General
The qCON provides reliable information on the level of consciousness of the patient, helping
the anesthesiologist to administer anesthetic drugs by inhalation or intravenously safely.
The qCON index has been designed to be used in the monitoring of the level of
consciousness of a person during the application of general anesthesia or in intensive care.
The qCON index is obtained from signals of electroencephalogram (EEG) recorded with three
surface electrodes placed on the patient's forehead and analyzed by a digital process. The
result is the index "qCON ", "Index of Consciousness", which serves as a guide to the experts
to determine the patient's level of consciousness during anesthesia.

Preparations
For a correct measure of the EEG signal, it is advisable to prepare the skin for reducing the
high impedance that exists in normal conditions. To this is recommended to use very fine
sandpaper designed specifically to clean the surface layer of the skin of the patient.
Before placing the electrodes clean the patient's skin using carefully the sand paper on the
given area.
Location of electrode
As described above, one end of the patient cable has three snaps (red, yellow and green) that
are connected to the electrodes when the patient’s skin is cleaned, as shown in Figure 28-1.
Figure 29-1. Location of electrode
The connectors correspond to the end of the red wire (+), yellow (reference) and green (-).
The proper placement is ensured by the three different colors of the snaps.
