positive pressure to a negative ending pressure. The right arrow
indicates that the pressure will sweep from a negative starting pressure to
a positive ending pressure. The choice of which start button to select
depends on the starting pressure for the test. The starting pressure is set
in the Settings dialog from the Settings button on the menu. The default
start pressure is +200 daPa. An error message is displayed if the Start
button direction conflicts with the starting pressure.
7.
When the test begins, the systems checks for any leaks or occlusions and
adjusts the pressure to the starting pressure as set in the protocol. This is
indicated by the green lamp on the probe box (and indicator on the
device screen) changing from blinking to steady.
8.
View ongoing test results on the graphic display area, and on the
pressure and admittance meters. The pressure sweep continues to the end
of the pressure range and automatically stops or enters into a hold status if
more than 1 tympanogram has been defined in the settings. The HOLD
button may be pressed prior to completion of the sweep. The user may
abandon automatic testing by pressing the STOP button at any point for
difficult to test patients.
9.
Upon completion of a pressure sweep, numeric values for compliance
peak (mmho), pressure peak (daPa), and gradient (if selected) for the
tympanogram appear in the table.
10.
From the Hold condition an additional tympanogram may be collected by
pressing the Start button in the opposite sweep direction. Up to three
tympanograms may be collected.
11.
Pressing the STOP button ends the tymp test. Additional tymp data
cannot be stored to the tab. Upon completion of a pressure sweep the
compliance scale changes appropriately for the peak measurement. The
zoom function may be used to examine the data more closely and
call out and mark peak points.
Acoustic Reflex

mode by pressing REFLEX
button on the
front panel. The display will show the format for the reflex threshold
and growth tests.
2.
