Touching the Pause button will stop the pump rotor. The centrifuge will continue to
spin for five minutes. While the system is paused, the operator may use the Phase
buttons in the button bar to abort the Concentrate cycle and continue processing in
the selected (or a different) phase. In the preoperative sequestration protocols, the Concentrate cycle
is aborted by touching the “Conc” button a second time while processing is paused. To resume the
paused Concentrate cycle, touch the Play button.
When the buffy coat is detected, exit from the Concentrate cycle comes about in the same way as in
the Fill or Spill phases, according to the active operating mode and protocol (refer to “Running a Case
With the X
TRA
System” on page 5-5 and “Running a Preoperative Sequestration Case” on page 10-9).
Dealing With Expected Warnings During a Cycle
This section describes the most likely warnings, along with the appropriate response to each, which
can be triggered during a preoperative sequestration processing cycle. For a complete description
warnings and alarms, refer to
Chapter 14: Troubleshooting
.
Whole Blood Bag Empty
The Whole Blood Bag Empty alarm is triggered during the Fill phase if air is detected in the line
between the whole blood bag and the centrifuge bowl. Also refer to “Whole blood bag empty.” on page
14-22.
When triggered, the acoustic sequence is sounded (if enabled), the message “Whole blood bag
empty.” is displayed in the message area of the current screen, the processing displet is highlighted
with a yellow outline, and the processing cycle is paused.
The operator can proceed in different ways, depending on the following conditions:
• If blood is still present in the whole blood bag:
a. Check that the connections are properly sealed and eliminate possible occlusions along the fill
line.
b. Check that the tube going to the bowl is fully down in the air detector seat.
c. Touch the Play button to continue.
Should the message persist, please contact LivaNova Technical Services.
• If the whole blood bag is empty and there is an additional whole blood bag available:
a. Remove the empty bag and connect the new whole blood bag.
b. Touch the Play button to continue.
• If the whole blood bag is empty and no more whole blood is available:
a. If the RBC bag contains enough fluid:
• Touch the “Conc” button to complete the bowl filling by pumping the contents of
the RBC bag into the bowl according to the Concentrate function (refer to “The
Concentrate Cycle (With the PPP/PRP Protocols)” on page 10-16).
b. If the RBC bag is empty:
• Touch the “Empty” button to transfer the remaining contents of the bowl into the
RBC bag.
Touch the Mute button (located at the far left of the button bar) to silence the alarm for 45
seconds.
