Measurement on ECHOSOFT
6.3 Hydrops (Shift-OAE and DPMC)
6.3.2
Description of the measurement window
1.
Graphic display area :
•
1a: The phase curve represents the measured phase shift value included between ±180°. The color of each
point on the scope depends on the position of the patient. The index given above is the phase shift value in
degrees.
The mouse wheel is used to zoom on the phase curve.
•
1b: The green curve represents the effective signal. The index, indicated in blue is the ratio between the
effective signal and the average noise in dB (S/N). To validate a point, this value must be greater than 6dB.
•
1c: The red curve represents the average noise level.
•
1d: For each position a phase average is calculated and placed on the graph, this average may be adjusted
directly with the mouse.
2.
Settings used for the measurement
3.
The delta between the different averages.
A color code is used to qualify the phase shift degree:
Black
Orange
Red
Normal phase shift
Borderline phase shift
Pathological phase shift
Shift-OAE
<38°
>=38° et <=40°
>40°
DPMC
<18°
>=18° et <=20°
>20°
If the
Left
,
Right
and
Minus
values are greater than 7kΩ, check that the clamps and electrophysiology ca-
ble are properly connected, check that the "
Patient Reference
" electrode is properly attached.
In case these values are less than 10kΩ but are balanced (deviation <±2kΩ), the measurement is possible,
but the results may be degraded.
