Traveling By Air

The FAA allows the Inogen One® G2 onboard all U.S. aircraft, here are a few points to make air

travel easy.

Planning Your Flight

When ﬂying with the Inogen One® G2, you must inform the airline that you will be using your

Inogen One® G2 onboard the aircraft. You must also keep a signed statement from

your physician with you that includes:

• Your ability to see/hear alarms and appropriately respond.

• When oxygen use is necessary (all or a portion of the trip).

• Maximum ow rate corresponding to the pressure in the cabin under normal operating

conditions.

16

• A new statement will not be necessary each time you y, 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.

• Because aircraft use different power port congurations, your Universal Power Supply is

equipped for use with two separate DC power adapters – a commonly used cigarette lighter

adapter, and a less common four-pin adapter (sold separately). Since it is difﬁcult to determine

which type of power supply your aircraft will have, it’s a good idea to keep both adapters

available when ﬂying.

Before Your Flight

Here are some things to keep in mind the day your ﬂight departs:

• 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 ight, 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.

• You should inform the airline you will be using your Inogen One® G2. Have your physician

letter with you and ready for inspection if requested.

English

During Your Flight

1. If using airline power port, remove the Battery from the Inogen One® G2 Oxygen

Concentrator. Due to aircraft power limitations, the Universal Power Supply cannot

be used to charge the Inogen One® G2 Battery when onboard aircraft.

2. Connect the appropriate DC Power Plug for the type of available airline power

(see photos on page 7 and 9). Check with airline personnel to ensure compatibility.

• During taxi, takeoff and landing, stow your InogenOne® G2 under the seat in front of you.

Your Inogen One® G2 will ﬁt upright under most airline seats. However, if it doesn’t ﬁt you

may turn it on its side.

• It is not necessary to turn off your Inogen One® G2 during taxi, takeoff and landing if your

physician’s written statement requires you receive oxygen during these periods.

CAUTION A change in altitude (for example, from sea level to mountains) may affect

total oxygen available to the patient. The Inogen One® G2 has been veriﬁed

to provide oxygen to speciﬁcation up to 10,000 ft (3048 m). Consult your

physician before traveling to higher or lower altitudes to determine if your

ﬂow settings should be changed.

After Your Flight

• Remember to recharge additional batteries you may have used prior to your next ight.

Traveling By Bus, Train or Boat

Contact your carrier to ﬁnd out about available power port availability.

Cannula Replacement

Your nasal cannula should be cleaned or replaced on a regular basis. Consult with

your physician and/or equipment provider and/or cannula manufacturer’s instructions

for cleaning and replacement information. A single lumen cannula up to 25 feet in

length to ensure proper breath detection and oxygen delivery is recommended.

CAUTION Use of a cannula other than a high ﬂow cannula (e.g. Salter 1600Q)

may restrict oxygen delivery and/or attachment to nozzle ﬁttings.
