Intended Use
The Oxlife Liberty®is a portable oxygen concentrator used on a prescriptive
basis that enables patients requiring supplemental oxygen to be treated in a
home, institutional, or vehicle/mobile environment.
The Oxlife Liberty®delivers 87%-95% pure oxygen toa patient through a
standard single lumen nasal cannula.
The Oxlife Liberty® is capable of delivering oxygen in both continuous flow and
pulse mode. In Pulse Mode the Oxlife Liberty® detects a patient breath and
delivers abolus ofoxygen during theinhalation period. In Continuous Mode the
device delivers a continuous flow of oxygen.
The Oxlife Liberty® can beset to deliver pulse flow rates in Settings 1 to 9 of
160 –1500mL/minute of oxygen (at 20 BPM) and can be set to deliver
continuous flow rates in Settings 0.5 to 1.5 LPM in .25 LPM increments.
The Oxlife Liberty2® can be setto deliver pulse flow rates in Settings 1 to10 of
160 –1600mL/minute of oxygen (at 20 BPM) and can be set to deliver
continuous flow rates in Settings 0.5 to 2.0 LPM in .25 LPM increments.
The Oxlife Liberty® has standard power options which include a 100-240VAC
power supply, a 10-15V DC power cord and a rechargeable lithium-ion battery.
Certain Oxlife Liberty®models may come equipped with O2 Concepts®Dynamic
Network Analysis® (DNA) Technology to provide equipment performance, usage
data and GPS location to O2 Concepts® via cellular connectivity.
User Profile
The Oxlife Liberty®issuitable for patients requiringsupplemental oxygen as
prescribed by a physician for the treatment of chronic pulmonary and
cardiovascular disease.

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 awell-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.

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 thanthose 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 to orstacked with other equipmentshould 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.

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. TheOxlife Liberty®must be
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.

Battery and Power Supply Safety Guidelines
Use ofnon-approved battery or power supplymaycause 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.
