AK 98 Dialysis Machine - Handling the dialysis machine A:71
3.5.4 To automatically enter concentrate standby mode
The following conditions can be preset (by an authorised service technician) to
pause dialysis fluid preparation:
ā When the green fluid path is achieved, or a preset time thereafter.
ā When the set priming volume is achieved.
The machine can be preset to activate concentrate stand-by mode, and at the same
time shut off the water intake. In this case, the consumption of both water and
concentrates are paused.
3.6 Operate the machine during power failure
3.6.1 Power failure with battery back-up
If the dialysis machine loses power, it has a back-up battery that temporarily provides
power to the blood unit. All settings and actual values are kept. The blood pump will
continue to operate on battery power. Heating of dialysis fluid is not provided.
The back-up battery will only last a limited time, 30 minutes can be expected from a
fully loaded battery in good condition.
NOTE!
Consider whether to discontinue treatment if the power failure is expected to last
more than a few minutes.
If the dialysis machine loses power and the back-up battery does not work, the dialysis
machine shuts down. All settings and actual values are kept, see Section 3.6.3 āReturn
the blood to the patient manuallyā on pageīA:71.
3.6.2 Power failure without battery back-up
If the dialysis machine loses power it shuts down. All settings and actual values are
kept.
Continue the treatment after power failure
Press the On/Off button to start the machine when the power returns. The machine
will recover and continue the treatment from where it was stopped. All settings and
actual values are kept. However, all treatment parameters need to be checked by the
operator after a recovery.
CAUTION!
After recovery, check treatment parameters to ensure that treatment is continued
according to prescription.
3.6.3 Return the blood to the patient manually
WARNING!
During manual procedure to return blood to patient during a power failure, the
operator shall take full responsibility for visually monitoring all safety parameters that
cannot be monitored by the machine during a power failure (for example air
detection).
WARNING!
Check that the arterial blood line is connected to the rinseback solution to prevent
patient blood loss.
If the dialysis machine is shut down, you can manually return the blood to the patient.
