2.1 INTRODUCING THE A-2000 BIS MONITORING SYSTEM
Aspect Medical Systems A-2000 BIS Monitoring System is intended to monitor the state of the brain by data acquisition of EEG signals in the intensive care unit, operating room, and for clinical research. The BIS, a processed EEG variable, may be used as an aid in monitoring the effects of certain anesthetic agents.
The A-2000 processes raw EEG signals to produce a single number, called the Bispectral Index™, or BIS, which correlates to the patient’s level of hypnosis. It operates from an AC power source of 100V to 240V, 50/60Hz, and provides a minimum 20 minutes of automatic back-up battery power.
The monitor is menu-driven with fixed keys for choosing the options available.
2.1.1 Principal Components
The system is composed of a monitor and a digital signal converter, with a patient interface cable (PIC), and BIS Sensor.
The monitor contains the operator control panel, an electro-luminescent display screen, and
connectors for the digital signal converter and printer.
