2. SETTING UP A PATIENT ON INOGEN ONE G3
2.1. Indications for Use
TheInogenOneG3OxygenConcentratorisusedonaprescriptivebasisbypatientsrequiring
supplemental oxygen. It supplies a high concentration of oxygen and is used with a nasal
cannula to channel oxygen from the concentrator to the patient. The Inogen One Oxygen
Concentrator may be used in ahome, institution,vehicle and variousmobile environments.
NOTE
Availability of an alternate source of oxygen is recommended in case of power
outage. Several certifying bodies for HomeHealth Care Providers require that
back-up oxygen be available to the patient. Supplemental oxygen cylindersor
extra Inogen One G3 Batteries may satisfy these requirements.
CAUTION
Oxygen demand of some patients, particularly those with high breathing rates
and high flow settings, may exceed the capabilities of the Inogen One G3. Inogen
suggests that each patient be titrated to assure that theInogen One G3 is an
appropriate solution for their needs.
2.2. System Components
The following are standard components of the Inogen One system:
oInogen One G3 Oxygen Concentrator
o8 Single Battery, BA-300
oAC to DC Power Supply, BA-301
oDC Power Cord

2.3. Using the Inogen One G3
To quickly configure the InogenOne G3 for patient use:
1. Slide the battery onto the bottom of the system until the latch clicks into place.
2. Connect AC power cord to the power supply.
3. Connect the power supply to the Inogen One G3.
4. Plug into closest AC outlet
5. Turn on the Inogen One G3 by pressing the on/off button.
6. Set the Inogen One G3 to correct flow setting prescribed by the physician or clinician
by pressing the + (increase flow) or (decrease flow) button.
7. Attach cannula to the metal hose barb located next to the handle of the Inogen One
G3.
For further information regarding the use of the Inogen One G3, please consult the User
Manual.
2.4. Selecting the Proper Flow Setting
2.4.1. Bolus Volumes Specification
All oxygen conserving devices function differently, and therefore it is prudent
to titrate patients for any new conserving device. Delivery timing, bolus volume, and
FiO2),
saturation.
As an oxygen concentrator, the Inogen One G3 does not contain a finite storedvolume
of oxygen, such as withcompressed gas or liquid cryogenic systems. The Inogen One
G3 can provide oxygen to the patient as long as a source of electricityis available.
However, because the oxygen is being produced as it is used, supply of oxygen is rate-
limited . The Inogen One G3 delivers up to 1050ml/min of 90% oxygen (earlier models
deliver up to 840 ml/min of 90% oxygen).
At each flow setting, the Inogen One generates a specific amount ofoxygen (210ml per
setting), and the on-board OCD attempts to deliver all of this product to the patient.
This is equivalent to a conserving ratio of 4.76 at all flow settings and breathing rates.

Slower breathing patients will receive larger boluses, and faster breathing patients will
receive smaller boluses.
DESIGN
NOTE
This method of bolus volume determination is similar to what is experienced by a
patient using a continuous flow concentrator actual alveolar oxygen inspiration
is more closely linked to flow setting than to breathing rate.
In general, the Inogen One G3 delivers 14ml per bolus per flow setting at 15 breaths per
minute (210ml/min per flow setting). The following table summarizes the bolus
volumes delivered by the Inogen One OCD at 20Cand Sea Level:

DESIGN
NOTE
Bolus Volume is tunedto provide the correct bolus volume when delivered
through a nasal cannula such as the Salter Labs 1600Q. If bolus volumes are
measured without a cannula or with a different type of nasal cannula, bolus
volumes will vary fromvalues stated in the table above.
2.4.2. Trigger sensitivity
The conserver will trigger when the negative pressure at the internalsensor reaches -
0.12 cm H20 (+/- 20%). This low trigger sensitivity allows for breath detection ofvery
shallow breathing, but may also result in the occasional trigger due to motion of the
cannula or motion of the concentrator. The trigger sensitivity may vary
2.4.3. Flow Setting Selection Relative to Physician Prescription
Inogen has labeled each of the four settings to provide a guideline for matching the
setting of the device to the continuous flow prescription issued by thephysician.

3.2. Maintenance by the Patient
3.2.1. Cannula Replacement
The nasal cannula should be replaced on a regular basis. A single lumen cannula of four
to 25 feet in length must be used. Inogen has certified its performance data with the
Salter Laboratories 1600Q cannula.
CAUTION
Do not use total cannula tubing length exceeding 25 feet with the Inogen One G3
unless proper saturation has been verified by a clinician.
3.2.2. Intake Filter Cleaning
At thefrontofthe InogenOne G3, ambientairpasses through twogross particlescreens
that removes dust fragments. This particle screen must be cleaned on a weekly basis to
ensure adequate air flow through the device. If the particle screen is not cleaned
frequently, the life expectancy of the concentrator will be shortened due to higher
internal operating temperatures.
Particle screens should be cleaned using a mild detergent (e.g., dishwashing solution,
such as DawnTM) and water solution; be sure the filter is rinsed in water and allowed to
air dry before reuse. Additional replacement filters may be obtained from Inogen (RP-
300 or RP-301). There are other types of filters inside the Inogen One G3 that provide

3.2.4. Battery Care and Maintenance
The Inogen One G3 Lithium Ion Battery requires special care to ensure proper
performance and long life. Use only Inogen One G3 Batteries with the Inogen One G3
Oxygen Concentrator.
DESIGN
NOTE
The Inogen One G3 Oxygen Concentrator adjusts its oxygen production rate to
match the oxygen demand specified by the user flow setting. When the device
is used at lower settings, its battery life is extended. Additionally, at lower
flow settings, the concentrator does not generate as much heat and noise,
draw as much electric current from external power supplies, and many system
components do not wear as quickly.
Initial Battery State
The Inogen One G3 batteries are shipped 40% to 100% charged.
The battery can be used immediately; however, we recommend the battery be
charged upon receipt to ensure adequate run time.

2 to 4.5 hours using the standard 8 cell pack (BA-300) under most environmental
conditions. To maintain maximum run-time of the battery, users should avoid
running in temperatures less than 40oF (4oC) or higher than 95oF (35oC) for
extended periods of time.
The number of cycles that the battery will last is highly dependent upon the
temperature at which the battery is charged. Inogen recommends that batteries
not be charged at roomtemperatures exceeding 75oF (24oC).
DESIGN
NOTE
The BA-300 and BA-316 will typically achieve 500 charge/discharge cycles while
retaining 80% of their original capacity if proper battery care is taken.
Battery Time Remaining Clock
The Inogen One G3 continuously displays battery time remaining. It may be
necessary to inform the user that this displayed time is onlyanestimate , and the
actual time remaining may vary from this value.
To avoid running out of battery power unexpectedly, users should regularly
monitor the displayed battery time remaining and/or carry a back-up power
supply (extra charged battery or AC Power Supply).
Storage
Instruct patients to remove the battery from the Inogen One G3 when it is not in
use to avoid inadvertent discharge. Leaving a battery attached to an idle Inogen
One G3 for prolonged periods will result in battery damage that will severely
shorten the expected life of the battery.
DESIGN
NOTE
When the concentrator is off but the battery installed, the battery will continue to
power draw will empty a full battery in approximately 2-3 weeks.
CAUTION
Leaving a Battery in theInogen One G3 while the device is unused will irreversibly
damage the battery. After such storage, the battery may not beable to recharge

or its life cycle and/or capacity will be greatly diminished. A full battery can be
damaged in as little as 20 days if left in the concentrator whilenot plugged in.
Instruct users to avoid storing the Inogen One G3 battery in extreme
temperatures, below -4oF (-20oC) or above 140oF (60oC), for any amount of time.
They should avoid leaving batteries in automobiles, where these temperatures
can be regularly exceeded. Storage of the Inogen One G3 battery in a cool, dry
location will help to maximize the longevity of the battery.
