Notes:
for a correct use of PPI and Tetanus modes, the user must validate at least the following
three steps:
Connection and positioning of stimulation electrodes
Connecting the AlgiScan stimulation cable to the electrodes
Patient electrode conduction control
As soon as the AlgiScan is positioned in “Tetanus” or “PPI” mode, it is possible to ac
-
tivate the measurement by pressing the main button, if the conduction of the electrodes is
adequate (green electrode icon).
To start the measurement, press and hold down on the main button. The user hold
his finger pushed on the button during all the time.
If the user removes his finger of the button during the test, AlgiScan stops immedi
-
ately the test and the stimulation (PPI or Tetanus tests). The result is not valid, and therefore
not displayed, if the recording stops less than 2 seconds after the end of the electrical stimu

lation.
Note that the AlgiScan emits a first beep when the electrical stimulation starts. Dur
-
ing the stimulation, the device emits a beep at each new level, the tone of which increases with
the intensity. A final beep indicates the end of the stimulation.
During this time interval, it is essential that the AlgiScan is not moved and that the patient does
not close his eye. If this does happen, a new measurement must be performed.
During the test the AlgiScan display shows a countdown of the time remaining.
Connection and positioning of the stimulation electrodes
The electrodes can be positioned on different sites on the patient’s body. The
practitioner must choose a relevant site for the desired measurement while ensuring there are
no injury risk for the patient. In many situations, the anterior forearm as well as the C5 and T2
dermatomes can be valid sites.
It is important to remember that in order to obtain a correct stimulation, a good
connection between the electrodes and the patient’s skin as well as correctly stuck electrodes
are essential.
