B:58 AK 98 Dialysis Machine - Alarms
HCEN12745 Revision 10.2016
Program version 2.xx
215 Single needle stroke volume is too low
215 Single needle stroke volume is too lowī¼
Appears:
When the measured stroke volume is lower than the set
stroke volume in single needle treatment.
The performance of the patient's blood access may be
decreased.
The single needle treatment may not be optimised.
Machine actions:
None.
Operator action:
1. Check the level in the expansion chamber. It should be
as low as possible but air should not pass into the blood
lines at the end of the venous phase.
2. If possible, adjust the venous pressure alarm window.
The wider the window, the greater the stroke volume.
The higher the position of the window (i.e. how high in
the mmHg scale the window is placed), the higher the
venous flow.
3. If previous steps do not help, adjust the stroke volume
in the dialysis machine:
- Press the Blood button.
- Select the Single needle tab.
- Press Minimum stroke volume limit.
- Adjust the limit value.
