General information

The Sera with DPOAE and TEOAE records otoacoustic emissions emitted by the outer hair cells, located
TM
in the cochlea. 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 probe to the parent before testing and explain the following:
• The aim of the test is to screen the hearing organ for its functionality
A transducer (probe) 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 is not recommended. Sanibel disposables are latex, DEHP
and BPA free and have been tested for bio-compatibility. Data sheets are available upon request.

Sera™ - Additional Information
Do not insert the probe tip into the patient's ear canal without a disposable
ear tip attached.
Choose the appropriate size of ear tip based on your inspection of the size
of the baby's ear canals (Figure 10). The Sanibel green Preemie and the
red flanged ear tip fits most newborn ears. Other sizes are available for
larger ear canals.
Place the ear tip onto the probe tip.
Insert the probe with ear tip attached into the baby's first test ear. Do this
by pulling gently down and out on the baby's ear lobe to open up the ear
canal. Hold the probe, aim and gently twist the ear tip into the ear
canal.The fit of the ear tip should be secure; not superficial. Release the
earlobe. You should not hold the probe during the measurement as this
can produce excessive noise in the recording, prolonging the test time.
