INTRODUCING THE BIS VISTA MONITORING SYSTEM
Introduction
The BIS VISTA Monitoring System is a user-configurable patient monitoring system
designed to monitor the hypnotic state of the brain based on acquisition and processing of
EEG signals. The BIS VISTA system processes raw EEG signals to produce a single
number, called the Bispectral Index™, or BIS, which correlates with the patient's level of
hypnosis.
The BIS VISTA monitor display consists of:
• The current BIS number
• Trend graphs of processed EEG parameters
• Raw EEG waveforms in real time
• Various signal quality indicators (EMG, SQI)
• Suppression Ratio (if requested by the user)
• Burst Count number (when a BIS Extend Sensor is in use)
• Alarm Indicator and Messages
The system performs self-tests to ensure that the monitor and its components are
functioning properly and that impedance levels of patient sensors are within acceptable
limits. Touch screen menus allow the user to change the data display and review stored data.
