Handheld mode measurement
4.2 ABR
The
ABR
measurement window opens, click on
"
Start
". The measure will begin, ensure that the patient
is not too agitated during the measurement.
Two stacked curves are displayed, they are built turn by turn. This measurement method enables to calculate the
correlation between the two curves.
The rejection indicator warns you when the rejection threshold is reached. If it stays locked on red it means that the
patient muscular activity is too high. When the patient will be more relaxed, the measurement will automatically resume.
If this problem remains, the electrode eventually needs to be replaced to reduce the impedance, otherwise, the test should
be reported when the patient will be less agitated.
The “
Stop
” button and the top right cross enable to stop the measurement.
In a normal use, the measure will automatically stop:
If the maximum measurement time has been reached
and wave V is not detected, then the device cannot val-
idate the measurement.
If the correlation between the two curves is good and
the two markers for the wave V are placed at the same
place, then the test validated.
In both case it is possible to directly save the measurement or to consult it before choosing to save it or not.
