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.
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 (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:
