Chapter 6: Special Cycles
Description
Several processing cycles are available to facilitate operating the X
TRA
system during special
circumstances:
• Return - the Return cycle allows the operator to return blood from the bowl back to the reservoir.
• Concentrate - the Concentrate cycle (“Conc”) allows the bowl to be filled from the RBC bag
(rather than the reservoir).
• Prime IV - the Prime IV cycle allows the RBC bag and empty line to be primed with saline wash
solution.
• Purge - the Purge cycle allows the operator to purge air from the RBC bag.
As Table 6-1 shows, not all special cycles are available with all processing protocols: YES means the
cycle is available under that protocol; NO means the cycle is not available.
Enabling Purge and Prime IV Special Cycles
The “Purge” and “Prime IV” features must be enabled in the Features tab of the Configuration Mode
Screen before they will be available for use. Refer to “How to Enter the Configuration Mode” on page
8-2 for instructions on entering the Configuration Mode Screen. For more on configuring the X
TRA
system refer to the rest of
Chapter 8: Configuring Xtra
.
The Special Cycles Screen
Touching the “Special” button from the Ready Screen displays the Special Cycles Screen
which allows independent access to the Return, Concentrate, Prime IV, and Purge cycles via
the buttons in the button bar (see Figure 6-1).
