2. SETTING UP A PATIENT ON INOGEN ONE G3
2.1.Indications for Use
The Inogen One G3 Oxygen Concentrator is used on a prescriptive basis by patients
requiring 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 a home, institution, vehicle and various mobile
environments.
NOTE
Availability of an alternate source of oxygen is recommended in case of
power outage. Several certifying bodies for Home Health Care Providers
require that back-up oxygen be available to the patient. Supplemental
oxygen cylinders or 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 the Inogen
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
oCarry Bag
oCannula
Patient Set-Up. To properly set up a patient on the Inogen One G3 System, you may
need to provide:
oPulse Oximeter (for titration, not included)
oExtra cannulas (not included)
2.3.Using the Inogen One G3
To quickly configure the Inogen One 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.

TECHNICAL MANUAL Page 5 of 16
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 (OCD’s) function differently, and therefore it is prudent
to titrate patients for any new conserving device. Delivery timing, bolus volume, and
oxygen concentration all contribute to a patient’s fraction of inspired oxygen (FiO2),
and therefore to the OCD’s efficacy at maintaining the patient’s blood oxygen
saturation.
As an oxygen concentrator, the Inogen One G3 does not contain a finite stored
volume of oxygen, such as with compressed gas or liquid cryogenic systems. The
Inogen One G3 can provide oxygen to the patient as long as a source of electricity is
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 1050 ml/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 of oxygen (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 20C and Sea Level:

DESIGN
NOTE
Bolus Volume is tuned to 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 from values stated in the table
above.
2.4.2. Trigger sensitivity
The conserver will trigger when the negative pressure at the internal sensor reaches -
0.12 cm H20 (+/- 20%). This low trigger sensitivity allows for breath detection of very
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 the physician.
Actual correlation is dependent upon the patient’s breathing rates, inspiratory tidal
volume, and other physiologic factors. Inogen suggests that each patient be titrated
(a) while sedentary, (b) while active or ambulatory.
2.4.4. Use with the Inogen Satellite Conserver
The Inogen One G3 is not compatible with the Inogen One Satellite Conserver

in characteristics of the equipment.
3. Visually inspect the device, batteries, and accessories for cracks or other
damage.
4. Feel the sides of the device for vibration and listen for unusual noises, rattles,
or other signs that the device requires service.
CAUTION
Discovery of cracks or other types of external damage may be
indicative of other internal damage that may not be visible. If such
external damage is discovered, be certain to inquire as to how it
occurred, and whether any changes in the device have been noticeable
since its occurrence. If you have any concern over the safety of the
device, arrange for equipment servicing.
3.1.6. Product Filter
This filter is intended to protect the user from small particles in the product gas flow.
The Inogen One G3 includes a product filter, conveniently located behind the
removable cannula nozzle fitting. Inogen suggests that this filter be replaced between
patients.
To replace the Product Filter:
1. Use the Cannula Barb Tool (available from Inogen as RP-102) to access the
product filter. The tool has two prongs which mate with two indentations
located on the surface of the metal cannula barb fitting on the Inogen One
G2.
2. Carefully remove the cannula fitting by unscrewing it in the counter-
clockwise direction.
3. The filter, a hard plastic disk with a silicone gasket on its outer edge, will be
visible in the recess once the hose barb is removed.
4. Remove the filter, and inspect the recess to make sure it is free of debris.
5. Install a new replacement filter.
6. Carefully screw the cannula barb fitting back into the recess (clockwise) until
it bottoms out on the filter gasket. Take care to squarely screw the nozzle
fitting into the threads, and not to over tighten.
WARNING
Failure to inspect and replace the product filter may result in the filter
becoming clogged or obstructed over time, and in reduced delivery of
oxygen to the patient.
3.1.7. Oxygen Purity Check
The oxygen concentration can be checked using the Salter Labs PrO2 Check
ultrasonic oxygen analyzer. The concentrator should be run for 10 minutes before
measuring the oxygen concentration. If the concentrator has not been used for more
than 2 weeks, the concentrator should be run for a minimum of 30 minutes to allow for
adjustments to the operating parameters prior to measuring the oxygen concentration.

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 the front of the Inogen One G3, ambient air passes through two gross particle
screens 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 additional filtration. Maintenance of these filters is not required under normal
operating conditions.
3.2.3. Surface Cleaning
The outside case should be cleaned using a cloth dampened with a solution of mild
detergent (e.g., dishwashing detergent, such as DawnTM) and water. Avoid getting
water in or around the battery connectors, power jack, or vents.
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.

INOGEN ONE G3 OXYGEN CONCENTRATOR
TECHNICAL MANUAL Page 12 of 16
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.
Normal Charging
The battery is operating properly when a battery icon is displayed on the LCD
screen.
The Inogen One G3 batteries do not have a “memory” like older NiCad battery
packs. The Inogen One G3 batteries can be partially charged and discharged
without damaging the battery packs.
Effect of Temperature on Battery Performance
The Inogen One G3 battery powers the Inogen One G3 Oxygen Concentrator
from 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 room temperatures 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 only an estimate, 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).

TECHNICAL MANUAL Page 13 of 16
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 provide a small amount of power to the
concentrator’s microprocessor. This power draw will empty a full
battery in approximately 2-3 weeks.
CAUTION
Leaving a Battery in the Inogen One G3 while the device is
unused will irreversibly damage the battery. After such storage,
the battery may not be able 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 while
not 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.
