1Introduction
This manual provides instructions for the use of the Otoport OAE+ABR
(Otoport Advance and Screener models). Instructions that apply only to the
Otoport Advance are indicated with the following symbol:
The Otoport provides high quality OAE and ABR measurement features in
a compact, hand-held format.
The Otoport is simple to use and with powerful measurement features
performs an automatic analysis of cochlear status within seconds.
Customisable Stop criteria control the test’s automatic stop.
1.1 Intended Use
This Otodynamics Otoport/Otocheck OAE+ABR device is indicated for use
when there is a requirement to screen for hearing disorders by objective
and non-invasive means. ABR, TEOAE and DPOAE screening test
results are automatically interpreted and a clear ‘Pass’ or ‘Refer’ result is
presented to the user who will be a trained screener, audiologist or medical
professional. Use of the device is indicated when the patient is unable
to give reliable voluntary responses to sound, especially with infants.
Use of the device facilitates the early detection of hearing loss and its
characterization.
The TEOAE and DPOAE analytical functions of the device are
indicated when objective non-invasive clinical investigations require the
characterization and monitoring of the functional status of the peripheral
auditory function. For this purpose the device is intended to be used by
audiologists or other audiologically skilled professionals. These TEOAE
and DPOAE tests are applicable to populations of any age to obtain
objective evidence of peripheral auditory function.

1.2 General Guidance
Each test type provides evidence of normal peripheral hearing function
objectively and non-invasively.
The screening functions of this instrument are especially suitable for
use with infants. The ABR screening function uses conventional Fsp
methodology to detect the response supported by waveform identication
(Template Correlation) which is optimised for infants from 34 weeks to
6 months gestational age. Template-free pass criteria for ABR may be
selected for use with patients outside this age range (see chapter 17 Test
Setup, section 17.7.3, ABR stop criteria). OAE screening functions include
Otodynamics classic Quickscreen TEOAE technology and Rapid DPOAE
technology (depending on the model).
The device can be used in a wide range of di󰀨erent environments for
example in the well-baby nursery, the NICU, a doctor’s o󰀩ce, an audiology
clinic, the outpatient clinic or in the home. For optimum results and short
test times the room should be quiet and the patient should be very quiet
and still during the test. The device will clearly indicate levels of acoustic
noise and electrical interference (with ABR). Use this as a guide to improve
the testing environment.
The screening functions of the device are intuitive and suitable for
operation by trained screeners without specialized knowledge. Testing and
interpretation is automated. The TEOAE and DPOAE analysis functions
of the device are intended for clinical audiological investigations when
objective non-invasive characterisation and monitoring of the functional
status of the peripheral auditory function is required. These functions
are intended for use as a part of the audiological diagnostic test battery,
not as solitary diagnostic tests. The OAE analysis functions provided on
some models are of particular interest to Audiologists, Ear, Nose and
Throat specialists, Neurology specialists, researchers and other health
professionals concerned with the di󰀨erential diagnosis of hearing problems,
the monitoring of changes to hearing, the conservation of hearing or the
detailed measuring of peripheral auditory function.
