What is the Focus Portable Oxygen Concentrator? Oxygen concentrators were introduced in the mid-1970s and have become the most convenient, reliable source of savailable today. Oxygen concentrators are the most cost-effective, efficient, and safest alternative to using hicylinders or liquid oxygen. An oxygen concentrator provides all the oxygen you need with no cylinder or bottle delThe air we breathe contains approximately 21% oxygen, 78% nitrogen, and 1% other gases. In the Focus unit, room a regenerative, adsorbent material called molecular sieve. This material separates the oxygen from the nitrogen. Th

high-concentration oxygen delivered to the patient. 

Focus combines advanced oxygen concentrator technology with oxygen conserving technology for the world’s smaportable oxygen concentrator at just 1.75 lb (0.8 kg). The unit efficiently produces its own oxygen, and quickly deliof oxygen at the very beginning of your inhalation. This eliminates the waste associated with a continuous flow ox

delivers oxygen even while you are exhaling. Focus produces the equivalent of 2 LPM (liters per minute) continuin a 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.)

Before operating Focus for the first time, familiarize yourself with the major components. These are illustratethe following pages and discussed later in the manual.Connecting to the Focus Power Inlet:Locate the arrow marking at the top of the connector. Insert connector (Figure 5) into the Focus power inlet arrow on the side of the connector facing outward. Do not force the connector into the power inlet, as it can bway. This ensures that neither the unit nor the power accessories are damaged. Focus operates from four different power sources. NOTE: Always connect to the Focus power inlet first before connecting to a power supply. 1) Connecting Focus to AC electrical power:

 When you are near an AC outlet, you may choose to operate Focus with the universal power supply rather t

 Connect the cord on the power supply labeled as DC OUT To Focus into the Focus unit’s power inlet,  as shown in Figure 7. Do not force the plug, as it should be inserted only one way.  From the other end of the power supply, connect the 3-prong AC cord from the power supply into any stand

Nasal Cannula 

A nasal cannula with tubing are used to deliver oxygen from the Focus unit to the user. The tubing is connoxygen outlet (See Figure 18). 

AirSep recommends a nasal cannula with 7 ft (2.1 m) of tubing, AirSep Part No. CU002-1, or other suitable c

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 

illuminates simultaneously. If this occurs, check the connection from the cannula to the Focus unit, make sure cannula is positioned properly on your face, and ensure that you are breathing through your nose. (Your physirecommend the use of a chin strap if needed.) If the alarm condition continues, change to another source of ox

Power Supplies (Overview) Focus can be powered in four different ways – the battery, AC power, DC power, or an optional AirBeltsupply 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 connectio

power sources.) 

 Battery: Two rechargeable batteries are supplied with Focus. Each battery, when fully charged, sup

Focus unit for up to 1 1⁄2 hours. An audible alarm sounds when the battery power is getting low. The althe Audible Alarm and Indicator Lights section of this manual. The 25% capacity LED will blink 

indicate a low 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 

a 100-240 volt, 50/60 Hz AC power outlet, or connect the power supply to a DC power outlet in an motor home, etc.). A discharged battery requires approximately four hours to fully charge. It irecharge the battery, 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-

outlet. The power supply converts 100-240 volt AC to a DC voltage for the Focus unit to operate wFocus battery simultaneously. 

 The DC power inlet on the universal power supply, allows the Focus unit to connect to a motor ve

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. W

the battery supplies power to Focus for up to 3 1⁄2 hours. AirBelt connects to the Focus unit’s powrecharged by connecting it only to the AirBelt AC power supply.
