Why Your Physician Prescribed Oxygen
Many people suffer from a variety of heart, lung, and other respiratory diseases. A significant number of these patients can benefit
from supplemental oxygen therapy at home, when traveling, or while participating in daily activities away from home.
Oxygen is a gas that makes up 21% of the room air we breathe. Our bodies depend on a steady supply to function properly. Yourphysician prescribed a flow or setting to address your particular respiratory condition.
Although Oxygen is a non-addictive drug, unauthorized oxygen therapy can be dangerous. You must seek medical advice before you
use this oxygen concentrator. The Equipment Provider who supplies your oxygen equipment will demonstrate how to set theprescribed flow rate.

What is the FreeStyle Portable Oxygen Concentrator?
Oxygen concentrators were introduced in the mid-1970’s and has become the most convenient, reliable source of supplemental oxygen
available today. Oxygen concentrators are the most cost-effective, efficient, and safest alternative to using high-pressure oxygen
cylinders or liquid oxygen. An oxygen concentrator provides all the oxygen you need with no cylinder or bottle deliveries required.
The air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% other gases. In the FreeStyle unit, room air passes
through a regenerative, adsorbent material called “molecular sieve.” This material separates the oxygen from the nitrogen. The result isa flow of high-concentration oxygen delivered to the patient.
FreeStyle combines advanced oxygen concentrator technology along with oxygen conserving technology for the world’s smallest andlightest portable oxygen concentrator at just 4.4 lb (2 kg). The FreeStyle efficiently produces its own oxygen, and quickly delivers it asa pulse of oxygen when you breathe at the very beginning of your inhalation. This eliminates the waste associated with a continuous
flow oxygen device that flows oxygen while you are exhaling. This pulsing of the oxygen is equivalent to continuous flow. FreeStyle
produces the equivalent of up to 3 LPM (liters per minute) in a lightweight package that can be easily carried and used away from thehome.
FreeStyle operates from four different power sources. (Refer to the Power Supplies section of this manual.)

Operator Profile:
AirSep’s Concentrators are intended to supply supplemental Oxygen to users suffering from discomfort due to ailments which
effect the efficiency of ones lungs to transfer the oxygen in air to their bloodstream. POC’s provide the convenience of using a
non-delivery POC system rather than delivery system (O2 tank) which makes the user relatively self-sufficient in terms of in-home use,
ambulation (both within and outside of the home) mobility and overall lifestyle. Oxygen Concentrator use requires a physician’sprescription, and is not intended for life support use.
Although Oxygen therapy can be prescribed for patients of all ages the typical oxygen therapy patient is older than 65 years ofage and suffers from Chronic Obstructive Pulmonary Disorder (COPD). Patients typically have good cognitive abilities andmust be able to communicate discomfort. If the user is unable to communicate discomfort, or unable to read and understand theconcentrator labeling and instructions for use, then use is recommended only under the supervision of one who can. If any
discomfort is felt while using the concentrator, patients are advised to contact their healthcare provider. Patients are also
advised to have back-up oxygen available (i.e. cylinder oxygen) in the event of a power outage or concentrator failure. There
are no other unique skills or user abilities required for concentrator use.

FreeStyle for Airline Travel – FAA-Approved
FreeStyle has received the US Federal Aviation Administration’s (FAA) acceptance for onboard in-flight use by oxygen
passengers on commercial airlines via a 2006 amendment to SFAR 106.
In addition, as of May 13, 2009, a new Department of Transporation (DOT)/FAA ruling has determined that US-based carriers,
as well as international flights with origination or destination in the US, must allow passengers with FAA-approved portable
oxygen concentrators to use them on board, and in flight, as medically necessary. Check directly with the individual airlines
with which you would like to travel for up-to-date information on their specific POC policies.

Operating outside of the operational specifications can limit the concentrator's ability to meet Oxygen Concentration
specification. Refer to the specifications section of this manual for storage and operating temperature limits.
The Oxygen Concentrator should not be used adjacent to or stacked with other equipment. If adjacent or stacked use isunavoidable, the device should be observed to verify normal operation.
No modification of this equipment is permitted.
Use of cables and adapters other than those specified, with the exception of cables and adapters sold by the
manufacturer of the medical electrical equipment as replacement parts for internal components, may result in increased
emissions of decreased immunity of the Oxygen Concentrator.
Use only electrical voltage specified on the specification label affixed to the device.
Do not use extension cords with this unit or connect too many plugs into the same electrical outlet. The use of extension
cords could adversely affect the performance of the device. Too many plugs into one outlet can result in an overload tothe electrical panel causing the breaker/fuse to activate or fire if the breaker or fuse fails to operate.
This unit is not to be used for life support. Geriatric, pediatric, or any other patient unable to communicate discomfort while
using this device may require additional monitoring. Patients with hearing and/or sight impairment(s) may need assistancewith monitoring alarms.
Pulse Dose Node settings must be determined for each patient individually for their needs at rest, during exercise, andwhen traveling.
If you feel discomfort or are experiencing a medical emergency, seek medical assistance immediately.
It may be necessary to initially connect the Universal AC/DC FreeStyle power supply to the FreeStyle unit before the unit
will operate for the first time on battery power. Your Equipment Provider may have already performed this step for you.
Each time the FreeStyle unit is turned on; it cycles through an automatic start-up period for approximately seven minutes.
During this time, it maintains a constant speed regardless of setting. After this period, it is normal to hear a change in
speed at the 1 and 2 settings. This variation in sound represents the differences in oxygen production the unit makes at
each setting.
Ensure the cannula is fully inserted and secure. This ensures that the Oxygen Concentrator can properly detect
inspiration for oxygen delivery. During inhalation, you should hear or feel oxygen flow to the prongs of the nasal cannula.
Always follow the cannula manufacturer’s instructions for proper use. Replace the disposable cannula as recommended
by the cannula manufacturer or your Equipment Provider. Additional supplies are available from your Equipment Provider.

Power Supplies
FreeStyle can be powered in four different ways – the internal battery, a Universal AC/DC power supply and an optional AirBelt
battery belt in combination with the unit’s internal battery.
1. Internal Battery: A rechargeable internal battery is located within each FreeStyle unit. When it is fully charged, it
supplies power to the FreeStyle unit for up to 3 ½ hours. An audible alarm sounds when the battery power is getting low.
The alarm is discussed in the Alarm/Light Indicators section of this manual.
Battery Charging: To charge the internal battery, connect FreeStyle to either the Universal AC/DC power supply and a
100-240 volt, 50/60 Hz AC power outlet, or connect it to a DC power outlet in an automobile (boat, motor home, etc.). A
discharged battery requires approximately 3 ½ hours to fully charge. It is recommended to recharge the battery, even if
only partially depleted, as often as possible.
2. Universal AC/DC Power Supply: A Universal AC/DC power supply allows FreeStyle to be connected to a 100-240
volt, 50/60 Hz outlet. The power supply converts 100-240 volt AC to a DC voltage for the FreeStyle unit. When
FreeStyle is operated with the Universal AC/DC power supply, power from the AC outlet powers the unit and recharges
FreeStyle’s battery simultaneously.
3. Optional AirBelt (External Battery Belt): FreeStyle can also be powered by an external battery belt. This belt can beworn around the waist, and when used in combination with a fully charged internal battery, supplies power to FreeStylefor up to 10 hours. The belt pack connects to the FreeStyle unit’s power inlet, and it can be recharged by connecting it tothe battery belt’s own AC power supply.
When using the AirBelt with a fully charged internal battery, the FreeStyle’s internal battery will deplete before the
AirBelt. The AirBelt must be connected to the FreeStyle unit before the FreeStyle’s internal battery is depleted. Observeand connect the AirBelt to the FreeStyle unit before its internal battery discharges to 25% or less.
For oxygen concentrators equipped with batteries:
1. When connected to AC or DC power, the unit’s battery charges until it reaches full capacity, either while theunit is operating or turned off.
2. If the internal battery fully depletes and the Oxygen Concentrator shuts down, the unit cannot be restarted
with the optional AirBelt. Should this occur, connect your Oxygen Concentrator to its AC or DC power supply
for a short period of time in order to provide sufficient internal battery power to start the unit. AirBelt can thenbe connected to provide additional run time.

Alarm/Light Indicators
When the FreeStyle unit senses inhalation, a pulse of oxygen is sent through the nasal cannula. The green light above theselected pulse flow setting displays intermittently each time a breath is detected.
Additionally, when the unit is operating on and simultaneously being charged through the Universal AC/DC power supply, the
FreeStyle unit’s battery gauge/indicator(s) display the charge level of the battery and remain on for approximately one hour after
reaching a full charge.
An audible alarm sounds if FreeStyle has a low battery, if the cannula is disconnected, or if performance of the unit is outside
specifications. The light and audible alarm conditions are explained in detail below and summarized on the chart later in thissection of the manual.
This unit is not to be used for life support. Geriatric, pediatric, or any other patient unable to communicate discomfort while
using this device may require additional monitoring. Patients with hearing and/or sight impairment(s) may need assistancewith monitoring alarms.
Pulse Dose Node settings must be determined for each patient individually for their needs at rest, during exercise, andwhen traveling.
If you feel discomfort or are experiencing a medical emergency, seek medical assistance immediately.
In the event of an alarm or you observe FreeStyle is not working properly; consult the Troubleshooting section in thismanual. If you cannot resolve the problem, consult your Equipment Provider.

o Start-Up
A brief alarm sounds at start-up. FreeStyle begins to operate when the alarm stops.
o Low Battery
As the battery power approaches a low level, a brief alarm sounds intermittently, and the yellow 25% Battery gauge /indicator (Figure 11) light also illuminates intermittently. When this occurs, connect FreeStyle to a DC power outlet or toan AC power outlet, or change to another source of oxygen within two minutes. When FreeStyle is connected to DC
power outlet or AC power outlet, the unit operates while recharging FreeStyle’s battery simultaneously. The level ofbattery charge is indicated by the battery gauge/indicator(s).
