Low Arterial Pressure

Stop the blood pump. The arterial and venous pressure alarm limits are automatically
widened.

Check that the patient´s blood flow rate is the same as the blood flow rate set in the
dialysis machine.

Check the patient´s blood pressure.

Check the position of the arterial needle.

Consider lowering the pump speed while the pump is stopped using the blood pump
down button (-) to the right of the screen.

Correct the cause of the alarm and restart the blood pump.

May indicate a mechanical obstruction - access patency issues, kinks, or poor flow
within vascular access related to the set pump speed.

Check the transducers for potential strikethrough.
120
Low Venous Pressure
Check the venous
needle position or
catheter lumen.

Stop the blood pump. The arterial and venous pressure alarm limits are automatically
widened.

Check that the venous blood line is properly attached to the dialyzer.

Check that the venous needle is in proper position.

If this alarm occurs during functional check, restart the machine using the On/Off
button and the machine will perform a new functional check.

Check that there are no clots before or in the dialyzer.

Adjust the blood flow rate and restart the blood pump.

Check the transducers for potential strikethrough.

Consider needle dislodgement, potential clotting before the dialyzer,
or a wet transducer protector.

Technical Error
The machine has
been automatically
restarted. To continue
press Confirm.

Press the Confirm key on the screen to continue treatment.

Proceed to the Functions key, Service, and then to the Error List
tab at the top of the screen. Note the error code on the Error List
(most recent at the top).

If this alarm occurs during functional check, restart the machine
using the On/Off button and the machine will perform a new
functional check.

If the alarm recurs, contact Technical Services and provide the
full error code. AK 98 is continuously supervising the computers
used to run treatment. If the system identifies a problem, it will
generate an automatic restart to restore a fully operational system.
124
Technical Error
Contact technical
service.

If this alarm occurs during functional check, restart the machine using the On/Off
button and the machine will perform a new functional check.

Ensure the dialysate line connector nuts are tight.

Ensure the dialysate connectors are properly seated on their dialysate ports.

Ensure there are no parts of the blood tubing strung on the machine before the blood
pump button is flashing.

Verify that the acid concentrate connector and BiCart arms are free of build-up.

Power the machine on. If the alarm recurs, consider contacting Technical Services.

Proceed to the Functions key, Service, and then to the Error List tab at the top of the
screen. Note the error code on the Error List (most recent at the top).
Note: This is not possible during treatment. If the alarm occurs during a treatment,
you may be able to complete a rinse back. Follow your procedures.

Heparin Pump is
Overloaded
Check heparin line for
obstruction.

May occur during machine start up if the heparin pump is too close to the housing; pull
piston out to the right.

May be triggered by a closed clamp on the heparin infusion line or the heparin syringe
is empty.

Consider setting the heparin flow rate to 0 mL if the syringe is empty.

If alarm recurs, consider removing the syringe from the pump and pulling the piston
out to the right.
