Oxygenis a gas that makesup 21% of the roomair we breathe. Our bodies dependon a steady supply tofunction
properly. Yourphysician has prescribed supplemental oxygen therapy because your body is not able to get enough
oxygenfromroom air. Oxygenisanon-addictivedrug,and yourphysicianprescribedaflowsufficienttoimproveyour

Pleasekeep in mind that unauthorized oxygen therapycanbedangerous. Youmustseekmedical advice before you

It is very important to select the prescribed level of oxygen flow. Do not increase or decrease the flow
until you first consult your physician.

What Is the FreeStyle Portable Oxygen Concentrator?
Oxygenconcentrators were introduced in themid-1970sandhavebecome the most convenient, reliablesourceof
supplementaloxygen available today.Oxygenconcentratorsare the cost-effective,efficient,and safe alternativeto
usinghigh-pressure oxygen cylinders orliquidoxygen. Anoxygen concentrator provides all theoxygenyou need
withno cylinderorbottle deliveriesrequired.
Theair we breathe contains approximately 21% oxygen, 78% nitrogen,and1%othergases.In the FreeStyle unit,
roomairpasses through a regenerative, adsorbent material called "molecular sieve." This materialseparatesthe
oxygenfrom thenitrogen.The resultisa flowofhigh concentrationoxygendelivered tothepatient.
Thesize and weight of traditionaloxygenconcentratorshave limited their portability.Apersonwho needs oxygen
awayfrom home or a hospital has used high-pressure oxygencylindersand/orliquidoxygen.Oxygen conserving
devices(OCDs) have been used to increase the length oftimethatcylinderslast.OCDs deliver oxygen only at the
beginningofinhalation,whenoxygenis mostbeneficial. Using thistechnique, OCDsconserveoxygen.
FreeStyleusestraditionaloxygenconcentrationtechnologyandcombinesitwithoxygenconservingtechnology.This
combinationenablesasignificantreductioninthesizeoftheoxygen concentratorandmakesFreeStyleultra-portable.
Atypical oxygen concentrator weighs more than 50pounds.Incontrast,your FreeStyle concentrator weighs only
4.4lbs (2kg).

thatcanbe easily carried and used away from home.
FreeStyleoperates from four different power sources. (RefertothePower Supplies section of this manual.)

Important Safety Rules
Carefullyreviewand familiarizeyourself withthefollowingimportantsafetyinformationabouttheportableFreeStyle
OxygenConcentrator.
Inthe eventof analarmor ifyouare experiencinganysigns ofdiscomfort,consult yourEquipment
Providerand/oryourphysicianimmediately.
This unit is not to be used for life support. Geriatric, pediatric, or any other patients unable to
communicatediscomfortwhileusingthis machinemay requireadditional monitoring.Patients with
hearingand/orsightimpairment(s)may needassistance withmonitoring alarms.
Whenusing FreeStylein an automobile,boat, or other vehicle with theDC power supply,make
surethatthevehicleisstartedand runningbefore connectingthe FreeStyleunit. If theFreeStyle unit
isconnectedtothevehiclewhile starting it, jumping or charging the vehicle may cause a need to
resettheFreeStyleunit's DC power supply. Ifthisoccurs,disconnecttheDCpowersupplyfrom
theDCoutlet, restart your vehicle, and then reconnect your DC power supply intotheDCoutlet.

Never use FreeStyle with the device itself located in the trunk of an automobile.
Do not allow either the air intake filter or the air outlets to become blocked during use.
When the automobile in which you are using FreeStyle is turned off, disconnect and remove the unit
from the automobile with you. Never allow FreeStyle to be stored in a very hot automobile or in other
similar, high- or low-temperature environments. (Refer to the Specifications section in this manual.)
Do not leave a nasal cannula under bed coverings or chair cushions. If FreeStyle is turned on but not
in use, the oxygen could make the material flammable. Make sure FreeStyle is off when not in use.
Although FreeStyle is a low-voltage device, do not remove its housing. Only your Equipment Provider
should remove the unit covers.

AirSep recommends an alternate source of supplemental oxygen in the event of a power outage,
alarm condition, or mechanical failure. Consult your physician or Equipment Provider for the type of
reserve system required.
Federal (USA) law restricts this device to sale by order of a physician. Use FreeStyle in accordance
with AirSep’s FreeStyle Patient Manual.

Power Supplies
FreeStylecanbe powered infourdifferentways – theinternalbattery,anACpower supply,DCpowersupply,and an
optionalAirBeltbattery beltincombinationwiththeunit’sinternalbattery.
1. InternalBattery:Arechargeable, internalbatteryislocatedwithin eachFreeStyleunit.When itisfully
charged,it suppliespowertothe FreeStyleunit for up to3½hours.Anaudible alarm sounds when the
batterypowerisgettinglow.Thealarmisdiscussedin theAlarm/LightIndicatorssectionofthismanual.
BatteryCharging:Tocharge the internal battery, connect FreeStyletoeither theAC power supply
and a 100-240 volt, 50/60 HzAC power outlet, or connect it to a DC power outlet in an automobile
(boat,motor home, etc.). It takes a minimum of31/2hours for a discharged battery to fullycharge. It
isrecommended to rechargethebattery,even if only partially depleted, asoftenaspossible.
2. ACPowerSupply:AnAC power supply allowsFreeStyleto be connected toa 100-240 volt, 50/60
Hzoutlet.The power supply converts 100-240 voltAC to a DC voltage for theFreeStyleunit.When
FreeStyleisoperatedwiththeACpowersupply,power fromtheACoutlet powersthe unitand recharges
FreeStyle’sbatterysimultaneously.
3. DCPowerSupply:ADCpowersupplycanbeconnectedfromtheFreeStyleunit to an automobile's
(boat, motor home, etc.) 12-volt DC outlet. When FreeStyle is connected to the automobile’s DC
outlet, power from the automobile battery powers the FreeStyle unit and recharges the FreeStyle’s
batterysimultaneously.
4. OptionalAirBelt (ExternalBattery Belt): FreeStyle can also be powered by an external battery
belt. Thisbeltcanbewornaround thewaist, andwhen usedincombinationwithafullycharged internal
battery,supplies power to FreeStylefor up to 10 hours. The belt pack connects to the FreeStyleunit's
powerinlet,anditcanberechargedby connecting it to the battery belt's own power supply.
