TECHNICAL MANUAL
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 function differently, and therefore it is prudent
to titrate patients for any new conserving device. Delivery timing, bolus volume, and

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.
