O3 monitor

  • > May help clinicians monitor cerebral oxygenation in situations in which pulse oximetry alone may not be fully indicative of the oxygen in the brain.
  • > Provides continuous display of:
    • Difference between the currently displayed rSO2 and a user-defined baseline
    • Difference between rSO2 and SpO2 (from the pulse oximetry sensor connected to the
    • Area under the curve (AUC) which quantifies the duration and depth of patient’s stay below the user-defined rSO2 low alarm limit
  • > In a study published in Anesthesia and Analgesia researchers found O3 regional oximetry provided absolute root-mean-squared error of 4% and relative root-mean-squared error of 2.1%.1
