4-14 Respironics V200 Ventilator Operator’s Manual REF 1057983 A
Getting Started
Backup Battery Operation
When the backup battery is attached and the Respironics V200 Ventilator is op-
erating in normal ventilation mode anytime there is a loss of AC power, the ven-
tilator will automatically switch to battery power and continue ventilation
without interruption. Whenever the ventilator is powered by the backup battery,
it will generate a non-silenceable, non-resettable alarm that creates an alarm
sound every 60 seconds. During this state, the front panel indicator labeled “In
Use” (text version of the front panel as shown in Figure 4-17), or the battery
symbol (symbol version of the front panel as shown in Figure 4-18) will
illuminate yellow continuously. In addition, "Backup Battery On" is displayed.

Operation will continue in this state until the battery capacity is nearly expend-
ed. When the battery has only about 5 minutes of operation left, an audible,
nonresetable, HIGH priority alarm will sound. When this happens, the red,
front panel indicator labeled “Low” (text version of the front panel as shown in
Figure 4-17), or the low battery symbol (symbol version of the front pan-
el as shown in Figure 4-18) and the high priority alarm LED will flash continu-
ously. In addition, "Low Backup Battery" is displayed.
When power is finally depleted, the ventilator will open the Safety Valve and
terminate ventilation in an orderly fashion. In this state, the front panel dis-
plays "Backup Battery Depleted-Connect AC & Cycle Power." The backup alarm
emits a continuous tone, the high priority alarm LED flashes, and the Safety
Valve, Vent Inop, and Battery Low front panel indicators remain lit until power
from the Backup Battery is completely gone.
Battery Capacity
There is a great deal of variability in the power consumption of the ventilator
depending on altitude, ventilator settings, and the age and amount of charge
on the backup battery. These parameters will determine the exact amount of
time the ventilator can operate from the backup battery.
WARNING: When the battery low indicator is flashing red, operation of the ventilator
from the battery power should be discontinued.
