During a measurement, not only the Patch
connector, but also the DeltaScan Monitor
indicates` the progress of the measurement
(see Figure 27).
The measurement lasts until 120 seconds
of useable EEG data is collected. During the
measurement, the DeltaScan Monitor will
continuously and automatically judge all
acquired EEG data for its usefulness.
The better the electrodes are applied and the
better the patient complies to the instructions,
the higher the quality of the EEG data, and the
faster the measurement will be finished.
Step 4
After a successful measurement, the Monitor
automatically switches to the analysis phase,
calculating the DeltaScan score (see Figure 28).
Please note! The device checks every minute
whether there is enough progress in gathering
good data.
If at one of these moments (max.
4 minutes), it was not possible to acquire
enough useable EEG data from the patient,
the measurement will stop. The user can
immediately start a new measurement on the
patient, but it is advised to assess the position
and condition of the patient first, to redo the
skin preparation, and to apply a new Patch.
It might be practical to find a more relaxed
position for the patient such that compliance to
the three instructions is easier for the patient.
Please note!
The user can stop a measurement
anytime during a recording, by pressing the left
key on the DeltaScan Monitor. In this case, it is
not possible to continue the measurement.
