system are provided in the remaining chapters of this manual.
Important Notes
The unit displays numeric values and percentages, which are to be interpreted as follows:
• Centrifuge Speed (RPM): The displayed value is the target value set by the user. Once processing
is started, the centrifuge accelerates to this set value according to system procedures.
• Pump Flow Rate (ml/min.): As stated above, the displayed value is the target value set by the
user. In this case, the real flow-rate value is also affected by the tolerances of the disposable
tubing and other variability factors.
• Vacuum pressure (mmHg): The datum visualized is the setpoint set by the user.
• Volumes transferred (mL): The volumes transferred are calculated based on the effective pump
speed, although there is always a margin of error due to the variability of the capacity/speed ratio
and the piping tolerance. However, these values must not be considered measured values, but
only reference values for the user.
• Hematocrit indication (%): The hematocrit value is detected and measured on the basis of the
blood flowing through the section of tube inserted into the hematocrit indicator. To prevent the
provided indications from varying with the temperature, the current Bowl Set, and other ambient
conditions, a preliminary calibration of the indicator is carried out with saline solution during the
set-up phase, before blood processing starts.
• Supernatant removal indicator (%): it is an algorithm representing the percentage of supernatant
that has been removed, and more specifically, the percentage of supernatant that has been
replaced by saline solution during the Wash phase.
• Waste line color indicator (color): it indicates the residual concentration of waste products in the
fluid exiting from the bowl, measured on the basis of the color detected on the outlet line of the
bowl (waste line).
CAUTION
If the display shows incomprehensible and erroneous messages or messages
different from those indicated in this manual, immediately stop the unit and
contact LivaNova Technical Service.
