Aspect A-2000

Aspect A-2000 Bis Monitor Features

The Aspect A-2000 BIS is a bispectral index anesthesia monitor. The BIS system monitors the sedation level of the patient based on the acquisition and the processing of EEG Signals. The EEG is read by the bispectral index monitor, processed, and produces a number that is called the bispectral index - this is connected to the patient's level of sedation. The Aspect A-2000 BIS is used to monitor the cerebral electrical activity of a patient.

• Reduce the sedation drug use
• 35%-55% fast wake-ups and extubations
• Improve the quality of post anesthesia recovery
• Reduce recovery time
• Can enhance the performance during cardiac or other other deep anesthetic procedures
