Handheld mode measurement
4.4 VEMP
The time signal appears on the screen. The indicator
light at the top left indicates whether the signal has
reached the rejection threshold (
◼
= no muscle contrac-
tion, not enough contractions,
= enough contractions to perform the measurement).
There are three levels of rejection to better adapt to the
level of contraction that the patient can provide.
However, with a rejection set on “low”, the measure-
ment is likely to be of a lower quality.
Click on the "
Start
" button to start the measurement.
4.4.1.1
Measurement
If both ears have been selected, the device will ask on
witch side it should start the measurement.
The
VEMP
measurement window opens, click on
"
Start
". A window appears, indicating the ear with
which the diagnostic begins. Click anywhere on the
screen to begin the measurement; the patient hears the
sound.
If several power levels have been chosen, the measure-
ments will be run from the highest power to the lowest.
Two curves are displayed. The bottom curve is the curve being constructed and its shape is updated in real-time
depending on the number of clicks already fed into the patient's ear. The top curve is a plot of the previous measurement.
This display mode indicates whether any reproducibility of the curves occurs as the measurement is made.
Use the
“stop”
button to stop the current measurement and pass to the next repetition, power or even the next ear.
The back cross in the right top corner allows to completely stop the measurement. Once data acquisition is over, the curve
is reconstructed. You then have the choice of saving the data by clicking on "
Save
" or deleting it by exiting the window
using the back cross.
When configuring the measurement, if both ears have been selected, at the end of the measurement on the first ear,
the device indicates that the measurement is about to begin on the other ear. Click on the screen to start the measurement.
