The Cerebral State Monitor (CSM) is a non-invasive measurement tool for use by trained healthcare
professionals to measure the level of consciousness (LOC) in all areas of the hospital. Based on
EEG, an index (CSI) is calculated, which is used in the estimation of LOC. The CSM displays the CSI
but does not perform any data interpretation (i.e., all data interpretation is performed by a
physician).

Indications for Use:

The monitor is intended for use in monitoring the hypnotic state of the brain by data acquisition of
EEG signals of the anesthetized or sedated patient in all areas of the hospital.
