Red Blood Cell Exchange (RBCX) Procedures
Entering and Confirming Run Values
Enter the run targets listed below, according to the type of RBCX procedure you selected. Table 9-3 contains
descriptions of the run targets that appear on the run values screens. Then review the run values and make any
changes necessary to achieve your run targets. A black frame appears around the button of the primary run target.

Table 9-3:
Descriptions of run targets for RBCX procedures
Run Target
Description
FCR (%)
Fraction of cells remaining. Target percentage of starting defective RBC that will remain in
the patient’s blood at the end of the procedure. (Target defective RBC (%)/starting
defective RBC (%) = FCR.)
After you enter an FCR for an exchange procedure, the system calculates and displays the
volume of replacement fluid that is required to complete the procedure.
Note:
You may enter the starting and target defective RBC instead of the FCR, and the
system will calculate and display the FCR. To do this, touch the button for FCR on the screen
and then touch
FCR
on the data entry pad. The blood drop icon (
) appears on the data
entry pad to allow you to enter the values for defective RBC.
• Starting defective RBC (%)
Percentage of defective RBC in the patient’s blood at the start of the procedure
• Target defective RBC (%)
Percentage of defective RBC in the patient’s blood at the end of the procedure
Minimum Hct (%)
Lowest patient Hct during the procedure
Target Hct (%)
Desired patient Hct at the end of the procedure
Replaced (mL): Exchange
Volume of replacement fluid that is required to complete the exchange procedure. If you
enter a volume here, the system calculates and displays the FCR.
