Abstract
Systems and methods for controlling fluid flow during a fluid exchange procedure. In one aspect, a system is provided for controlling a net fluid volume difference of a patient during and/or after a fluid exchange procedure. The system comprises a first flow path for flowing at least a first fluid from the patient and a second flow path for flowing at least a second fluid to the patient. First and second reservoirs are respectively associated with the first and second flow paths. A controller is associated with the first and second flow paths for controlling first and second flow rates and operable to determine an actual flow rate for each first and second fluid and to change a first or second flow rate in response to a difference between at least one of such flow rates and its respective actual flow rate.
