FAA safety rules. For example:
1. Some seats on an aircraft, such as bulkhead seats, may or may not have approved stow-
age space to accommodate a Zen-O lite™ POC during movement on the surface, take-off,
and landing. Therefore, the Zen-O lite™ POC may not be able to be stowed properly dur-
ing these phases of flight if the Zen-O lite™ user occupies those seats. In this case, a seat-
ing restriction may apply
2. During movement on the surface, take-off, and landing, the nasal cannula tubing that
is used to dispense oxygen from your properly stowed Zen-O lite™ POC may not stretch
EN
across the row in such a way as to restrict passenger access or become a tripping hazard
in an evacuation. You must not restrict another passenger's access during these phases of
flight. In this case, a seating restriction may be required to comply with an FAA safety rule.
For example, if all seats in the row are occupied, the appropriate seat for the Zen-O lite™
POC user would be a window seat.
3. An operator can only establish seating restrictions based on FAA safety rules. The exam-
ples above represent some, but not all, scenarios to consider.
IMPORTANT: A general airline policy that all passengers who board the aircraft with a Zen-O lite™
POC must occupy a window seat, without regard to the specifics of the individual situation, would
be inconsistent with FAA requirements.
8.2.5. Cabin Depressurisation
There is no danger posed by a Zen-O lite™ POC that is operating during a loss of cabin pres-
sure. However, in the case of loss of cabin pressure (rapid or slow), you should use the oxygen
masks that deploy until the aircraft stabilises.
8.2.6. Use of Aircraft Electrical Power
There is no requirement for operators to provide aircraft electrical power to a Zen-O lite™ POC
user. Electrical outlets on board aircraft are considered nonessential equipment and are not
required by the applicable certification or operational rules. In addition, electrical malfunc-
tions in aircraft systems may require the power source to these outlets to be deactivated on
the ground or in flight for the safety of the flight. Due to this statement, the Zen-O lite™ POC
should only be operated off battery power while on board aircraft. You should never rely
upon onboard aircraft electrical power being available during a flight
8.2.7. Smoking
Smoking (including e-cigarettes) during oxygen therapy is dangerous and is likely to result
in serious injury or death of the patient and others from fire. Do not allow smoking or open
flames within 10 feet of the portable oxygen concentrator or any oxygen carrying accessories.
8.3. Transportation Security Administration (TSA) Requirements
Detailed information that is pertinent to passengers using respiratory devices, including Zen-
O lite™ POCs, may be obtained from the TSA at https://www.tsa.gov/travel/special-procedures.
