User Manual ToFscan 15
The symbol in front of a result indicates a possible presence of a impaired
measurement. The user can do the test again (while respecting the waiting time) or wait for the next
test scheduled in the case of “AUTO TOF” mode.
Note:
The recommended waiting time between each stimulation are shown at the end of each
description of the various stimulations (or tests).
Only ‘TOF’ tests are commonly used for the NMT monitoring for the eyebrow muscle (stimulation of
the facial nerve).
When disconnecting the ToFscan from a patient at the end of the operation and before
connecting a new patient for new operation, the display of the ToFscan must be reset. For this, press
the wheel an release the wheel button.
TOF mode
The “TOF” mode includes various options or sub-menus. Each of these options is detailed
below. With this mode, the TOF stimulation can be done two ways, either directly or manually by the
operator, or automatically at a repeated interval selected by the user.
“TOF” sub-menu
After selecting the “TOF” menu and then the “TOF” sub-menu, the user can start a “TOF”
stimulation (or test) by pressing and holding the selection wheel. Prior to this, he must verify that
the output (current in mA) of the selected stimulation is appropriate for the level of anaesthesia, the
level of neuromuscular blockade and the patient’s profile. For further information on stimulation
output, refer to the “Parameters” section.
TOF stimulation is one of the most commonly used forms of stimulation, comprising 4
stimulations (of 200 µs) at 0.5 second intervals.
If the ToFscan is connected to a cable fitted with an accelerometer sensor, after the
electrical stimulation it will display a calculation of the percentage of the range of the 4th response
against the first (ratio T4/T1 TOF as a %) in yellow in the middle of the screen. The ToFscan also
displays a bar graph allowing the visualization of the range of the different responses.
If a “Reference” test (or stimulation) was performed, it will be symbolized on the top of the bar graph
by a horizontal yellow line. ToFscan automatically displays the T4/Tref ratio.
