The clinical reference standard in regional oximetry

The more you know about your patients, the more confidently you can care for them.

Regional oximetry can play an important role as a valuable “first alert” because it monitors for hemodynamic changes and deteriorating patient conditions. Using the right monitoring solution can help you identify relevant signals and make more informed clinical decisions.

INVOS™ technology meets those clinical demands. In fact, no other cerebral oximetry technology is backed by a comparable volume of published, peer-reviewed clinical research.([FOOTNOTE=Yu Y, Zhang K, Zhang L, Zong H, Meng L, Han R. Cerebral near-infrared spectroscopy (NIRS) for perioperative monitoring of brain oxygenation in children and adults. Cochrane Database Syst Rev. Jan 17 2018;1(1):Cd010947. doi:10.1002/14651858.CD010947.pub2],[ANCHOR=],[LINK=])

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

  • Monitors the stability of cerebral and peripheral circulations in a noninvasive, real-time way
  • Leverages associations between cerebral and peripheral circulations to better manage care; i.e. whether the periphery appears to be shunting blood flow to preserve the brain
  • Helps clinicians determine whether vascular beds surrounding vital organ areas are adequately perfused
  • Helps clinicians more closely identify and manage regional oxygenation issues in the OR, PICU, NICU, and/or cardiac catheter lab
  • Helps clinicians obtain objective data noninvasively for decision making
  • Intended for patients of any age or weight; with tailored sensors for adults, children, infants, and neonates
