– Otowave 102-C Operating Manual
The display shows:
•
The peak compliance, in ml (Pk)
•
The pressure which gave the peak compliance in daPa
•
The Gradient, in daPa (Gr)
•
The Ear Canal Volume (ECV) in ml measured at 200 daPa.
•
A pass/refer sign indicating if tympanogram appears to be normal or not
•
A plot of compliance against pressure.
•
Normative box (based on BSA recommendations)
•
Pass (
) / Refer (x) sign when tymp peak falls into normative box or not (refer)
•
Pressure cursor to be operated with up
▲
and down
▼
navigation keys.
Review the tympanogram to ensure that the peak compliance point selected by the Otowave is suitable. If
required it is possible to select an alternativ
e peak using the ▲ and ▼ keys. The figures displayed will change
to reflect the peak selected, and will be saved with the tympanogram.
To repeat the test, press ◄.
When satisfied with the tympanogram press ►.
If reflex test(s) were carried out these results will now be displayed:
The display shows:
•
The frequency and level of the reflex stimulus
•
“PASS” if a reflex was found, else “x” (No Response)
•
A plot of compliance against time
If the reflex test was performed at more than one frequency use the
▲ and ▼ keys to view the results for the
other frequencies.
If the Otowave 102-C was set to
test for a reflex at all levels of the stimulus press ► to view an additional
display following the reflex graphs. This shows a summary of the levels and frequencies at which a reflex was
detected. The dash symbol “-” is shown if a reflex tone was not presented at the level indicated.
