OPERATING PRINCIPLE, AND DELIRIUM PROBABILITY SCORE
The dedicated, self-adhesive DeltaScan Patch includes 3 electrodes,
to easily collect relevant EEG signals of the patient:
•
The 1st electrode on or close to
Pz (on the crown of the head)
•
a second electrode on or close to
Fp2 (above the patient’s right eyebrow)
•
a third (Reference) electrode on or
close to Fpz (above the nose on the
forehead)
Pz, Fp2 and Fpz refer to defined EEG
electrode locations in the standard
10/20 EEG setup (see Figure 4).
The acquired EEG signals are amplified, digitized, and processed by the software algorithms
of the DeltaScan Monitor, to present a Delirium Probability or DeltaScan Score to the user.
The DeltaScan Monitor provides signal analysis technology intended for use as an adjunct
to clinical judgment. The DeltaScan Score should always be interpreted in conjunction with
other available clinical signs for clinical judgment.
Do not rely solely on the DeltaScan Score alone for starting or adapting delirium treatment
(which may include administration of medication). Clinical assessment should be leading in
deciding on patient treatment.
