Cerebral and Somatic Oximetry is Gaining Traction as a Way to Protect Your Most Vulnerable Patients

Physicians around the world are turning to cerebral/somatic oximetry as a means of identifying circulatory inadequacy in critical organ systems.

Nonin Medical’s neonatal and pediatric cerebral and somatic oximetry monitoring system offers absolute accuracy in the widest range of neonatal and pediatric clinical patients. Indicated for cerebral and somatic use in all patients weighing less than 40kg, the system aids the clinical care team with vital information in key tissue beds-enabling clinicians to quickly assess intervention needs.

Why Nonin EQUANOX neonatal and pediatric sensors?

The EQUANOX 8004CB and 8004CB-NA Neonatal/Pediatric Sensors were designed to be used in a variety of clinical settings. More...

Some settings include operating room, the neonatal intensive care unit and the pediatric intensive care unit. Select features of the EQUANOX Advance Neonatal/Pediatric Sensor Model 8004CB Series include:

  • Cerebral and Somatic Monitoring – Up to four-channel monitoring on one screen.
  • Absolute Accuracy – Not just trending accuracy; with Absolute Accuracy clinicians can trust and act on the saturation parameters provided.
  • Dynamic Compensation* Algorithm – A revolutionary new algorithm enhancement that automatically adjusts for the varying light-scattering properties of neonate/infant brains at varying stages of myelination.
  • Pediatric-Specific Spacing of Light Emitters and Detectors – Designed specifically for patients weighing less than 40 kg with varying levels of myelination.
  • Consistency and Reliability – Rapid, reliable response to change without signal instability and interruptions from ambient electrical and optical interference.

Technology designed specifically for neonatal and pediatric patients

Nonin’s exclusive EQUANOX technology reduces inaccuracies caused by light scattering effects from non-target tissue.  More...

Dual emitters and dual detectors in the EQUANOX Advance sensor create pairs of reflected light paths through surface tissue and through the cerebral cortex, producing measurements that are minimally affected by intervening tissue or surface effects.

Four-wavelength algorithms translate light information into accurate measurements.

The light absorption information collected by the dual emitter/detector architecture is automatically incorporated into Nonin’s Dynamic Compensation light processing algorithm, to provide real tissue oxygenation saturation values based on the patient’s unique brain development characteristics.

Dual emitters. Dual detectors. A singular breakthrough in neonatal and pediatric cerebral/somatic oximetry.


Only Nonin EQUANOX uses two emitters and two detectors to provide cerebral cortex measurements that are minimally affected by intervening tissue or surface effects.

A real-time measurement.

The EQUANOX Advance signal processing data provides the actual percent of oxygenated hemoglobin in the target tissue for display on the monitor.

Introducing Nonin Medical’s Dynamic Compensation*

The EQUANOX System is the first oximetry algorithm to automatically account for developing neonatal/pediatric brain tissue.  More...

The optical properties of brain tissue change significantly during the first few months of life. The EQUANOX Advance Cerebral/Somatic Oximetry System effectively isolates targeted tissue and automatically takes into account the light attenuation changes caused by myelination variation, providing you with data you can act on.

To measure blood oxygen saturation levels, cerebral and somatic oximeters must separate the optical effects of blood from tissue.

Myelination development changes the optical properties of the pediatric brain and can vary from patient to patient


Cerebral/somatic oximetry designed specifically for neonatal/pediatric patients

The EQUANOX Advance 8004CB Series sensor has been designed from the ground up as a solution for neonatal/pediatric patients, More...

featuring light emitter/detector spacing that has been engineered and tested for neonate/infant/pediatric patients. This light path spacing is designed to reach, but not pass through, the vascularized cerebral cortex.

EQUANOX Advance 8004CB-NA Sensor


Whereas other cerebral oximetry systems require clinicians to enter information such as age and weight in order to obtain approximate brain development, Nonin’s Dynamic Compensation algorithm makes this step unnecessary and provides confidence that the data is patient specific. You simply place the sensor and instantly see the values. The displayed signal refreshes every 1.4 seconds; so, if the tissue saturation is changing, you will see it quickly.
