Venous pressure (PV)
Electronically measured by a pressure sensor and digitally
displayed
Measurement range:
- 500 ÷ +500
mmHg
Allowed tolerance
± 10
mmHg
Working range:
+20 ÷ +50
mmHg
During Therapy:
Alarm limits:
-10 ÷ +250
mmHg
Default alarm window: Automatic control
Lower limit:
Reference value - 20
mmHg
Upper limit:
Reference value + 40
mmHg
Adjustable in parameter setting
The window limiting values are set 10 s after reaching the
set Blood Flow. The reference value slowly follows the
systematic pressure variation.
Protection system:
Double channel pressure monitoring with sensor test
during preparation phase.
Alarm override:
The absolute alarm limits cannot be overridden.
The alarm window can be overridden during Blood Flow
change/stop, Therapy start or PV level regulation till the
re-stabilization of PV pressure (10 s).
Acoustic alarm interval:
120
s
Safety air detector (SAD)
Ultrasonic sensor on the venous line below the venous air
chamber
Sensitivity:
0.1 ml air bolus or
2.0 ml air*
*Calculated integral volume of any air in the form of
micro-bubbles, micro-foam or the dropping of the air
level in the venous line below the sensor. It is decreased
continuously by a natural air removal rate.
Protection system:
Double channel air monitoring with sensor test during
preparation phase and automatic, cyclic test during
therapy.
Alarm override:
The alarm cannot be overridden during the therapy.
Acoustic alarm interval:
120
s
Safety air clamp (SAK)
Electromagnetic clamp behind the safety air detector to close
the venous return line
It is closed in case of a blood side alarm (e.g. by air detection).
Protection system:
Double channel activation with actuator test during
preparation phase.
