C. Reflex Screening results
The detected reflex is shown in the results area.
• Stimulus type level
• Progress indicator during measurements
• Deflection curves are shown when a reflex has been detected.
If a reflex is not detected, the highest stimulus is displayed together with a
No Response
indication.
If the system cannot automatically analyze a reflex measurement, a Not Tested indication is shown.
D. Tympanometry results
The results table shows the results related to the currently selected curve:
• Probe (the probe tone in Hz)
•
TPP
(Tympanometric Peak Pressure)
• ECV (Equivalent Ear Canal Volume)
•
SA
(Static Peak Admittance), or
SC
(Static Peak Compliance) when volume equivalent units are used
• TW/Ratio (Tympanometric Width/Tympanometric Ratio). Describes the steepness of the curve.
•
Type
(Jerger types A, As, Ad, B, C, D and E denote the shape of the 226 Hz curve). You can set the type to be
determined automatically, and you can subsequently change it manually, if necessary.
E. On-screen selections
Curve selection Press the Previous Curve or Next Curve softbutton to select the desired curve in
the Reflex Screening and Tympanometry result tables.
Manually adjusting the TPP Press the Edit TPP softbutton, use the dial to move the marker to the desired
TPP, and press the Done softbutton.
Changing tympanogram curve type Press the Edit TPP softbutton. Press the Change Type softbutton until the
desired type is shown, and press the Done softbutton.
Deleting a curve Select the curve you wish to delete, and press the Delete button.
To replace a single measurement, delete a curve and adjust the measurement
selections to redo the single measurement.
9.2 Sequence testing
A test sequence is a predefined set of automatic tests which can be performed automatically.
You can perform the immittance tests in a sequence:
• Diagnostic sequence
Tympan Reflex Threshold (auto search) (+ Reflex Decay, if selected from the menu).
• Screening sequence
Tympan Reflex Screening.
