2.3.5 Oxygen Concentration Test and Specification
To ensure that the unit’s output of oxygen is within specification, you must perform a test
of the oxygen concentration. Test the unit upon delivery to a patient, and at periodic
intervals. Equipment Providers need to establish and implement a protocol to check
oxygen concentration.
1.
If a humidifier bottle is used, disconnect it.
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. Allow approximately
five minutes for the oxygen concentration to stabilize. Take oxygen
concentration readings and verify levels are within specification at the liter flow
being tested.
5.
Disconnect the oxygen analyzer, and reconnect the humidifier bottle (if used).
Do not measure oxygen concentration output after the product stream
passes through a humidifier bottle, or erroneous readings will result.
