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 fromsupplemental 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-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 operate the Focus

Portable Oxygen Concentrator.

What is the Focus Portable Oxygen Concentrator?
Oxygen concentrators were introduced in the mid-1970s 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 Focus unit, room air passes through aregenerative, adsorbent material called molecular sieve. This material separates the oxygen from the nitrogen. The result is a flow ofhigh-concentration oxygen delivered to the patient.
Focus combines advanced oxygen concentrator technology with oxygen conserving technology for the world’s smallest and lightest
portable oxygen concentrator at just 1.75 lb (0.8 kg). The unit efficiently produces its own oxygen, and quickly delivers it as a pulseof oxygen at the very beginning of your inhalation. This eliminates the waste associated with a continuous flow oxygen device thatdelivers oxygen even while you are exhaling. Focus produces the equivalent of 2 LPM (liters per minute) continuous flow oxygen ina lightweight package that patients can wear easily away from the home.
Focus 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
affect the efficiency of ones lungs to transfer the oxygen in air to their bloodstream. POC’s provide the convenience of using a nondelivery 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 disease (COPD). Patients typically have good cognitive abilities and must
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 otherunique skills or user abilities required for concentrator use.

Focus for Airline Travel – FAA-Approved
Focus has received the US Federal Aviation Administration’s (FAA) acceptance for onboard in-flight use by oxygen passengers
on commercial airlines via a 2012 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 withwhich you would like to travel for up-to-date information on their specific POC policies.

2. Depending upon the temperature of the AirBelt, it can take several minutes for the charging cycle tostart after connecting to power. This is a normal condition and is intended for safe charging.

For oxygen concentrators equipped with the optional Airbelt:
1. If the AirBelt power supply remains connected when AirBelt is fully charged, the four LEDs will turn off within 15
minutes.
2. Lithium batteries may permanently lose capacity when exposed to extremely hot temperatures with thebatteries fully charged or completely depleted. For extended storage, it is recommended that batteries becharged 25 to 50% and remain within a temperature range of 73°F +/- 35°F (23°C +/- 2°C).

Nasal Cannula
A nasal cannula with tubing are used to deliver oxygen from the Focus unit to the user. The tubing is connected to the unit’s
oxygen outlet (See Figure 18).
Focus Power Inlet
Connect the Cannula to
Focus’s Oxygen Outlet

Figure: 18

AirSep recommends a nasal cannula with 7 ft (2.1 m) of tubing, AirSep Part No. CU002-1, or other suitable cannula. Other
lengths of non-kinking/star channel cannula can be used for a total length of up to 25 ft (7.6 m) maximum.
When Focus is operating but does not sense breathing for 15 minutes, a constant alarm sounds, and the amber alarm lightilluminates simultaneously. If this occurs, check the connection from the cannula to the Focus unit, make sure that the nasal
cannula is positioned properly on your face, and ensure that you are breathing through your nose. (Your physician may
recommend the use of a chin strap if needed.) If the alarm condition continues, change to another source of oxygen as available,
and contact your Equipment Provider.

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 ofthe nasal cannula.
Always follow the cannula manufacturer’s instructions for proper use. Replace the disposable cannula asrecommended by the cannula manufacturer or your Equipment Provider. Additional supplies are available
from your Equipment Provider.
Cannula tubing must be non-kinking, which can be used for a total length of up to 25 ft (7.6 m) maximum

Operating Instructions
1. Locate and position Focus so that the air inlet and outlet are not obstructed.
2. Power the unit from (a) the battery; (b) DC outlet (i.e. automobile or motor boat); or (c) an AC outlet (i.e. normal household
electric). (Refer to the Power Supplies section of this Patient Manual.
(Refer to Connecting to Focus’s Power Inlet section for specific instructions on the connection of power sources.)
3. Securely connect your cannula to the oxygen outlet, as shown in Figure 18.
Use no oil, grease, or petroleum-based or other flammable products with the oxygen-carrying accessories or
the Oxygen Concentrator. Only water based, oxygen compatible lotions or salves should be used. Oxygen
accelerates the combustion of flammable substances.

Power Supplies (Overview)
Focus can be powered in four different ways – the battery, AC power, DC power, or an optional AirBelt. The Focus power supply
functions both as an AC power supply and a DC power supply.
(Refer to Connecting to Focus’s Power Inlet section for specific instructions regarding the connection of optional
power sources.)• Battery: Two rechargeable batteries are supplied with Focus. Each battery, when fully charged, supplies power to the Focus
unit for up to 1 ½ hours. An audible alarm sounds when the battery power is getting low. The alarm is discussed in the
Audible Alarm and Indicator Lights section of this manual. The 25% capacity LED will blink every ½ second to indicate alow state of charge when the button is pressed.

During this condition, change to another battery or alternate power source.

 Battery Charging (Battery Charging section): To charge the battery, connect the battery to either the power supply and a
100-240 volt, 50/60 Hz AC power outlet, or connect the power supply to a DC power outlet in an automobile (boat, motor
home, etc.). A discharged battery requires approximately four hours to fully charge. It is recommended to recharge thebattery, even if only partially depleted, as often as possible.
• Universal Power Supply
 The AC power supply side of the universal power supply, allows the Focus unit to connect to a 100-240 volt, 50/60 Hz
outlet. The power supply converts 100-240 volt AC to a DC voltage for the Focus unit to operate while recharging the
Focus battery simultaneously.
 The DC power inlet on the universal power supply, allows the Focus unit to connect to a motor vehicle’s 12-Volt DC
outlet for the Focus unit to operate while recharging Focus’s battery simultaneously.
• Optional AirBelt: Focus can also be powered with AirBelt. AirBelt can be worn around the waist. When fully charged, thebattery supplies power to Focus for up to 4 hours. AirBelt connects to the Focus unit’s power inlet. It can be recharged byconnecting it only to the AirBelt AC power supply.

[Read the Important Safety Rules section before operating this equipment]

Audible Alarm and Indicator Lights
When the Focus unit senses inhalation, a pulse of oxygen is delivered through the nasal cannula. The green light on the unit’s
control panel blinks each time a breath is detected.
Additionally, when the unit is operating and the battery is simultaneously being charged through the Universal AC / DC power
supply, the battery for the Focus unit will display the charge level of the battery (25% to 100% state of charge) on the battery
gauge/indicator(s) and when at 100%, LEDs (lights) remain on for approximately 15 minutes after reaching a full charge.
An audible alarm sounds if Focus has a low battery, if the cannula is disconnected, or if performance of the unit is outside of
specifications. The light and audible alarm conditions are explained in detail below and summarized on the chart later in thissection of the manual.
•Start-UpA brief alarm sounds and the green and red LEDs (lights) will alternate at start-up. Focus begins to operate when thealternating LEDs (light) stop and green LED (lights) remains on.

•

Low Battery
 Focus unit indicators: As the battery power approaches a low level, the amber light on the Focus unit will flash on for½ second with a 5-second pause and simultaneously, a ½ second alarm sounds with a 5-second pause. Following thebattery warning indicators, if action is not taken, the unit will shut down. This will be indicated when the amber light
flashes 2 times with a 5-second pause and simultaneously, a ½ second alarm sounds 2 times with a 5 second pause.
 Battery indicator: The green light indicator on the battery gauge (Figure 9) light illuminates intermittently.
When either of these conditions occurs, connect Focus to a DC power outlet or to an AC power outlet, or change to anothersource of oxygen within two minutes. The level of battery charge is indicated by the battery gauge/indicator(s). You canalso check the state of charge at any time by pressing the button.
As noted above, when the unit is connected to AC or DC power outlet, you may simultaneously charge the Focus battery
supplied with the unit while using the unit.

In the event of an alarm or you observe Focus is not working properly; consult the Troubleshooting section in thismanual. If you cannot resolve the problem, consult your Equipment Provider.
