Probe Check; Testing Children With Pe Tubes; In-Ear Stimulus Calibration After Probe Check - Interacoustics OtoRead Instructions For Use Manual

3.12.3

Probe check

After the test ear is selected, the probe check will be begin automatically. This probe check screen displays
the selected ear side in the corresponding color (red for right ear, blue for left ear) and a gauge representing
the probe check status .
3.12.4

Testing children with PE tubes

To test children with PE (pressure equalizing/ventilation) tubes, the probe check needs to be disabled. This
is accomplished by first inserting the probe with an appropriate ear tip into the ear canal and obtaining a
proper seal. To disable the Probe Check at the main menu select the ear to be tested by holding down the
LEFT or RIGHT keys for 3 seconds until the green 'TEST' light turns off. Once the key is released, the
OtoRead will perform the in-ear calibration and test as usual.

In-ear stimulus calibration after probe check

Immediately after the probe check, the OtoRead
prior to the start of each test. During calibration a series of tones will be presented to the ear canal to
calibrate the stimulus levels of the frequencies to be tested.
Following calibration of the test tones, the test phase will begin automatically.

Leaking: The needle points to the orange, right side of the gauge.
The detected ear canal is too large for the test to begin as the probe
is not in the ear or there is a large leak.
The indicator will remain orange until a seal is obtained. Appropriate
adjustment of the probe/ear tip position and ear tip size selection
should be made until the indicator falls within the green area and
remains stable.
Sealing: The needle points to the top, yellow part of the gauge.
The ear canal volume is in the target range for testing. A seal has
been detected and now the instrument is looking for a consistent
seal. Once this is confirmed, it changes to 'in ear' and can begin a
test.
In Ear: The needle points to the green, left side of the gauge.
The test will begin automatically if the probe fit is stable. When the 'in
ear' status is confirmed, the unit will automatically begin testing
(AutoStart) and the yellow 'TEST' LED will be illuminated throughout
the test.
If the test does not progress past the probe check phase, change the
probe tube and check that the Micro-probe connector is fully seated
device socket and try again.
