Monitor and touch screen
Default alarm point
• Inlet pressure sensor:
–250 mmHg ± 30 mmHg
• Return pressure sensor:
+400 mmHg ± 37 mmHg
Pressure accuracy
± 6% of the sensor reading or ± 20 mmHg,
whichever is greater

RBC detector
Characteristics
Performance
Conditions
RBC detection level
> 1.5% hematocrit
• TPE procedures: System automatically
diverts fluid away from the remove bag
when it detects RBC.
• MNC collection procedures: System initiates
a collection phase when it detects RBC
exiting the chamber.
Table 18-17:
Low-level and high-level reservoir sensors
Characteristics
Performance
Conditions
Pump stroke volume between
sensors
• 49 mL ± 9 mL
• Sensors detect foam as air.
Level sensor requires a load force of > 5 lb
(2.3 kg) each (> 10 lb [4.5 kg] total).
Alarm occurrence
When fluid is not detected at the low-level
sensor, the system stops the pumps before air
enters the line.
System performs a duplicate (redundant)
safety check. If condition is not resolved after
a specific number of tries, operator must
disconnect patient.

Return line air detector
Characteristics
Performance
Conditions
Alarm occurrence
Alarm is generated if the system calculates
that the patient might have more than 1 mL of
air in circulation.

Conditions
Monitor with graphical user
interface (GUI) touch screen
• Monitor holds a touch screen that provides a
tactile operator interface.
• Monitor has a speaker for sounding
procedure and alarm tones, alarm lights,
and two external dedicated buttons with
icons (stop button and pause button).
Screen is touched to cause a change in
resistance.
Size
Measures 26.7 cm (10.5 in) diagonally
