Operation Manual
DualFlow automatically determines the individual volumes of Contrast and Saline and the individual flow
rates needed for the Contrast and Saline portions of the DualFlow phase.
For example, if the user enters a total Flow Rate of 4.0 mL/sec and a total Volume of 60 mL, the individual
volume and flow rate of Contrast and Saline for the DualFlow phase would be as follows (based on the
sample percentages of Contrast):
Sample Ratio
A90% B10%
A80% B20%
A75% B25%
A70% B30%
A65% B35%
A60% B40%
A50% B50%
NOTE: To change the ratio once the phase has been programmed, re-select the phase and enter the new
ratio values per step 3.
