2.4 Oxygen Concentration Test and Specification
To ensure that the unit’s output of oxygen is within specification, you
must perform a test of oxygen concentration. Test the unit upon delivery
to a patient and at periodic intervals. Equipment Providers, based on
their 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, which is AirSep’s default time
period for providers who do not choose to establish their own protocol.
1 If an oxygen humidifier bottle is used, remove it from the oxygen
outlet.
2 Connect a calibrated oxygen concentration analyzer to the oxygen
outlet.
3 Verify that the product flow rate delivered by the unit matches the
patient’s prescription and does not exceed the capacity of the unit.
4 Set the unit’s ON/OFF power switch to the ON position. (It takes
approximately five minutes for the oxygen concentration to
stabilize.) Take oxygen concentration readings every 60 seconds
until the analyzer shows that two consecutive readings are the
same.
5 Disconnect the oxygen analyzer, and reconnect the humidifier
bottle (if used) and any other equipment/ accessories that may be
required.
6 Adjust the flowmeter adjustment knob to the prescribed level.
NOTE
Do not measure oxygen concentration output
after the product stream passes through a
humidifier bottle, or erroneous readings will
result.
