•
start the test (START/STOP button). The test will start only if the status
of the probe is indicated as READY;
•
a first tympanogram is generated and the pressure in the ear canal is
raised automatically to +400 daPa;
•
invite the patient to swallow several times, as indicated in the pop-up
message, and press the CONTINUOUS* function button;
•
a second tympanogram is generated and the pressure in the ear canal is
lowered automatically to –400 daPa;
•
invite the patient to swallow several times, as indicated in the pop-up
message, and press the CONTINUOUS* function button;
•
a third tympanogram is generated and all three graphs are shown in the
display.
Eustachian Tube Function test (ETF) with perforated
eardrum
•
Select the ear being examined, left side or right side.
•
Select the maximum pressure (PRESS. MAX* function buttons), or,
the pressure that will be established in the middle ear of the patient for
the purposes of assessing Eustachian tube function;
•
select the duration of the test by pressing the DURATION* function
button (selectable values are 20, 30, 40 or 50 seconds)
•
start the test (START/STOP button). The test will start only if the status
of the probe is indicated as READY.
•
ask the patient to swallow so that a variation of pressure can be induced
in the examined ear, and functionality of the Eustachian tube thus
evaluated.
Quick A / Quick B
Quick A and Quick B are sequential tests in which the tympanometry
examination and then the acoustic reflex examination (configurable on the
Settings page of the instrument) are run automatically one after the other.
•
access the window relative to the tympanometry examination;
•
select the ear being examined, left side or right side;
•
select the rate at which the pressure sweep occurs during the course of
the test (P. RATE *);
•
start the test (START/STOP button). The test will start only if the status
of the probe is indicated as READY.
•
once the test has been concluded, press the scroll button (<<* or >>*)
to change the type of test displayed.
Pure-tone audiometry
•
select the type of threshold to examine (HL/UCL*);
•
select the stimulus input signal (21):
•
