TROUBLESHOOTING
Changing a Wet Transducer
1. Don appropriate PPE as per facility policy.
2. Stop the blood pump.
3. Clamp transducer line.
4. Remove wet transducer protector from connector on machine and
inspect the side connected to the machine for blood or priming solution
strike-through.
5. Carefully inspect transducer connector on AK 98 for fluid. If signs of
fluid strike-through, machine should be pulled as per facility policy
and an authorized service technician must replace the appropriate
components in the machine.
6. Remove wet transducer protector from line and discard per facility policy.
7. Attach a 10 mL syringe to the transducer line and unclamp the line.
To purge the transducer line of fluid, slowly inject 2-3 mL of air into the
transducer line until the fluid is removed from 1/2 to 2/3 of the line and
re-clamp the transducer line.
Note: Do NOT inject air too close, within approximately 4 inches, of
the T junction on the transducer line.
Note: If changing the venous transducer protector, slowly inject
2 mL of air into the line to the venous chamber.
8. Attach new transducer protector to pressure transducer line. Ensure
secure connection between transducer protector and line.
9. Attach transducer protector to AK 98, ensuring a secure connection
between transducer protector and machine.
10. Unclamp the transducer line and resume previous blood flow setting.
11. Verify arterial / venous pressure monitoring.

Note:
The time the blood pump is stopped may contribute to additional clotting. It is important to check the bloodlines
and dialyzer for clotting after the blood pump stops and therapy is restarted.

Air in Venous Drip
Chamber
Press Timer button,
then turn the knob to
increase drip chamber
level.
If level has dropped or foam is present in the chamber, touch the
clock symbol on the screen.
Attempt to resolve by SLOWLY increasing the level in the venous
chamber using the level adjustment knob, ensure that the blood
pump is moving.
1. Press the timer button that appears on the alert tab to turn on
the blood pump. At this point, the blood pump will rotate slowly at
50 mL/min and the speed cannot be changed.
2. Simultaneously rotate the chamber level adjustment knob counter-
clockwise to raise the blood level.
Be sure to watch for the message “Air no longer detected” and confirm
on the screen if appropriate.
May also require multiple attempts depending on the amount of air
present.
Note:
May also indicate clotting in the venous chamber. Be sure to
visually inspect the chamber for signs of clotting.

Blood Detected in
Dialysate Path
To start blood pump for
15 sec to rinse detector,
press Timer button.
Indicates that a blood leak may have occurred during treatment.
May occur immediately following priming of a new BiCart cartridge.
Follow your facility’s specific policy when a blood leak alarm occurs during patient
treatment.
