MN171-1 Rev. A 02/14
4.6 Performance Warning
The performance of Focus can be affected by two conditions.
1) If the user’s breathing rate causes the Focus unit’s capacity
to be exceeded.
2) The second condition that can result in decreased performance is a
general malfunction (i.e. High temperature, High or Low pressure).
4.6.1 Focus Capacity Exceeded
When the patient’s breathing rate has caused the capacity of Focus to be exceeded, an alarm
sounds 3 times every ½ second with a 5 second pause, and the amber alarm light illuminates
simultaneously (See Table 1).
When this occurs, the concentration of oxygen that Focus is supplying is outside of the unit
specifications. The patient is advised to reduce any physical activity, reset alarm by turning unit
off and back on, and then if necessary change to another source of oxygen as available, and
contact your Equipment Provider
4.6.2 General Malfunction
If Focus has a general malfunction, an audible alarm sounds and the red alarm light illuminates
(See Table 1).
If this alarm condition occurs, the patient is advised to change to another source of oxygen as
available, and contact your Equipment Provider
5.0 Oxygen Concentration Test and Specification
To ensure that Focus’s oxygen output is within specification, you must
perform an oxygen concentration test. Test the unit upon delivery to a
patient and at periodic intervals. Equipment Providers, based upon their
own expertise and documentation, may establish and implement their own
protocol to check oxygen concentration. The interval established may be
longer or shorter than 90 days, AirSep’s default time period for providers
who do not choose to establish their own protocol.
5.1. Connect the Focus Oxygen Concentrator to an AirSep-supplied AC power supply (AirSep Part
No. PW019-1).
5.2. To activate the unit’s test mode:
5.2.1 Focus unit off before 4 seconds expires.
5.2.2 Turn the unit on and then off again during the 10 second start up sequence. The user has a
maximum of 6 seconds to complete this task.
5.2.3 Repeat step 5.2.2
5.2.4 Turn the unit on and let it remain on.
5.3. Verify Focus is pulsing by observing the intermittent green LED.
