4.4. Getting Started
The offered sequence of operations will allow you to speed up the use of
Neuro-Audio-Screen
screening system for OAE recording. The operating order of
ABR test performing is described in section 5.8 “Patient Preparation for ABR Test”
and section 5.9 “ABR Test”. The first four steps are fulfilled in any case regardless of
the used technique.
First of all perform the otoscopic study prior to testing. Read carefully this technical
manual before you start to examine the patients.
Step 1.
Connect the power supply unit to charge the battery. The battery is charged
for 3-4 hours (see section 5.3 “Rechargeable Battery Charge”).
Step 2.
Connect the OAE probe to the screening system. Place the ear tip as far
down as possible on the OAE probe tip.
Step 3.
Switch on
Neuro-Audio-Screen
by pressing
on/off button for 2 seconds.
Step 4.
After screening system loading, set the printer type and address if you have
wireless thermal printer. Enter the OAE probe sensitivity, date and time. Set the report
type. The detailed procedure is described in section 6.5 “System Settings”.
Step 5.
Insert the ear tip deeply into the patient’s ear canal to obtain a seal. The order
of OAE probe insertion into the ear canal is described in section 5.5 “Patient Prepara-
tion for OAE Test”. Choose the technique and the tested ear with the use of “up/down”
buttons and “Select” key.
Step 6.
First,
Neuro-Audio-Screen
checks the quality of OAE probe setting, performs
calibration automatically and then fulfills OAE recording. At high noise level the noise
level indicator highlights red. This is normal and it takes place quite often. Anyway the
study can be performed if the indicator does not glow red constantly, however it
impacts the final result of the recording. Once the test is finished, the test result is
displayed on the screen (PASS/REFER).
Step 7.
After the test finishing, you can save the results in the screening system
memory by pressing “Close” button and answering “Yes” to the question “Save
exam?”. If you have printer, you can print the results. Switch on the printer by pressing
the round button on top. Press “Print” button on the screening system. The results of
the current exam will be printed.
