Oxygen Concentration Test and Specification

To ensure that FreeStyle'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.
1. Connect the FreeStyle Oxygen Concentrator using an AirSep-supplied
Universal AC or / DC power supply only (AirSep Part No. PW017-1) to a
100-240 volt, 50/60 Hz electrical outlet.
Note Previous AC to DC power AirSep P/N PW010-1 can be used as well.
2. Turn unit on by pressing setting 2 on keypad.
3. Simultaneously press and hold settings 1 and 3 for 10 seconds. After 10
seconds, the alarm will sound and the LEDs above each flow setting will
illuminate verifying auto pulse mode.
4. Allow unit to warm – up for 5 minutes before recording oxygen
concentration.
5. Connect a calibrated oxygen analyzer to the oxygen outlet and record the
unit's concentration, a 12" tube is recommended. The specification in test
mode is 87% or higher.
