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

• Maximum flow rate corresponding to the pressure in the cabin under normal operating
conditions.
16
!
C
!
C
Page 21
• A new statement will not be necessary each time you fly, but the statement should be
available during every flight.
• Some airlines may equip their aircraft with onboard electrical power. You may have an
opportunity to request a seat with a power port which can be used to power your Inogen One®
G2. However, availability varies by airline, type of aircraft and class of service. You should check
with your airlines for availability and always plan on having sufficient battery power for the
duration of your flight, plus a conservative estimate of unanticipated delays.
• Your universal power supply is equipped with a commonly used cigarette lighter adapter.
However, aircrafts use different power port configurations and it is difficult to determine
which type of power port compatibility your aircraft may supply; it’s a good idea to purchase
an adapter such as Magellan’s Em Power Socket Connector Item #EA270. Contact Magellan’s
at 800-962-4943 or visit www.magellans.com for a store location near you or purchase options online.

• Ensure your Inogen One® G2 is clean, in good condition and free from damage or other signs
of excessive wear or abuse.
• Bring enough charged batteries with you to power your Inogen One® G2 for the duration of
the flight plus a conservative estimate of unanticipated delays.
• Regional/Commuter airlines do not offer onboard electrical power. If your travel plans call for
flights on regional airlines, you will need sufficient battery power for the duration of the flight,
plus a conservative estimate of unanticipated delays.
CAUTION Airlines may not be equipped to provide backup oxygen.
• Arrive at the airport early. Airport security screening personnel may require extra time to
inspect your Inogen One® G2.
• While waiting to board your flight, you may be able to conserve battery power by using the
Universal Power Supply to power your Inogen One® G2 from an electrical outlet in the airport
terminal if available.
