Aspect A-2000 XP BIS Monitor Features

The Aspect A-2000 XP is a bispectral index monitoring system, where it can monitor the state of the patient’s brain during procedures. The Aspect a-2000 XP BIS can be used in intensive care units and in the operating room. The system accrues data from the brain using EEG signals and a Digital Signal Converter (DSC) together with the Bispectral Index number to determine the level of sedation the patient is under. The DSC offers two channels of EEG in both the A-2000 and the A-2000 XP versions.

  • 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 deep anesthetic procedures
