BIS™ monitoring technology provides information about patient status to help clinicians address each patients anaesthetic requirements. This may be valuable for:
BIS™ monitoring provides an objective measure of the patient’s depth of consciousness, and enables you to monitor anaesthesia for each patient.

How does our sensor technology work to capture the low-voltage EEG signal?
First, we use a conductive ink that is printed directly on the surface of the sensor, under the adhesive foam and Zipprep™ technology. This creates an electrode surface that is helpful in picking up the low-voltage EEG.
Second, the Zipprep technology helps clear away the first layer of the epidermis. The mechanical action of pressing on the electrode results in the tines clearing away some of the first layer of dead skin cells, exposing the inner, more electrically conductive layer of skin. The conductive gel within the electrode permeates into this newly exposed area, creating a good electrical pathway between the EEG-carrying inner layers of skin and the conductive traces within the sensor. The EEG signal is then carried through these traces to the BIS™ monitor.
Third, we include a thin layer of sponge that contains a very precise amount of gel. This gel creates a "bridge" between the forehead and the conductive electrode surface.
These combined components help achieve an enhanced environment to acquire and maintain the EEG signal.
