The clinical reference standard in regional oximetry

INVOS™ adult rSO2 sensors are used with the INVOS™ 7100 regional oximeter to noninvasively monitor site-specific adequacy of perfusion in the brain or body tissue directly beneath the sensors. This enables you to obtain real-time data on regional oxygen saturation (rSO2), which can detect site-specific ischemic complications even when systemic parameters or lab tests are within normal limits.([FOOTNOTE=Casati A, Fanelli G, Pietropaoli P, et al.

INVOS™ adult rSO2 sensors are applied to the skin’s surface and can be applied on up to four site-specific areas chosen by the care team. The sensors are user and patient friendly, making monitoring of ischemic threats to the brain and body safe and easy, while supplying the information the care team needs to assess and intervene accordingly.


  • Uses 4 wavelengths: Two for trending and two for sensor off detection
    • 730 nm and 810 nm wavelengths used for trending values
  • Same trusted algorithm with a 25:75 arterial/venous ratio
  • Has a smaller footprint compared to INVOS™ 5100C adult sensors
    • Tested for co-use of BIS™ and INVOS™ without interference with one another
  • Perforations help keep sensor in place when patient perspires
  • Sensor identification allows for quick identification and adjustment of individual sensors
  • Not made with DEHP or natural rubber latex – BPA free

Uses medical grade acrylic adhesive and is packed non-sterile for single use.

Regional oximetry is an adjunctive technology that should not be used as the sole basis for diagnosis or clinical decision-making.
