This chapter explains how to operate the Cell Saver (CS5+) System in the
MANUAL mode.
Though not recommended, it is possible to process blood manually in the CS5+.
Given the processing capabilities of the CS5+, manual processing is unnecessary.
The steps involved in manual processing during autotransfusion are outlined
below.
In order to place the system into the MANUAL mode of operation, press the
MODE key on the control panel
Note: When in the manual mode, it is the responsibility of the operator to
advance the system from one function to the next. The air detector is enabled in
MANUAL EMPTY AND MANUAL RETURN and THE WASTE BAG WEIGHER IS
ENABLED IN MANUAL FILL, MANUAL WASH AND MANUAL CONC, but
otherwise, all sensing devices are disabled in the manual mode (including BOWL
OPTICS sensor and the effluent line sensor).
Once the machine has advanced into the FILL mode, it will remain there
indefinitely until the operator initiates a change. The MANUAL mode allows the
operator to reverse the process cycle, or skip entire functions. Examples of such
maneuvers would be as follows: 1) to go from WASH to FILL; 2) to go directly
from FILL to EMPTY.
After the centrifuge bowl has been stopped, the red cell separation is lost. This
settling of cells could lead to a red cell spillage if, when restarting, fluid is
pumped into the bowl before the cells are allowed to separate once again.
When processing is RESUMED in the AUTOMATIC mode, there is a “recentrifuge
delay” which allows the centrifuge a few moments to attain separation before
starting to pump more fluid into the bowl. The recentrifugation delay can be
overridden in the MANUAL mode by pressing the START key a second time after
the recentrifuge delay has been on for 15 seconds. If the operator chooses to
override the delay, the operator must be aware of the possibility of cell spillage
caused by pumping fluid into a bowl with poor or no separation.
To avoid a cell spillage, the operator must press the PUMP PAUSE control.
Pressing PUMP PAUSE again will cause the pump to resume at the previous rate.
Or to adjust pump speeds, use the PUMP SLEW keys to gradually change the
pump speed until the desired speed is reached while observing that the cells have
time to separate.
Warning: In the manual mode all mode changes and advances must be initiated
by the operator.
Unlike the sensing devices, all cumulative Volume Accounting Functions
(Volume Processed, Volume Returned, and Wash Monitor) are operative during
manual operation.
