Testing and Replacing Battery
ImPulse Elite requires just one 1.5 volt “D” size
alkaline battery (Energizer recommended) for
full operation. Battery life is dependent upon the
predetermined unit settings, your breathing rate, and
the length of daily ambulation time. Most patients
experience 10–18 months of battery life. AirSep
strongly recommends that you maintain a spare
battery in your carrying case for replacement in this
unit as necessary.
To install or replace the battery, follow the steps
below:
1. Make sure the ON/OFF power switch is set
to the OFF position. (It is not necessary to
disconnect the cannula or remove the ImPulse
Elite from the cylinder, although you may find
it easier to replace the battery within the battery
compartment door if the unit is first removed
from the cylinder.)
2. If the unit is not connected to the cylinder,
simply hold the unit with one hand while you
press in and lift up on the battery compartment
latch with your other hand. (Figure 7).
Figure 7
If the unit is connected to the cylinder, steady
the unit by grasping the neck of the cylinder
just below the unit with one hand while you
press in and lift up on the battery compartment
latch with your other hand (Figure 8).

3. Insert a fully charged battery into the inside
door of the battery compartment. Make sure
the battery is properly positioned to match the
correct positive and negative polarity markings
(Figure 9).

To test the battery to ensure that there is proper
power available to operate the unit:
1. Make sure there is a battery in the unit’s battery
compartment and it is properly positioned to
match the correct positive and negative polarity
markings.
2. Make sure the ON/OFF power switch is set to
the ON position.
3. Press and hold down firmly the center of the
BAT. TEST button with your finger. (Figure
10.) (You can test the battery regardless of
whether or not a cannula is connected to the
oxygen outlet.)
