Changing the Dialyzer and Blood Line During Treatment
Replacing the BiCart Cartridge During Treatment
If clotting occurs, you may have to change the blood line and dialyzer during treatment. If you must replace the dialyzer and blood
line during treatment, all values and settings will be saved in the machine, and treatment will resume from where it left off.
Note: It is not necessary to end the treatment and start again to replace the circuit. Once the procedure is complete, the
treatment will continue from when it was stopped.
Note: It is important to follow the instructions provided on the operator’s panel in the sequence listed. Steps performed out of
sequence may delay the option for priming and return to treatment mode. Once started, the new blood circuit procedure
must be completed.
1. Press Functions.
2. Select New Blood Circuit and Confirm. The blood pump stops automatically.
3. Confirm New Blood Circuit with blood return when the blood pump stops.
4. Prepare for rinse back using the rinse back line on the arterial infusion line.
5. Select Rinse Back and Confirm.

treatment:
