General information
About the backup
battery
WARNING: To reduce the risk of power failure to the ventilator, pay close attention to
the battery’s charge level. The battery’s operation time is approximate and
is affected by ventilator settings, discharge and recharge cycles, battery
age, and ambient temperature.
NOTE: The backup batteries are intended for short-term use only. They are
not intended to be a primary power source.
NOTE: We recommend that the ventilator’s batteries be fully charged before
you ventilate a patient. If the batteries are not fully charged and AC
power fails, always pay close attention to the level of battery charge.
NOTE: A new backup battery should be installed and charged within one year
of the date of manufacture identified on the battery and on the
shipping box.
NOTE: Storing a battery for an extended period of time after its manufacture
date without being put into service, or at temperatures that exceed its
limits, increases the risk of discharge whereby the battery is unable to
be recharged by the ventilator.
NOTE: Batteries that are not installed in the ventilator should be stored
at -20 to 25
ºC
and charged at least once per year.
NOTE: Lithium Ion batteries are shipped with a charge level of under 30%,
which may further impact the time until the battery is charged and
discharged.
The internal backup battery protects the ventilator from low, or failure of, AC
(mains) power. If AC power fails, the ventilator automatically switches to
operation on backup battery with no interruption in ventilation. The battery
powers the ventilator until AC power is again adequate or until the battery is
depleted. For electrical specifications, see Table 11-10 on page 11-8.
As a safeguard, the ventilator provides a low battery alarm. It also has a
capacitor-driven backup alarm that sounds for at least 2 minutes when battery
power is completely lost.
The ventilator charges the battery whenever the ventilator is connected to AC,
with or without the ventilator switched on. The Battery (charged) LED flashes
to show that the battery is being charged.
Check the battery charge level before putting a patient on the ventilator and
before unplugging the ventilator for transport or other purposes. The power
source symbol at the bottom right-hand corner of the screen shows the power
source in use and, if the ventilator is running on battery, the level of battery
charge (Figure 3-6).
NOTE: The battery charge level displays within about a minute of power on.
If the battery is not fully charged, recharge it by connecting the ventilator to
AC power for a minimum of 5 hours. Pressing the Help button shows you the
approximate time remaining until the battery is fully charged. If the battery is
not fully charged within 16 hours, or the ventilator displays a Check Vent:
Battery Failed alarm, replace the battery.
