The INVOS® Cerebral/Somatic Oximeter has doubled its data channels from two to four, now enabling clinicians to use it for cerebral oximetry, skeletal muscle tissue (somatic) oximetry or both simultaneously. This latest evolution makes the INVOS System the first and only commercially available noninvasive oximeter to simultaneously monitor changes in regional oxygen saturation (rSO2) of blood in both the brain and other regions of the body. Like its predecessor, the INVOS Cerebral/Somatic Oximeter can be used on adult, pediatric and neonatal patients in clinical settings where the brain and body are at risk of reduced-flow or no-flow ischemic states.

Next-Generation INVOS System Enhancements

· Ability to place up to four sensors (instead of two) for additional blood
· oxygenation change data from the brain and body
· Larger screen display for easier viewing
· Video output to a second, remote monitor
· Improved data downloading via USB memory device
· Enhanced user preference settings
· Improved signal quality indicator
· Reduction in weight and size

The Power of Cerebral - Somatic Monitoring

Simultaneous rSO2 monitoring of cerebral and somatic tissue is most rapidly being adopted by pediatric and neonatal operating rooms and intensive care units where clinicians use this data to:

· Track the stability of cerebral and peripheral
· (somatic) blood oxygen saturation in a
· noninvasive, immediate way
· Use associations and changes between
· cerebral/somatic rSO2 values to, for example, monitor
· whether the peripheral circulation is shutting down to
· preserve the brain (an early indicator of shock)
· Determine whether vascular beds surrounding various organs are
· adequately oxygenated
· More closely identify and manage regional oxygenation issues linked to positive
· and negative clinical outcomes
· Obtain additional objective data for clinical decision making

Overall Benefits of Regional Oxygen Monitoring

The INVOS System's regional oxygen saturation (rSO2) is a vital sign that can help critical care teams detect and correct blood oxygenation changes that can lead to complications and poor outcomes.

Because some traditional vital signs and measures in the operating room and intensive care unit reflect systemic (whole body) status or are time-delayed by labs, they can sometimes fall short in quickly detecting regional changes in oxygenation. The addition of rSO2 monitoring can help fill this void:

  • By monitoring changes in regional blood oxygen saturation in the brain or body area directly under the sensor, often resulting in an earlier warning of ischemic problems
  • By giving critical care teams more data and control over oxygenation imbalances linked to positive and negative outcomes
  • By immediately reflecting the effectiveness of interventions taken to correct ischemic problems

Reflecting the Color of Life™

The In Vivo Optical Spectroscopy (INVOS) System "reflects the color of life" by identifying hemoglobin and red-colored oxygenated hemoglobin molecules within red blood cells, and measuring the relative amounts of each to determine whether there is adequate oxygenation. The resulting regional oxygen saturation (rSO2) is a vital sign that helps critical care teams detect and correct blood oxygenation issues that can lead to complications and poor outcomes. Since brain cells and organ tissues die within minutes without proper oxygenation, measurement of this color provides potentially life-saving or life-changing information. When the rSO2 value shows a change in blood oxygenation toward or beyond threshold levels, the care team can intervene to potentially lessen or prevent complications.
