Contraindications
Under certain circumstances, the use of non-prescribed oxygen therapy
can be hazardous. This device should only be used when prescribed by
a clinician.
Not for use in the presence of aerosol sprays orflammable anesthetics.
Additional monitoring may be required, as appropriate, for use by geriatric,
pediatric, or any other patient unable to hear, see or interpret alarms or
communicate discomfort.
The Oxlife Liberty®isnot appropriate for anypatient who would experience
adverse health consequences as a result of a temporary interruption in
oxygen therapy.
The availability of an alternate source of supplemental oxygen is
recommended in the case of power interruption or a mechanical failure of
the device. Consult your healthcare provider for a recommendation of an
alternate source of oxygen.
It is the patient’s responsibility to arrange for an alternate oxygen supply
when traveling. O2Concepts®assumes no liability forpersons choosing not
to adhere to manufacture recommendations.
Use of the device by patients with tracheotomy, under the recommendation of a

Section 2: Safety Guidelines
Device Safety Guidelines
AVOID EXPOSURE TO OPEN FLAMES OR CREATION OF ANY SPARK
NEAR YOUR OXLIFE LIBERTY. THIS INCLUDES SPARKS FROM
STATIC ELECTRICITY CREATED BY ANY TYPE OF FRICTION.
PROTECT ELECTRICAL POWER CORDS FROM SHARP EDGES TO
AVOID ELECTRICAL SHOCK AND SERIOUS PHYSICAL INJURY.
Locate the Oxlife Liberty® in a well-ventilated area to allow foradequate air
intake. Avoid the intake of airborne pollutants, smoke, or fumes. Wind or
strong drafts can adversely affect accurate delivery of oxygen therapy.
Use only approved accessories as specified in this User Manual. Use of
non-approved accessories may cause serious damage to the device and will
void the warranty.
Use only parts recommended by the manufacturer to ensure proper function
and to avoid the risk of fire and burns.
Incompatibleparts oraccessories can result in degraded performance.
Locate oxygen tubing and power cords away from hot surfaces and in a
manner to prevent tripping hazards.
DO NOT modify the device. Any modifications made to the device may
impair performance or damage equipment and will void the warranty.
DO NOT operate the device inan enclosed space, such as acloset, as it will
impair device function.
DO NOT cover the device orblock the sidevents or the exhaustports
located on the bottom of the device as it may impair device function.
DO NOT drop or insert any objects orliquid into any opening.
DO NOT leaveyour Oxlife Liberty®or batteries inyourvehicle or trunk.
Extreme heat or cold may damage your device and/or batteries.
DO NOT ship the Oxlife Liberty® with the battery installed. Batteries must be
shipped separately and packaged appropriately to avoid damage.
Keep the device away from potential household pests to avoid infestation
that will impair device performance and will void the warranty.

14
This device complies with Part15 of the FCCRules.
Operation is subject to the following twoconditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received,
includinginterference thatmay cause undesired operation.
Portable RF communications equipment (including peripherals such as
antenna cables and external antennas) should be used no closer than 12
inches (30cm) to any part oftheOxlife Liberty®including cables specified by
the manufacturer. Otherwise, degradation of the performance of this
equipment could result.
Use ofaccessories, transducers, orcables other than those specified by
O2 Concepts®could result in increased electromagnetic emissions or
decreased electromagnetic immunity of thedevice and result in improper
operation.
Use of the deviceadjacent toorstacked with other equipment should be
avoided because it could result in improper operation. If such use is
necessary, the device as well as other stacked equipment should be
observed to verify that they are operating normally.
Thedevice is suitable touseina CISPR 11 Group1Class B environment
for radiated emissions.

15
Patient Safety Guidelines
DO NOT SMOKE WHILE USING THIS DEVICE. KEEP ALL MATCHES,
LIT CIGARETTES, CANDLES, OR OTHER SOURCES OF IGNITION AT
LEAST 10 FEET FROM THE DEVICE. THIS DEVICE PRODUCES
ENRICHED OXYGEN GAS WHICH ACCELERATES COMBUSTION.
PRESCRIBEDMODE AND FLOW SETTINGS SHOULD ONLY BE
ADJUSTED UNDER THE ADVICE OF A PHYSICIAN.
Outdoor use must be conducted using battery power.
Monitor children andpets when inproximity tothe device.
Keep cannula tubingaway from children andpets to avoid danger
of choking or strangulation.
If you feel discomfort or are experiencing a medical emergency while
undergoing oxygen therapy, seek medical assistance immediately to
avoid harm.
DO NOT use the device with adamaged power cord or plug to avoid injury.
DO NOT operate thedevice onwet surfaces orinstanding water, and do not
submerge or expose to water or precipitation to avoid serious injury or
damage to the device. If the Oxlife Liberty® has been dropped, damaged,
or exposed to water please contact your authorized dealer or healthcare
provider for inspection and possible service of the device.
DO NOT come in contact with the device when wet to avoid serious injury
or the chance of shock.
Use only water-based lotions or salves that are oxygen compatible before
and during oxygen therapy. DO NOT use oil, grease, or petroleum-based
products on or near the device to prevent accidental ignition.
DO NOT lubricate fittings, connections, tubing or other accessories to avoid
the risk of fire and burns.
DO NOT use the device with an extension cord.
Open flames during oxygen therapy are dangerous and are likely to result in
fire or death. DO NOT allow open flames within ten (10) feet (3m) of the
oxygen concentrator or any oxygen carrying accessories.
Oxygen makes it easier for a fire tostart and spread.

16
DO NOT leave the nasal cannula or mask on bed coverings or chair cushions. If
the oxygen concentrator is turned on, but not in use, the oxygen will make the
materials flammable. Turn the oxygen concentrator off when not in use to
prevent oxygen enrichment.
SMOKING DURING OXYGEN THERAPY IS DANGEROUS and is likely to
resultinfacial burns ordeath.DO NOT allow smoking within the same room
where the oxygen concentrator or any oxygen carrying accessories are
located. If you intend to smoke, you must always turn the oxygen
concentrator off, remove the cannula and leave the room where the oxygen
concentrator is located. If you are unable to leave the room, you must turn
the oxygen concentrator off and remove the cannula before smoking.
To ensure youare receiving the therapeutic amount ofoxygen according to
your medical condition, the Oxlife Liberty® must be used only after one or
more settings have been individually determined or prescribed by a
physicianforyouat your specific activity levels.The OxlifeLiberty®mustbe
used with thespecific combination of parts andaccessories that were used
while your settings were determined.
Replace cannula as recommended by thecannulamanufacturer. Cannulas
may become contaminated with body fluids or expired gases during use.
Use of this device outside of the stated altitude, temperature or humidity
ranges is expected to adversely affect the flowrate and the percentage of
oxygen and, consequently, the quality of oxygen therapy.

17
Battery and Power Supply Safety Guidelines
Use ofnon-approved battery or power supplymay cause serious damage to
the device and will void the warranty.
Store the battery in a cool dry place when not in use to enhance battery life.
Remove the battery from the device ifitwillnotbeused for anextended
period of time to enhance battery life.

regulations require that the battery be removed from the device when
checked as luggage on international flights.
The battery may explode ifexposed to ordisposed of inafire.
Keep the battery away from children to prevent injury.
DO NOT drive over, drag or place objects on the power cords
to avoid damage.
Use of a frayed ordamagedACor DC powersupplycable maycompromise
basic safety with regard to the electromagnetic disturbances over the
expected service life.
DONOT attemptto disassemble the batteryor powersupply. Doing so will
void the warranty and may cause personal injury.
DO NOT usethebattery orpower supply for anything other than its intended
purpose. Doing so may damage the device or cause personal injury.
DO NOT drop the battery or expose it to mechanical shock. If the battery is
damaged, discontinue use and dispose of it properly to avoid personal injury.
DO NOT exposethebattery towater orother liquids. Ifthe battery gets wet,
discontinue use and dispose of it properly to avoid personal injury.
DO NOT exposethebattery toexcessiveheatorcoldoutsideof
specifications as it may affect performance.
Use caution when handling the DC plug adapter. This plug may get hot with
use. Ensure DC plugsocket isclean of debris which may cause overheating.
