INVOS™ System technology gives you a noninvasive "window" to the body's microvasculature: a direct and dynamic site of gas exchange that transports about half of the body's blood volume. Measuring blood oxygenation in the microvasculature results in sensitive and site-specific insights on perfusion adequacy or - with multi-sensor monitoring - perfusion distribution across the brain and body. After reading this guide, clinicians should be able to:

  • Describe the link between regional cerebral oxygen balance and the INVOS™ parameter, regional oxygen saturation(rSO2)
  • Integrate brain rSO2 information with other physiologic and clinical data before, during, and after surgery
  • Identify special situations which can influence cerebral rSO2 monitoring
  • Discuss the clinical management and responding to cerebral rSO2 monitoring
