8. Position the nasal cannula on your face and breathe through your nose.
The Inogen One® G4 will sense the onset of inhalation and deliver
a burst of oxygen at a precise time when you inhale. The Inogen
One® G4 will sense each breath and continue to deliver oxygen in
this manner. As your breathing rate changes, the Inogen One® G4
will sense these changes and deliver oxygen only as you need it. At
times, if you inhale very quickly between breaths the Inogen One®
G4 may ignore one of the breaths, giving the appearance of a
missed breath. This may be normal as the Inogen One® G4 senses
and monitors the changes in your breathing pattern. The Inogen
One® G4 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® G4 is designed to provide a flow of high purity oxygen. An
advisory alert, “Oxygen Low”, will inform you if oxygen concentration drops.
If alert persists, contact your equipment provider.
