The ABR test
The ABR tests are identical, except for the dB level at which the tests are performed. The level is indicated by the name of
the tests:
ABR 30, ABR 35, ABR 40, and ABR 45.
Caution
•
Mobile phones, electrically controlled tables or desks and other such devices may issue noise that can influ-
ence ABR measurements and lead to false referrals. Make sure that you carry out testing away from such sources of
noise.
5.5.1
Starting the test
1. Place the electrodes on the patient to ensure that they have time to connect well to the skin, for instance while you
explain the test process to relatives. (See
Placing the electrodes for ABR testing
.)
2. Connect the electrode cable.
3. Fit the probe or the ear couplers with the ear coupler cable. The ABR display changes automatically.
4. Decide on which ear you wish to perform the test, and prepare the patient as described in
Testing one ear
•
To start the test, press the
Start
button that is next to the
ABR
test, and that
corresponds to the ear in which you placed the probe.
