19.13 Drain Logic Options
19.13.1 Standard Fill Mode Drain Logic
The HomeChoice/HomeChoice PRO APD System drains until the system encounters
Slow Flow from the patient line for a period of time, or a single pump stroke of
No Flow from the patient line.
If Slow Flow persists for a preset period of time, the system looks at the Minimum
Drain Volume to determine what to do next.
 If the Minimum Drain Volume has not been met, a 3-beep auto restart
LOW DRAIN VOLUME alarm is posted. If this alarm repeats, it is promoted
first to a 6-beep auto restart alarm, and then a continuous beep alarm that
requires operator intervention.
 If the Minimum Drain Volume has been met, the system will set the
patient volume to zero (0) and move on to the Fill phase.
If No Flow occurs, the system checks to see if the No Flow condition also applies to
flow to the patient.
 If the No Flow condition applies to both outflow and inflow, a CHECK
PATIENT LINE alarm occurs.
 If the “pushback” flows normally toward the patient, the system looks at
the Minimum Drain Volume to determine what to do next.
– If the Minimum Drain Volume has not been met, a 3-beep auto restart
LOW DRAIN VOLUME alarm occurs. If this alarm repeats, it is
promoted first to a 6-beep auto restart alarm, and then a continuous
beep alarm that requires operator intervention.
– If the Minimum Drain Volume has been met, the system will set the
patient volume to zero (0) and move on to the fill phase.
The Minimum Initial Drain Volume setting is made in the Make Adjustments menu.
The Minimum Drain Volume percent setting is made in the Nurse’s Menu. The
Drain Volume percent is multiplied by the Day Fill Volume for day drains and the
Night Fill Volume for night drains.
