Features

ImPulse™Elite Patient Manual
ImPulse™Elite is an electronic oxygen conserving device (OCD) that provides
convenience and mobility to patients with therapeutic oxygen needs. Designed
and manufactured by AirSep Corporation, ImPulse Elite uses portable cylinders
to provide patients with oxygen delivery at their prescribed dosages.
With this device, actual oxygen delivery to the patient occurs at or near the
beginning of the breathing cycle when the patient starts to inhale.
Because ImPulse Elite does not deliver oxygen during exhalation, which
accounts for approximately two-thirds of the breathing cycle, it wastes little or
no oxygen. This differs greatly from conventional oxygen systems that deliver
oxygen continuously. In addition, many patients are more comfortable with
oxygen conserving devices than continuous flow systems because they have
fewer problems with nasal dehydration that can result from constant flow into
the nostrils.
Maximizing Delivery with ImPulse Elite
ImPulse Elite’s advanced electronics enable it to respond effectively to a
patient’s respiratory cycle. ImPulse Elite senses the start of inhalation. Because
only a small amount of oxygen is actually required to oxygenate the blood
effectively, ImPulse Elite delivers the precise amount when it is most beneficial —
at the beginning of inhalation.
ImPulse Elite quickly delivers a pulse of oxygen compatible with your breathing
rate and automatically adjusts with any change in your breathing cycle —
depending on your prescribed oxygen requirement.
This method of oxygen delivery has been clinically tested and determined to
meet oxygen needs satisfied by comparable flow settings on continuous flow
units up to 6 lpm.
Initial Setup
As part of your initial set up with ImPulse Elite, your clinician may choose to
assess your saturation level through pulse oximetry. This helps to ensure
proper titration while using the oxygen conserving device.
Introduction

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 predeter-
mined unit settings, your breathing rate, and the length of daily ambulation time.
Most patients experience 10–18 months of battery life. AirSep strongly recom-
mends 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).
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.)
The green PULSE FLOW indicator
illuminates to indicate a good battery. If the battery requires
replacement, the green PULSE FLOW and yellow LOW BATTERY
indicators illuminate.
Turning On the Unit for Proper Oxygen Usage
Note
Do not use a mask with the ImPulse Elite unit.A mask may not conform to the face
properly enough for the unit to fully sense inhalation.
Do not use pediatric or low flow cannulas with the ImPulse Elite unit as their
smaller tubing diameters negatively affect delivery volumes.
Use ImPulse Elite during sleep only under the recommendation of a qualified
clinician.

1. Check the energy level of the battery each time you use the unit.
Refer to “Testing and Replacing Battery” for step-by-step instructions.
2. Check the oxygen cylinder setup and the cylinder contents gauge.
If you need to change cylinders, which includes removal and
reconnection of the ImPulse Elite unit, refer to Oxygen Cylinder
Connection for step-by-step instructions.
3. Make sure the PULSE FLOW / CONTINUOUS FLOW switch is moved
completely right (for pulse flow setting).
4. Set the ON/OFF switch to the ON position.
All three lights illuminate for less than 1 second. The
ImPulse Elite unit automatically calibrates and reaches
sensitivity within approximately 15 seconds. Then the
green light shuts off, and the unit emits a short burst of
oxygen. This indicates ImPulse Elite is ready for use.
5. Connect your cannula to the oxygen outlet. (You may
use up to a 25 ft [7.5 m] cannula, if desired.) (Figure 11.)
6. Turn the cylinder valve slowly one full turn counter-
clockwise to begin oxygen flow.
7. Make sure the cylinder contents gauge on the ImPulse Elite unit registers
within the green shaded/green zoned areas.
This indicates an adequate oxygen supply in the cylinder. (If the cylinder
contents gauge indicates the red REFILL zone, the
cylinder needs to be replaced.)
8. Position the nasal cannula with the prongs inserted
into your nostrils.
9. Set the flow selector between 1 and 6 depending on
your prescribed dosage (Figure 12).

Switching to Continuous Flow
If your unit is equipped with a continuous flow switch:
For very short time periods, this PULSE FLOW/
CONTINUOUS FLOW switch at the base of the unit can
be moved completely left for CONTINUOUS FLOW to
force the oxygen conserving unit to perform as a
continuous flow unit (Figure 13).
A typical use for the CONTINUOUS FLOW setting occurs
when the battery can no longer provide power. This setting
provides 2 lpm of continuous flow oxygen.
Before setting ImPulse Elite to CONTINUOUS FLOW,
make sure you set the ON/OFF power switch to the OFF position to preserve
battery life as this is a manual override and no audible or visual alarm
indicators are available in this “temporary” setting.
Caution
The continuous flow setting uses substantially more oxygen than the normally used pulse
flow setting. Make sure the cylinder contents gauge is observed often when operating the
unit as a continuous flow device.

Removing/Replacing the Cylinder
To easily remove the ImPulse Elite unit from a cylinder:
1. Close the oxygen cylinder valve by rotating the valve completely clockwise.
2. Press the BAT. TEST button OR temporarily set the PULSE FLOW/ CON-
TINUOUS FLOW switch to the CONTINUOUS FLOW setting until no
oxygen can be heard venting from the unit.
3. Turn the unit’s securing knob counterclockwise to lift the unit off the cylinder.

ImPulse™Elite Patient Manual
The ImPulse Elite unit and its accessories are light weight and portable. This
means that ImPulse Elite can go virtually anywhere you go.
Cautions
Do not expose the device to, or submerge it in, water.
Do not expose the device to extreme temperatures.
The universal-style carrying case, as shown in Figure 14, can be used with the
unit. During use, ImPulse Elite should remain in your carrying case. This
ensures added protection for the unit and
allows discreet use. Simply check periodi-
cally to ensure that your cannula connec-
tion is secure and that the cylinder shutoff
valve remains in the open position (one full
turn counterclockwise) to enable oxygen
flow.

ImPulse™Elite Patient Manual
Keep the ImPulse Elite clean and free from moisture, dust, and extreme
temperatures. To help prevent possible damage to the unit, keep ImPulse Elite
in its carrying case.
Clean the unit periodically by wiping with a lint-free cloth. Pay special attention
to the oxygen outlet for the cannula connection to make sure it remains free of
dust, water, etc. Do not expose or submerge the ImPulse Elite device in water.
We recommend using a one-part bleach to 99 parts water solution or using
Fantastik®spray cleaner as a safe cleaner for the ImPulse Elite’s outer
housing.
A list of undesirable chemical cleaning agents includes, but is not limited to
the following, according to the plastic manufacturer: alcohol and alcohol-
based products (isopropyl alcohol), concentrated chlorine-based products
(Ethylene Chloride), and oil-based products (Pine-Sol, Lestoil). These are
NOT to be used to clean the plastic housing on the ImPulse Elite OCD. These
chemicals and the cleaners that contain them will crystallize the plastic and
break down the plastic’s molecular properties.
Replace the disposable cannula periodically following normal usage.
Additional supplies are available from your Equipment Provider or AirSep.
Return empty oxygen cylinders to your supplier for replacement. Remove the
unit from the empty cylinder before returning the cylinder to your supplier.
Note
Do not open the electronic compartment to service the device. Open only the battery
compartment when necessary. To prevent a voided AirSep warranty, follow all
manufacturer’s instructions.
