4.9.2.
PERFORMING TYMPANOMETRY
Depending on the protocol selected, the test sequence will perform both tympanometry and acoustic reflex
testing in one run without removing the probe.
Please note:
The protocol selected by default runs a tympanogram together with ipsilateral reflexes.
An instruction on the screen will guide you through the test
sequence. The test will start automatically by inserting the
probe into the patient
’s ear.
Insert the probe into the test ear. While the probe placement
is evaluated, indicator LED b and c on the device will light up
alternating as well as the indicator light on the probe will
change it’s color from yellow to green by turns to indicate the
test start.
Once an adequate seal is detected the tympanogram
measurement is made. This takes about 3 seconds. It is
important not to move the probe and to ask the patient to
remain very still during the test.
TROUBLESHOOTING:
In some cases no pressure can be build up and the test
sequence will stay in the
EQUALIZE PRESSURE SCREEN
.
This situation can occur for the several reasons. Solution to
this issue can be found in the
TROUBLESHOOTING
SECTION
