CSI Scale
The CSI is a unit-less scale from 0 to 100, where 0 indicates a flat EEG and 100 indicates EEG activity corresponding to
the awake state. The range of adequate anaesthesia is designed to be between 40 and 60. All values in the table are
approximate values based on the mean values of the patient behaviour.
EMG
Facial EMG may increase the CSI under certain conditions. The monitor incorporates an EMG filter that removes most of
the potential interfering EMG activity. The EMG% bar shows the energy of the EMG level in the 75-85 Hz frequency band
(0-100 logarithmic). The bar is located on the right side of the display.
EMG activity is expected to be present when the patient is awake. When the patient is asleep, EMG activity can increase
due to:
Reflex reactions to painful stimuli during surgery.
Lack of muscular relaxation.
Muscular rigidity caused by some opioids (analgesics).
Presence of large external electrical fields, e.g. diathermy.
The EMG bar should be checked frequently, especially in case of a sudden increase in the CSI. If the increase in CSI is
accompanied by an increase in muscular activity, there is a risk that EMG is causing interference. When this happens,
attention must be paid to the stimuli receive by the patient during surgery. In the presence of hypnotically unrelated EMG,
administration of a neuromuscular blocking agent will cause the CSI to decrease. Since patients receiving neuromuscular
blocking agents cannot exhibit movement as a sign of arousal, the CSI is a valuable tool in their anaesthetic management.
