed of the master pump. COPYRIGHT: (C)2011,JPO&INPIT
