Screening can be performed when the baby is lying in a crib, in a car seat or is being held
by the screener or parent. The key is to make the baby comfortable and quiet for the
screening. Swaddling the baby in a blanket with the arms wrapped inside is
recommended. This will calm the baby and keep the baby from disconnecting the
electrode lead wires or insert earphone tubes during the screening (MB 11 Classic only).
Risk of choking.
Always keep eartips and similar small pieces out of reach of
the baby.
IMPORTANT NOTE:
All disposable supplies included with MB 11 are produced by
Sanibel Supply. The system has 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.
5.2.1.2 Acoustic Noise
Acoustic noise in the screening environment can be so loud that the low-level stimulus
delivered by the hearing screening system is overwhelmed by the background noise.
Acoustic noise can also awaken the baby causing less than optimal recording
conditions and artifacts that prolong the test time. Acoustic noise can lead to a
REFER
result even for a baby with normal hearing.
What can the screener do to reduce acoustic noise?
•
Find a location for the screening that is as quiet as possible, such as an
unoccupied patient or procedure room.
•
Close the door to the test room to reduce the acoustic noise from others walking
in the hallway who may be talking or pushing equipment that is noisy.
•
Be aware of “hidden” sources of acoustic noise, such as air conditioner vents,
motors from devices. Try to avoid them by moving as far away as possible.
•
Ask others in the test room to suspend talking and mute or turn off radios or TVs
while the test is being performed.
•
Ask parents to take other children out of the mother’s room during the test.
5.2.1.3 Electrical Noise & ABR
Electrical noise in the screening environment can cause high artifact levels and
generally noisy EEG, prolonging ABR test times and increasing the chance of a
REFER
result. Electrical noise issues can be very difficult to troubleshoot and avoid in
a hospital environment.
