TROUBLESHOOTING
What to Do During a Power Outage

If the machine loses power, a backup battery will temporarily power the
blood unit. All settings and actual values will be saved.

The blood pump and heparin pump will continue to operate using
battery power, but dialysate preparation will stop. The machine will
enter bypass mode and the dialysate line will appear gray.

The back-up battery will only last a limited time. 30 minutes can be
expected from a fully loaded battery in good condition.

If the power outage is expected to last for more than a few minutes,
consider discontinuing the treatment.
Using the Machine During a Power Outage

When power is restored, the machine automatically resumes the
treatment and asks the user to confirm the restart.

The treatment will resume from where it left off, and all settings and
actual values will be saved. However, the user must double check all
treatment settings.
Continuing Treatment After a Power Outage

If the blood pump cannot be started, the user may
manually rinseback blood to the patient.

Since the machine's safety features are inactive while
the machine is turned off, you must consider the risks
that may occur during manual rinseback.
1. Close the arterial blood line and patient arterial access clamps.
2. Disconnect the arterial blood line from the patient.
3. Connect the arterial blood line to the rinseback line, and open the
appropriate clamps on the arterial blood line, rinseback line, and
infusion line.
4. Remove venous line from venous line clamp.
5. Open the blood pump door.
6. Rotate the blood pump counter-clockwise to return the blood.
Ensure no air enters the patient.
7. Once rinseback is completed, clamp the venous blood line and
patient venous access clamps.
8. Disconnect the venous blood line from the patient.
