AccuScreen OAE & ABR Screener • User Manual

Otometrics 9
1 Introduction
Thank you for purchasing the AccuScreen handheld Otoacoustic Emissions and
Automated ABR Screener.
Note · This manual is your guide to the use and maintenance of AccuScreen. We strongly
recommend that you read it carefully before using AccuScreen for the first time.
We also recommend that you take particular note of the cleaning and maintenance
instructions. Failure to use and maintain AccuScreen correctly may void your war-
ranty.
AccuScreen is a fast, reliable, easy to use, and lightweight hearing screener, optimised
for neonatal screening. AccuScreen closes the gap between electrophysiological
assessment, which is time-consuming and expensive, and behavioral observation.
AccuScreen provides for easy navigation using its touch screen function.
AccuScreen uses TEOAE (Transiently Evoked Otoacoustic Emissions) and DPOAE
(Distortion Product Otoacoustic Emissions) technologies, which are highly effective
for neonatal hearing screening. Otoacoustic Emissions measure cochlear mechanics
and indicate whether the cochlea is functioning correctly or not. Children's emis-
sions are typically strong, which makes them easy and fast to detect. Emission
strength usually decreases with age.
Automated ABR (Auditory Brainstem Response) is also available in AccuScreen. This
technology measures responses to sound in the auditory pathways. It provides a valu-
able supplement to TEOAE and DPOAE screening, and is an essential tool for
screening infants with a risk of hearing loss.
The simple yet reliable technology ensures that hearing loss can be detected and that
intervention can be implemented at an early age. With early intervention, hearing-
impaired children are given the possibility of developing normal speech and language
skills.

Introduction
The different versions of AccuScreen
1.1 The different versions of AccuScreen
AccuScreen is available in different configurations.
You can choose between the following types and test methods:
1.2 The AccuScreen docking station
The AccuScreen is supplied with a docking station, which provides for:
• easy recharging of the battery
• transferring data between device and PC
• printing from a label printer
• transferring data via modem
1.3 The AccuLink software program
AccuLink is a software program providing data management handling with result
review and configuration capabilities in a single PC application.
From AccuLink you can create, edit, view and print data relating to patients and tests,
users, sites and connected locations and facilities.
From AccuLink you can configure AccuScreen to suit your purposes. This includes
defining mandatory fields in patient handling, defining which screens are to be
shown in AccuScreen, and uploading and downloading data.
AccuScreen is operated independently of AccuLink, although additional features and
configuration value are offered by AccuLink’s user interface.

AccuScreen
With AccuScreen you can upload data to AccuLink and print test results from the
AccuLink PC, or you can place AccuScreen in the docking station and print directly
to a label printer connected to the docking station.
1.5 Intended Use
AccuScreen is a portable instrument used to screen infants for hearing loss. The
instrument uses the Distortion Product Otoacoustic Emissions (DPOAE), Transient
Evoked Otoacoustic Emissions (TEOAE) and Auditory Brainstem Response (ABR)
technologies.
The instrument is intended for screening infants from 34 weeks (gestational age) up
to 6 months of age that are well enough to be ready for discharge from the hospital.
Infants should be asleep or in a quiet state at the time of screening.
AccuScreen is intended for use by audiologists, ENTs and other health care profes-
sionals.
Important · GN Otometrics A/S does not guarantee the accuracy of the test results or
the tests themselves, if accessories other than those supplied by GN Otometrics A/S are used
for this device (i.e. eartips, electrodes, ear couplers, etc.).
