Cerebral/Somatic Oximetry Solutions for Accuracy You Can Act On

Nonin’s proprietary EQUANOX™ regional oximetry technology offers real-time management of patients at risk for compromised oxygen saturation to the brain or other tissues. Accurate measurements of regional oxygenation (rSO2) provide clinicians with information needed to ensure patients receive appropriate intervention during surgery and in critical care settings.

The SenSmart Model X-100 Universal Oximetry System and the EQUANOX Model 7600 Regional Oximetry System both utilize the EQUANOX regional oximeter sensor technology for absolute accuracy that reduces the need to establish a patient baseline and provides values you can act on with confidence.

Using patented near-infrared spectroscopy (NIRS) technology, both the SenSmart Model X-100 Universal Oximetry System and the EQUANOX Model 7600 Regional Oximetry System detect changing levels in cerebral or somatic oxygenation, allowing clinicians to react before injury occurs. Our near-infrared optics and sensor architecture deliver greater accuracy and consistency than conventional NIRS cerebral technologies and provide stable, rapid and reliable signals by minimizing ambient light and electronic interferences.1 In addition, Nonin offers a range of EQUANOX Advance pediatric and adult sensors designed with optical spacing that isolates and targets key tissues for the intended population.

Unique Dual-Emitter/Dual-Receiver Sensor Architecture and Four-Wavelength Accuracy

Compared to traditional NIRS trending technology,EQUANOX Advance sensors are absolute, providing enhanced accuracy in rSO2 measurements on your most challenging patients, regardless of age, weight or skin color -- no more guessing or over-treatment if patients do not read, or read inaccurately. With EQUANOX Advance sensors, if rSO2 values are below 60%, it is a clear indication that a patient may be in a critical oxygen reserve condition and immediate intervention should be considered.

Older NIRS technology claim to be absolute, but clinician confidence suffers when the technology could not read some patients or is impacted by ambient light or electronic interferences. In a recent series of 50 healthy adults, EQUANOX Advance sensors captured data on all subjects, regardless of age, gender, body type or skin color, while 5% of subjects did not read using other technologies.6 In the graphs A and B (below), conventional trending technology is in graph A and EQUANOX Advance is in graph B. Graph B represents the general alignment of data observations of both EQUANOX Advance-reported rSO2 values (blue) and invasive blood-draw-derived SavO2 values (orange) at room air.3,4

Unlike competitors' regional oximetry sensors, Nonin's EQUANOX Advance sensors for pediatric and adult patients feature the proven repeatability and consistency of our patented dual-emitter, dual-receiver sensor architecture.5 This unique sensor architecture effectively targets the cerebral cortex, eliminating surface artifacts that interfere with measurement accuracy.1,2

EQUANOX Advance sensors utilize four wavelengths of light to measure the balance of oxy- and deoxy-hemoglobin, while compensating for tissue factors that reduce rSO2 accuracy. The result is highly accurate measurements of patients’ true arterial and venous saturation illustrated in Graph C below.
