8.6 OAE Minimums
This setting allows the user to select if minimum amplitude values
will be used as part of the pass/refer criterion. If
Use Minimums
is
on
, a result is not considered a pass unless the OAE amplitude is
equal to or greater than the minimum value set in the protocol.
This is in addition to meeting the other pass criteria including the
minimum SNR and the number of passing frequencies for overall
test “Pass.”
The default minimum DP amplitude is -5 dB SPL.
The default minimum TE amplitude is -12 dB SPL.
Users of diagnostic instruments can set the minimum amplitude value when creating custom protocols.
Note: if
Use Minimums
is
on
then the minimum amplitude values are applied to all OAE protocols that
have a value established within the protocol. For more information regarding minimum amplitudes in
custom protocols, see section 9.
To change this setting, select
Use Minimums
from the
Set Up
menu. Using the up
and down
arrow buttons on the control panel select
on
or
off
and then press the right
arrow button to
select
and exit.
8.7 Save Mode (Patients)
In the default operation mode, the
ERO•SCAN
Pro saves the most
recent right and left ear test for each protocol. Once a new test for
that ear and protocol is started, the previous results are
overwritten. When the test results are printed they are flagged for
deletion and will be erased when a new test is completed.
The user can choose to enable the
Numbered Patients
feature.
When
Numbered Patients
are enabled the instrument will
automatically add a new menu,
Patient Names
, as the first screen
that appears when the instrument is powered on. This menu will
be automatically populated with two selections,
Patient 1
and
No Name
. To perform and save a test for
Patient 1
, select Patient 1 using the right
arrow button. The main menu with all available protocols
will appear. Select the desired protocol and conduct a measurement as described previously in this
manual.
Once a test has been completed for
Patient 1
, the instrument will automatically add
Patient 2
to the
Patient Names menu. The automatic numbering will continue until the test results are printed, at which
point all the numbered patients and test results will be flagged for deletion and then erased when a
new test is started. The new test will become the first test for Patient 1 and the automatic numbering
sequence will begin again. The instrument can hold up to 350 test results. The number of patients is
not limited.
NOTE: Users may also use the “Delete All” option found at the bottom of the Patient menu. Upon
confirming the selection, all tests and all patient placeholders will be deleted. An empty placeholder for
Patient 1 will appear in the Patient menu.
Use the
No Name
place holder for tests that are not associated with a specific patient.
