Remote Screens
Instructions
This is an instructional screen that appears for a set amount of time.
To pause stimulation, press the button.
Press
to continue. The
button will appear as an option only when
stimulation is paused.
To begin increasing stimulation intensity press the button.
NOTE: When stimulation is on, the
symbol will be shown on the screen.
When stimulation is off,
OFF
will appear on the screen.
NOTE: Slowly increase intensity until the desired nerve response is obtained.
A nerve response should be confirmed with comfortable sensations of
tingling/pressure and in some cases tension in the muscle. Intensity is
adjusted in increments of 2 during lead placement testing.
To decrease stimulation intensity, press the
button.
To increase stimulation intensity, press the button.
NOTE: When targeting a mixed nerve in the periphery under ultrasound
guidance, it may be beneficial to assess several different locations and
stimulation intensities around the nerve until the optimal response is
achieved. In some cases, it may be beneficial to advance the stimulating
probe across the axis of the nerve to initiate stimulation at a low intensity
and to withdraw the introducer slowly across the nerve to assess optimal
location and response.
Once the desired level of stimulation has been reached, press the button
to turn stimulation OFF, then press the
button to continue.
NOTE: If desired response cannot be obtained, stop stimulation, set intensity
as low as possible and adjust position as needed before testing again.
12 Hz
IF TESTING AT 12 HZ: Stimulation at 12 Hz has two options to control
stimulation cycling:
1.
Fast Cycling (default): stimulation is delivered in periods with one
second of stimulation ON followed by one second of stimulation OFF.
This is labeled "1 Sec On/Off", or
2.
Slow Cycling: stimulation is delivered in periods with 20 seconds of
stimulation ON (5 seconds ramp up, 10 second plateau, 5 seconds
ramp down), followed by 10 seconds of stimulation OFF. This is
labeled "20 Sec On/Off".
