19.14.2 Unscheduled Replenish
If the heater bag empties before the end of the Fill phase, the system will usually,
but not always, transfer solution from the supply bags to the heater bag in order to
complete the Fill phase. This is an unscheduled replenish because the heater bag
ran dry unexpectedly during Fill.
An unscheduled replenish is performed if the Fill Volume delivered to the patient
when the heater bag empties is less than the volumes shown in the Table 19-6 on
page 19-14. If the delivered Fill Volume is greater than the amounts shown in the
table, the system considers the Fill complete and transitions from the Fill phase to
the Dwell phase.
19.15 Determining Maximum Fill Volume
Table 19-7 on page 19-15 allows you to determine the highest Fill Volume that
should be programmed for a given dry weight. This information allows you to
verify that the entered Fill Volume is not accidentally programmed too high for
you or a caregiver’s patient. In fact, most patients require a Fill Volume that is
much lower than the values listed in this table.
Table 19-6. Unscheduled Replenish Logic
Fill Descriptions Unscheduled Replenish
Day Fill 1 Volume Delivered < 90% of Fill Volume
Day Fill 2 and up Volume Delivered < 100% of Fill Volume
Fill 1 of n Volume Delivered < 90% of Fill Volume
Fill 2 thru n-1 Volume Delivered < 100% of Fill Volume
Fill n Volume Delivered < 75% of Fill Volume
Last Fill Volume Delivered < 75% of Fill Volume

NOTE:
An alarm is posted when there is insufficient fluid to complete an
unscheduled replenish. This alarm can not be bypassed. To return to
Fill, see 18.4.7, Check Supply Line Alarm During Replenish, on
page 18-52.
