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 to a 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 a bolus of oxygen during the inhalation period. Incontinuous mode the
device delivers a continuous flow of oxygen.
The Oxlife Liberty® can be set 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 Liberty® has standard power options which include a 100-240V AC
power supply, a 10-15V DC power cord and a rechargeable lithium-ionbattery.
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 adult patients requiring supplemental oxygen
as prescribed by a physician for the treatment of chronic pulmonary and
cardiovascular disease.

that will impair device performance and will void the warranty.

14
Wind or strong drafts can adversely affect accurate delivery
of oxygen therapy.
This device complies with Part15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) This device must accept any interference received,
including interference thatmaycause 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 of the Oxlife Liberty® including cables specified by
the manufacturer. Otherwise, degradation of the performance of this
equipment could result.
Use of accessories, transducers, or cables other than those specified by
O2 Concepts®could result in increased electromagnetic emissions or
decreased electromagnetic immunity ofthe device and result in improper
operation.
Use of the device adjacent to or stacked 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.
The device is suitable to use in a CISPR 11 Group 1 Class 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.
PRESCRIBED MODE AND FLOW SETTINGSSHOULD ONLY BE
ADJUSTED UNDER THE ADVICE OF A PHYSICIAN.
Outdoor use must be conducted using battery power.
Monitor children and pets when in proximity to the device.
Keep cannula tubing away 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 a damaged power cord or plug to avoid injury.
DO NOT operate the device on wet surfaces or in standing 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 (1.6 m) of the
oxygen concentrator or any oxygen carrying accessories.
Oxygen makes it easier for a fire to start 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
result infacial burns or death. 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 you are receiving the therapeutic amountof oxygen 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
physician for you atyour specific activity levels. The Oxlife Liberty®must be
used with the specific combination of parts and accessories that were used
while your settings were determined.
Replace cannula as recommended by the cannula manufacturer. 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.

basic safety with regard to the electromagnetic disturbances over the
expected service life.
DO NOT attempt to disassemble thebattery orpowersupply. Doingso will
void the warranty and may cause personal injury.
DO NOT use the battery 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 battery is
damaged, discontinue useanddispose of it properly to avoid personal injury.
DO NOT expose the battery towater orotherliquids. If battery gets wet,
discontinue use and dispose of it properly to avoid personal injury.
