7. Set the Inogen One® G2 Concentrator to the flow rate prescribed by your
physician or clinician.
Use the + or – setting buttons to adjust the Inogen One® G2 to the desired setting.
The current setting can be viewed on the display.
8. Position the nasal cannula on your face and breathe through your nose.
The Inogen One® G2 will sense the onset of inhalation and deliver
a burst of oxygen at a precise time when you inhale. The Inogen
One® G2 will sense each breath and continue to deliver oxygen
in this manner. As your breathing rate changes, the Inogen One®
G2 will sense these changes and deliver oxygen only as you need
it. At times, if you inhale very quickly between breaths the Inogen
One® G2 may ignore one of the breaths, giving the appearance of a
missed breath. This may be normal as the Inogen One® G2 senses
and monitors the changes in your breathing pattern. The Inogen
One® G2 will normally sense the next breath and deliver oxygen
accordingly.
A green light will flash each time a breath is detected. Make certain that the nasal cannula
is properly aligned on your face and you are breathing through your nose.
WARNING If you begin to feel ill or are experiencing discomfort while using this
device, consult your physician immediately.
CAUTION The Inogen One® G2 is designed to provide a flow of high purity oxygen.
An advisory alarm,“Oxygen Low”, will inform you if oxygen concentration
drops. If alarm persists, contact your equipment provider.
General
To remove power, unplug the input cord from its source (i.e., AC wall outlet, DC car
cigarette lighter adapter).
CAUTION Ensure the Universal Power Supply is powered from only one power source
(AC or DC) at any given time.The Universal Power Supply may not operate
properly if simultaneously powered using both AC and DC sources.
