HCEN12745 Revision 10.2016
Program version 2.xx
AK 98 Dialysis Machine - Alarms B:37
120 Low venous pressure
120 Low venous pressureī¼
Appears:
When the patientās venous pressure reaches the set low
alarm limit. The venous pressure is the resistance of the
blood returning to a patient.
Machine actions:
ā The blood pump stops.
ā The venous blood line clamp closes.
ā Ultrafiltration rate is set to zero.
During single needle treatment the alarm is delayed for 3
seconds, to avoid false alarms since the venous pressure
limits are used for single needle phase shift.
Operator action:
1. Stop the blood pump. The arterial and venous pressure
alarm limits are automatically widened.
2. Check that the venous blood line is properly attached to
the dialyzer.
3. Check that the venous needle is in proper position.
4. Check that there are no clots before or in the dialyzer.
5. Adjust the blood flow and restart the blood pump.
6. Check the arterial and venous pressures and press the
flashing pressure control to re-centralise the alarm
limits.
When the venous pressure is within the set alarm limits
again, the blood pump starts automatically.
