Introduction of Cortical Activity Index
(CAI) System
Users must carefully and thoroughly read the safety management information described in this
instruction manual and be aware before setting and using CAI device.
CAI Overview
CAI is a system providing patient’s consciousness level through their brainwave analysis during
surgical procedure to medical staffs, and the system comprises with CAIs (brainwave sensor),
CAIx (amplification module), CAI monitor and algorithms for calculation and analysis.
CAI, which has capability of setting various conditions, is designed to monitor hypnotic state of
brain by collecting and analyzing brainwaves.
CAI provides digitalized information through operational processing of unprocessed EEG signals.
This processed information, which is called arousal index (AI) or CAI index, is closely correlated
with arousal degree of a patient.
Users can change data indications and review stored data via menus on the touch screen
display.
CAI provides following information.

CAI provides following information.
•
Present CAI index
•
Trend graph of CAI index
•
Real time unprocessed EEG waveform graph
•
Various signal performance indexes (EMG, SQI)
•
Burst Suppression Ratio (BSR)
•
Warning index and message
CAI can determine whether the impedance of patients is within normal range, using assembly
compatible software algorithm technology as well as highly advanced components with cable
to connect CAIs and CAIx for patient interface.
In addition, CAI has convenient functions for user settings, which enable users to easily display
information and review stored data.
