Let Somanetics help you cultivate a culture of safety.
Unlike level-of-consciousness monitors, the INVOS® System provides direct, concrete information about cerebral perfusion. This evidence-based tool helps you protect the most salient organ in the body - the brain. Continuous visibility to cerebral oxygen saturation changes allows you to better titrate hemodynamics and anesthesia per patient in real time. This knowledge ensures greater confidence in clinical decision-making and greater control throughout the course of surgery - augmenting your existing vigilance over patient safety.

Cerebral oximetry monitoring with the INVOS® System is a natural extension of the parameters under your watch and in promoting the culture of safety at your healthcare institution. For more than a decade, Somanetics has been dedicated exclusively to noninvasive regional oximetry, and this specialization has resulted in an unparalleled depth of expertise. It is the clinical reference standard in cerebral/somatic oximetry with more than 600 clinical presentations, study abstracts and published papers. More importantly, it has been shown to improve patient outcomes.
Perhaps that's why 1,200 global installs and 700+ U.S. hospitals have added the INVOS® System to their care regimen.
Monitoring Offers Specific Benefits to Anesthesiologists
The list is long on INVOS® System benefits and anesthesiologists are seeing the value first hand with their patients. Here are several advantages you'll receive when you incorporate cerebral oximetry into your standard operating procedure:
- Broad applicability: Used in cardiac, general and vascular surgery and on adult, pediatric and infant/neonatal patients.
- Independent assessment: Adds critical guidance during deep hypothermia and circulatory arrest because it is not pulse, pressure or temperature dependent.
- Flexible monitoring: Choice of two or four data channels provides cerebral oximetry, somatic oximetry or both simultaneously; may also be used in tandem with level-of-consciousness monitors, TCD and EEG.
- Customized care: Allows each patient to serve as his/her own control, so decisions are tailored to the patient's unique physiology and baseline values for optimal care in all situations.
- Early intervention: Helps you optimize care during surgery by helping you detect and correct potentially harmful oxygen deficiencies before they escalate.
- Seamless integration into OR: The INVOS® System can attach via swivel arm to your existing anesthesia machines and perfusion pumps, or to its own compact rolling stand.
Fill the Void of Traditional Vitals
Conventional methods such as blood pressure, pulse oximetry and urine output are all indirect indices of brain oxygenation. Because they are whole-body metrics, data has shown they often lack the ability to identify site-specific ischemia in real-time. The same premise holds for lab tests that are invasive, intermittent and time-delayed views of oxygenation. And while EEG and TCD do provide direct cerebral measures, they do not measure oxygenation, per se.
Perhaps most importantly, rSO2 has been shown to be predictive of and improve outcomeSomanetics 1-5. Additionally, studies show it provides unique clinical data and benefits, not merely a confirmatory measure of other modalities Somanetics 3,6-9 (e.g., ICP, TCD, EEG, CPP and SEP). For example a studySomanetics 6 from the University of Louisville School of Medicine showed that rSO2 was predictive of cerebral oxygenation problems twice as many times as other modalities. In this study, neuromonitoring modalities detected the need for interventions in 93% of cases. Of this, rSO2 identified the need 56% of the time, followed by TCD at 28% and EEG at 9%.
The INVOS® System provides an opportunity to augment these traditional vital signs by providing continuous, noninvasive, real time, site-specific saturation data on the brain and body.
