stimulus may be set between 85dBHL and 100dBHL; the
maximum level of contralateral stimulus may be set between
85dBHL and 110dBHL.
Levels:
Use the
▲
and
▼
keys to choose the maximum level of reflex
stimulus to apply and the step size between the levels of the
preceding stimuli. The maximum level of stimulus may be set
between 85dBHL & 100dBHL. Press the
►
key to confirm the
selection or the
◄
key to cancel.
95 dB
5 dB steps
Frequencies:
Use the
▼
key to scroll through the frequencies available for
each of the ipsilateral and contralateral stimuli (500Hz,
1000Hz, 2000Hz & 4000Hz), and then the
▲
key to select (
)
or deselect (-) the frequencies at which the reflex stimulus is to
be applied. Then press
►
to save the entire selection.
1kHz ipsi
Selection:
Use the
▲
and
▼
keys to choose the circumstances when a reflex
measurement is to be made (always, never, only if a compliance
peak is found, or only after confirmation is made at the start of the
test sequence). In cases where a compliance peak has not been
established a pressure of 0daPa is used. Press the
►
key to confirm
the selection or the
◄
key to cancel.
Only if peak found
Threshold:
Use the keys to choose the change in compliance required to signify
that a reflex response has been detected (0.01ml to 0.5ml). The
default is 0.03ml.
0.03 ml
Auto-Stop:
By default the reflex test at each frequency will stop at the lowest
level of stimulus that produces a response. By setting REFLEX
AUTO-STOP to NO the Otowave 102 will test for a reflex at all
selected levels. (Note that 100dBHL at 4000Hz is not available).
No
Polarity:
Define the polarity of the reflex graphs, if the reflex is plotted
upwards (
UP
) or downwards (
DOWN
).
Up
Filter:
Use the keys to choose either 2Hz or 1.5Hz. The default of 2Hz is
suitable for most circumstances. However if a smoother reflex plot is
required for better interpretation 1.5Hz may be chosen.
2 Hz
Defaults:
Reset the sweep settings of the selected profile(s) to its original
settings.
