OAE probe test

Probe performance is crucial to OAE test results. We recommend that you conduct a probe test at the
beginning of each day before starting to test on patients to ensure that the probe is functioning correctly.
Daily probe test
It is common practice to conduct a probe test at the beginning of each day before starting to test on patients
to ensure that the probe is functioning correctly.
• Before conducting the probe test, ensure that the probe tip is clean and free of wax and/or debris
Always conduct the probe test in a quiet test environment
•
Only use the recommend cavity for testing. Using a different type of cavity may not detect probe
•
faults
Refer to the Instructions for Use for further information about how to perform this daily probe
test.

Automated ABR patient preparation

6.4.1

General information

The Sera with ABRIS (automated ABR) collects electrical signals from the brain via electrodes which are
TM
placed on the baby. As these signals are very small, it is recommended that the baby be asleep or in a very
calm state for testing. The baby can stay in its crib, be placed on an examination table or be held by the
parent.
Ideally, show the electrodes and transducer to be used to the parent before testing and explain the following:
• The aim of the test is to screen the hearing organ for its functionality
The skin will be prepared before placing three electrodes
•
A transducer (probe, insert headphones or EarCups) will be used to deliver the sound to the ear
•
A soft clicking sound will be heard during the test
•
The baby is not required to do anything during the test as it is automated
•
• Crying, sucking and movement may result in a longer test time
Please note: All disposable supplies included with Sera
only been tested using disposables supplied by Sanibel Supply. Use of other supplies could alter the
behavior and results obtained with the device and are not recommended. Sanibel disposables are latex,
DEHP and BPA free and have been tested for bio-compatibility. Data sheets are available upon request.
6.4.2

Skin preparation

The skin should be clean and free of lotions or oils. If any greasy skin care products have been used where
the electrodes are to be placed, the lotion/oil should be carefully removed prior to placing the electrodes.
This removal procedure should be discussed with a qualified nurse or doctor.
The electrode sites can be prepared and cleaned in order to obtain lower skin impedances. For this purpose,
a large variety of skin preparation pastes/gels can be purchased. Please note that two different types of
electrode pastes/gels exist: One which is an abrasive gel (such as NuPrep) to abrade the skin and another
which is an electrically conductive paste.
