A Reliable First Alert1 for Confidence in Your Response

The more you know about your patients, the better care you can provide. Cerebral oximetry can play an important role in that care as a valuable “first alert.” Because it monitors for haemodynamic changes and deteriorating patient conditions. And a wellprotected brain may act as an index organ of how well organs are perfused and oxygenated.1

INVOS™ technology meets those clinical demands — and more. In fact, no other cerebral oximetry technology is backed by a comparable volume of published, peer-reviewed clinical research.

Reliable and validated characteristics include2:

  • Accurate value based on a good correlation with field saturation (75% venous to 25% arterial ratio)3
  • Optimal sensor spacing of 3 and 4 centimeters2
  • Wavelengths of 730 and 810 nanometers
  • Clinically responsive algorithm2

Order Information


When using the INVOS™ 7100 system, you take a baseline reading on the awake patient before induction or the administration of medications or oxygen – and then monitor the patient for percent changes from baseline.

  • The brain’s normal range is 58-82 points.1,4,5
  • The intervention threshold is when there is a 20% change from the original baseline or when the actual value displayed is below 50 points. 1,4,5
  • A critical threshold is when the value drops 25% from the baseline or there’s an actual value of below 40. 1,4,5
  • The monitor calculates and displays this percent drop from the baseline – once the baseline has been set.



Redesigned user interface

  • Saves time navigating and customising the INVOS™ system monitoring

Touchscreen functionality

  • Saves time when entering and reviewing patient data
  • Allows you to mark events as they occur, simply by tapping the screen

Auto baseline

  • Saves time in the busy OR because no manual setup is required; ensuresthat a baseline is set

Sensor identification

  • Allows quick identification and adjustment of individual sensors

Sensor design

  • Designed to improve adhesion and allow for co-use with BIS™ sensors

Sensor-off detection

  • Automatically alerts you when sensors have become detached


Reduced size and weight

  • 80% of original size and weight so it’s easier to transport with the patient

Tablet-based device

  • Easily transfer the device and its patient data from one care area to the next

Data continuity

  • Allows you to:
    • Look back at the patient’s INVOS™ system values and intervention responses from the previous care area
    • Append data to an existing case


Reduced sensor size

  • BIS™ monitoring sensors fit alongside INVOS™ 7100 system sensors without overlapping

System compatible

  • Tested to ensure that the BIS™ monitoring system and the INVOS™ 7100 system will not interfere with one another
  • Patients can be monitored by both INVOS™ regional oximetry and BIS™ depth-of-sedation at the same time

Product Benefits
