INVOS™ (In Vivo Optical Spectroscopy) Technology for OEM Monitoring Solutions

INVOS™ (In Vivo Optical Spectroscopy) system technology noninvasively monitors site-specific adequacy of perfusion in the brain or body tissue directly beneath its sensors. With its clinically validated design and capabilities and patented sensor spacing configuration, INVOS™ technology demonstrates sensitivity to subtle changes in saturation and blood flow.¹ This arms clinicians with 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.^2,3,4,5

• Uniquely designed sensors—designed for adult, pediatric and infant/neonatal patients—are placed directly on the desired monitoring site.
• Two specific wavelengths of near-infrared light (730 and 810 nm) are used to determine the oxygen-hemoglobin saturation in the tissue beneath the sensors.
• Two detectors (shallow and deep) are spaced to permit separate data processing of shallow and deep optical signals, enabling clinicians to localize the area of measurement, called spatial resolution.
• Unlike parameters that measure only venous or arterial blood, INVOS™ technology includes contributions from both in a 3:1 ratio, yielding a venous-weighted percent saturation. This provides real-time data about the balance or imbalance of oxygen supply and demand, thus reflecting venous oxygen reserve—the oxygen remaining after extraction by tissues and vital organs — and providing accurate measurement of site-specific tissue oxygenation.
• INVOS™ technology uses settings for patient-specific baselines and thresholds, enabling clinicians to monitor oxygenation changes from baseline
