3.8 Daily system check for OAE devices
It is recommended to perform a daily check of your OAE equipment to ensure that it is in good working order,
before testing on patients. As the probe and probe tube often come into contact with wax or other debris in
the ear canal, a common fault affecting testing can be a blocked or partially obstructed probe tube. Running
a probe integrity test and a real-ear check allows for any probe faults or system distortions that can
masquerade as biological responses to be detected. A daily check ensures that you can be certain that the
results obtained throughout the day are valid.
3.8.1

Probe integrity test

The probe integrity test ensures artifact responses (system distortions) are not being generated by the probe
or hardware.
• The probe tube should be inspected for wax or debris prior to conducting the test.
Replace the probe tube if necessary before testing.
•
Testing should always be conducted in a quiet environment.
•
Test procedure:
1. Place a red flanged ear tip onto the probe tube and insert the probe into the
provided infant ear simulator.
2. Select an OAE test protocol. As system distortion is dependent on stimulus
output level, select a protocol that reflects what is used most often in clinical
practice.
3. Turn the OtoRead
RIGHT key until the green READY light goes off.
4. Allow the test to run until it stops automatically. Do not stop the test manually.
Test results:
If the probe is functioning correctly, none of the frequency bands (TEOAE) or points (DPOAE) should have a
checkmark, i.e, no artifacts/OAEs should be detected above the noise floor. The test result should be Refer.
Example of a refer result. There were no responses that matched the pass criteria.
