AirSep MN110-1 - Manual (Page 14)

2.3.9 General Malfunction
If a general malfunction of the LifeStyle unit occurs, a half-second alarm sounds
every half second, and the red
ALARM light turns on. When this occurs, oxygen
concentration is outside specifications. The patient should change to another source
of oxygen and contact the Equipment Provider.
2.4 Oxygen Concentration Test and Specification
To ensure that LifeStyle’s oxygen output is within specification, you must perform a test
of oxygen concentration. Test the unit upon delivery to a patient and at periodic inter-
vals. 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.
1. Connect LifeStyle to AC electrical power using only the AirSep-supplied AC
adapter (AirSep Part No.PW005) to a 100-250 volt, 50/60 Hz outlet.
(Note: Do not use the battery [AirSep Part No. BT007-1] to operate the
unit when measuring oxygen concentration.)
2. Turn on LifeStyle, and adjust the flow selector to any of 1 through 5 lpm
settings.
3. Remove the gross particle filter.
4. Activate the test mode by depressing the switch located in the hole labeled
“T,” next to the hour meter. The unit should produce a pulse dose of oxygen
equivalent to a continuous flow of 4 lpm at a rate of 18 breaths-per-minute
while in the test mode.
5. When the unit supplies a pulse dose of oxygen, the green PULSE light is on,
and you will be able to hear the pulse of oxygen. Verify that the pulse light is
turning on and that you can hear the pulse dose.
6. Allow LifeStyle to run for five minutes before recording the oxygen concen-
tration. Connect a calibrated Teledyne TED or equivalent to the oxygen
outlet on the unit. Turn on the analyzer, and record the concentration. The
concentration specification in test mode is 90%
±3%.
