OTOWAVE 302+ INSTRUCTION FOR USE
1.
INTRODUCTION
1.1.
THANK YOU
Thank you for purchasing an Amplivox Otowave 302+, a desktop-controlled impedance meter that will give many years
of reliable service if treated with care.
1.2.
INTENDED APPLICATIONS
This instrument is designed for use by trained personnel only, such as audiologists, ENT surgeons, doctors, general
practitioners, hearing aid dispensers, child health professionals and hearing healthcare professionals with a similar level
of education
.
It is not recommended to use the equipment without the necessary knowledge and training.
The Otowave 302+ is to be used to obtain information on medical and functional conditions of the middle and outer ear
as well as to assess hearing functions throughout acoustic reflex testing. The Otowave 302+ can be used on all ages and
performs two types of measurement:
•
Tympanometry:
To measure the compliance of the tympanic membrane and middle ear at 226 Hz or 1000 Hz
over a range of pressures.
•
Acoustic Reflex Testing:
The Otowave 302+ measures both ipsilateral and contralateral acoustical reflexes. The
tests are performed either at ambient or peak pressure, based on the outcome of the tympanometry.
1.3.
CONTRAINDICATIONS
Always visually inspect the outer ear and the external auditory canal for abnormalities before testing. Testing should
not be performed on patients if the following items are applicable.
•
Acute external auditory canal trauma
•
Discomfort (e.g. severe otitis externa)
•
Occlusion of the external auditory canal
•
Discharging ear
•
Recent stapedectomy or middle ear surgery
•
Presence of tinnitus, hyperacusis or other sensitivity to loud sounds may contraindicate testing when high
intensity stimuli are used
