How to run the Access Flow test

Figure 51 – Starting an Access Flow Test
When the Access Flow button is turned ON, the machine will offer to do the Access Flow
test following the next OLC test. The Access Flow button may be left in the Off position and
turned On later. If desired, select the Manual OLC Test and press CONFIRM after turning
the Access Flow ON to begin the test right away. If you display the "Kt/V AF" screen while
doing the test, more detailed instructions are displayed.
Warning! The Access Flow procedure requires that the bloodline connections to the access
needles be reversed and later returned to their original position. To avoid the possibility of
significant blood loss, be sure that the connections are well secured after disconnecting and
reconnecting the bloodlines.
Warning! Use aseptic technique when doing this procedure.
Warning! Return the bloodlines to the original position (red to red and blue to blue) when
the test is completed. Failure to do so will result in lower delivered therapy.
Note: If the access flow rate is less than or equal to the blood pump rate, the access flow rate
will be calculated and reported as approximately the blood pump rate. In this case, the
access flow rate may be lower than indicated.
Note: During the second OLC measurement for the Access Flow test, the UF will change to
70 if running low flux or 300 if running high flux.
