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. Your physician prescribed a flow or setting to address your particular respiratory condition. Although Oxygen is a non-additive 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 the prescribed flow rate.
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.
The FreeStyle Portable Oxygen Concentrator may be used during sleep under the recommendation of a qualified clinician.

What is the FreeStyle Portable Oxygen Concentrator? Oxygen concentrators were introduced in the mid-1970¶s and have 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 ³molecular sieve.´ This material separates the oxygen from the nitrogen. The result is a 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 and lightest portable oxygen concentrator at just 4.4 lb (2 kg). The FreeStyle efficiently produces its own oxygen, and quickly delivers it as a 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 the home. FreeStyle operates from four different power sources. (Refer to the Power Supplies section of this manual.)
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.

When the automobile in which you are using the FreeStyle unit 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 lowtemperature environments. (Refer to the Specifications section in this manual.)
If the unit has been stored for an extended period of time in a cold environment (outside its normal operating range), the unit should be allowed to warm up to ambient temperature before being turned on.
Federal (USA) law restricts this device to sale by order of a physician.
When using FreeStyle in an automobile, boat, or other vehicle with the DC power supply, make sure that the vehicle is started and running before connecting the FreeStyle unit. If the DC power supply does not illuminate and requires resetting, disconnect the DC power supply from the DC outlet, restart your vehicle, and then reconnect your DC power supply into the DC outlet.
Although FreeStyle is a low-voltage device, do not remove its housing. Only your Equipment Provider should remove the unit covers.
While using FreeStyle outside of its normal operating temperature range, there may be a decrease in battery performance or an increase in charge time.

Battery Charging Check to make sure your unit¶s battery is fully charged before venturing out with FreeStyle for the first time or upon subsequent use. To check the level of charge of the internal battery, press the BATT button on FreeStyle¶s keypad. The battery gauge/indicator(s) LEDs above the BATT button illuminate to indicate the level of internal battery charge (25-100%). Note: The internal battery is charging whenever the unit is operating on AC or DC power. To charge FreeStyle¶s internal battery, simply connect its AC power supply or DC power supply into the unit¶s power connection inlet (as shown in Figure 7). Be certain to first properly align the power cord to this inlet. To do this, take note of the ³D´-shaped plug of both the power cord connector and the FreeStyle¶s inlet connection. These must be properly aligned and when removing the power cord, the release button must be pressed to remove it from the FreeStyle unit. This ensures that neither the unit nor the power accessories are damaged. FreeStyle unit¶s Power Inlet
Press to remove power cord.
Optional AirBelt The optional AirBelt, which can increase FreeStyle¶s total battery duration up to 10 hours, requires approximately 3 hours to completely charge when the external battery is fully depleted. To recharge AirBelt, connect its own AC power supply to the end of AirBelt¶s power cord (as shown in Figure 8), and the other end of the power supply into a proper AC power outlet. A separate battery gauge/indicator for checking the level of charge on the AirBelt¶s battery is located on this accessory¶s cord and functions exactly like the internal battery¶s indicator on the keypad.
Figure 7: Internal Battery Charging
• • • • •
Figure 8: AirBelt Battery Charging
The FreeStyle¶s internal battery will completely recharge from its fully depleted state in approximately 3 ½ hours, whether or not the unit is in use on AC or DC power. While charging a fully discharged battery, initially the 25% LED will start blinking rapidly for a few minutes, then start to blink at a slower rate every (1/2 second). The LED will continue to blink until 25% capacity is reached. The LED will then turn solid. Each of the four LEDs, 25% -100% , will blink as stated above, then turn solid when they reach their capacity. When all LEDs illuminate solid, the battery is fully charged and the LEDs will remain solid for a period of time, then all four LEDs will turn off.

Charging may take several minutes after connecting the power to initiate, depending on the battery¶s internal operating temperature. This is a normal condition and is intended for safe battery charging. This circumstance is more likely when the battery has been fully discharged.
The rechargeable battery that is used in the FreeStyle unit does not need to be fully depleted before recharging. It is recommended to charge the battery after each use.
When connected to AC or DC power, the unit¶s battery charges until it reaches full capacity, either while the unit is operating or turned off.
If the power supply remains connected when the internal battery is fully charged, the four LEDs will turn off after approximately one hour.
If the internal battery fully depletes and the FreeStyle unit shuts down, the unit cannot be restarted with the AirBelt. Should this occur, connect your FreeStyle 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 then be connected to provide additional run time.
Storing your AirBelt for extended periods of time at high temperatures or with a fully charged/completely discharged battery can degrade its overall battery life.

Operating Instructions 1. Locate and position the FreeStyle so that the air inlets and air outlets are not obstructed. 2. Power the unit from (a) the internal battery; (b) AirBelt; (c) DC outlet (i.e. automobile or motor boat); or (d) an AC outlet (i.e. normal household electric). (Refer to the Power Supplies section of this Patient Manual.)
It may be necessary to initially connect the AC or 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.
1. Connect your cannula to the oxygen outlet. 2. Lift the dust cover on the unit. 3. Turn the FreeStyle unit on by pressing 1, 2, or 3 button on the unit¶s keypad for the liter flow prescribed by your physician. The green LED above the button selected illuminates. Each time you turn on the FreeStyle unit, a brief alarm sounds. This indicates that FreeStyle is powered for use. 4. To change the pulse flow setting, press the appropriate button. After the automatic start-up mode, it is normal to hear a difference in sound as you change the settings. 5. To turn FreeStyle off, press the button corresponding to the pulse flow setting light that is illuminated. When FreeStyle senses inhalation, oxygen is supplied to you through your cannula. The time required to reach maximum oxygen concentration after turning on the FreeStyle unit is approximately two minutes.

Power Supplies FreeStyle can be powered in four different ways ± the internal battery, an AC power supply, 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 AC 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. AC Power Supply: An AC 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. W hen FreeStyle is operated with the AC power supply, power from the AC outlet powers the unit and recharges FreeStyle¶s battery simultaneously. 3. DC Power Supply: A DC power supply can be connected from the FreeStyle unit 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 battery simultaneously. 4. Optional AirBelt (External Battery Belt): FreeStyle can also be powered by an external battery belt. This belt can be worn around the waist, and when used in combination with a fully charged internal battery, supplies power to FreeStyle for up to 10 hours. The belt pack connects to the FreeStyle unit¶s power inlet, and it can be recharged by connecting it to the 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. Observe and connect the AirBelt to the FreeStyle unit before its internal battery discharges to 25% or less.
If the internal battery fully depletes and the FreeStyle unit shuts down, the unit cannot be restarted with the AirBelt. Should this occur, connect your FreeStyle 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 then be connected to provide additional run time.

Filters Air enters FreeStyle through an air intake filter located under the cover on the lower front of the oxygen concentrator. (See Figures 13 and 14.) This filter prevents dust and other large particles in the air from entering the unit. Before you operate FreeStyle, make sure this filter is clean and positioned correctly.
Figure 13: Removal of Air Intake Filter Cover
Figure 14: Removal of Filter from Filter Cover
Use only AirSep Part No. FI144-1 as the air intake filter for this unit.

Setting of the Flow Selector The FreeStyle unit has three pulse flow settings: 1, 2, and 3, providing flows equivalent to 1-3 LPM oxygen. Lift the dust cover on the unit¶s keypad, and press the 1, 2, or 3 button, which corresponds to the oxygen pulse flow that your physician has prescribed. (See Figures 15 and 16.)
Figure 15: Lifting Dust Cover on Keypad Display
Figure 16: Pressing Flow Selection Button
It is very important to select only the prescribed level of oxygen. Change the pulse flow selection only under the guidance of your physician.
MN123-1 rev B 01/10
16
Alarm/Light Indicators When the FreeStyle unit senses inhalation, a pulse of oxygen is sent through the nasal cannula. The green light above the selected pulse flow setting displays intermittently each time a breath is detected. Additionally, when the unit is operating on and simultaneously being charged through the AC or 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 this section of the manual. •
Start-Up A brief alarm sounds at start-up. FreeStyle begins to operate when the alarm stops.
•
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 to an 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 of battery charge is indicated by the battery gauge/indicator(s).
