Preparing the Patient for Testing with MB 11 Classic
5.2.3.1 General
At the time of purchase you chose your preferred style of acoustic transducer. If insert
earphones were selected you also chose your preferred ear coupling method, the
EarCups
or eartips. Both use single-use disposable supplies.
In case of re-use of the single-use disposable, you enhance
the risk of cross contamination!
The EarCup
TM
is an around-the-ear coupler that connects to the tubing of the insert
earphones using the EarCup
TM
black adapters at the end of the tubes. The EarCups
TM
adhere to
the skin around the baby’s ears.
The eartip is a small tip that is installed on the clear infant eartip adapter attached to
the tubing of the insert earphones. The eartip is inserted into the baby’s ear canal.
The sections below offer the following information (see Table 8):

5.2.3.2 Placing electrodes for ABR testing with MB 11 Classic (EarCups
TM
and eartips)
ABR recording requires placement of 3 electrodes. The ideal electrode positions are:
•
Center of the forehead at the hairline
•
Cheek (either side)
•
Nape of the neck
An alternate electrode montage can be used as seen below. However, the screening
time for the right ear may be prolonged when using this montage.
•
Center of the forehead at the hairline
•
Right mastoid
•
Left mastoid
Regardless of the electrode placement you choose, the skin at the electrode locations
must be cleaned with an electrode skin preparation product. Rub the product gently,
but briskly on the skin at each position.
