Function and Range
AC pump flow rate Changes to the AC pump flow rate do not change the inlet pump flow rate, but cause recalculation
of the inlet:AC ratio.
range: 1 to 12 mL/min.
Inlet pump flow rate Changes to the inlet pump flow rate do not change the AC pump flow rate, but cause recalculation
of the inlet:AC ratio.
range: up to 150 mL/min
For special recovery procedures, you can enter a minimum inlet pump flow rate of 0 (zero) to stop
the inlet pump. During Dual-Needle procedures, the maximum inlet pump flow rate is
150 mL/min or the inlet:AC ratio x 12, whichever is the smaller.
During Single-Needle ELP and LRS procedures, the maximum average inlet pump flow rate is
65 mL/min; during LRST procedures, it is 70; during Single-Needle TPE procedures, it is 60. The
maximum inlet pump flow rate for Single-Needle TPE procedures can be lower if necessary, to
prevent the instantaneous pump flow rate from exceeding 150 mL/min.
Plasma/RBC pump flow rate Changes to the plasma/RBC pump flow rate will affect the hematocrit in the RBC line as follows:
Range: 2 to150 mL/min •
•
During RBCX procedures, pressing PLASMA above the display changes the red blood cell flow out
of the centrifuge instead of the plasma flow.
Collect/replace pump flow rate Changes to the collect/replace pump flow rate will affect the cell concentration during collection
procedures and the fluid balance during TPE and RBCX procedures.
Range: 1 to 150 mL/min
Inlet:AC ratio Changes to the inlet:AC ratio will change the inlet pump flow rate only (inlet pump flow rate =
inlet:AC ratio x AC pump flow rate); the AC pump flow rate remains the same. Changes to the AC
Range: 3 to 50
pump flow rate or the inlet pump flow rate can cause an inlet:AC ratio change between 2 and 100.
Centrifuge speed The centrifuge speed can be changed in Manual mode.
Range: 400 to 2400 rpm
Description
Increased plasma pump flow rate = increased Hct in RBC line
Decreased plasma pump flow rate = decreased Hct in RBC line
