• 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 (Viola only)
• select the type of threshold to examine (HL/UCL*);
• select the stimulus input signal (21):
• select the masking input signal (22):
