Advanced Technologies from Nonin
PureSAT® Pulse Oximetry Technology
Our clinically proven PureSAT® pulse oximetry technology uses intelligent pulse-by-pulse filtering to provide precise oximetry measurements—even in the presence of motion, low perfusion or other challenging conditions.
PureSAT® signal processing reads the entire plethysmographic waveform and pre-filters the pulse signals. Advanced algorithms then separate the pulse signals from artifact and interference, leaving only the true pulse. Using smart averaging technology, PureSAT® automatically adjusts to each patient’s condition to provide fast and reliable readings.
PureLight® Pulse Oximetry Sensor Technology
Pulse oximetry sensors use red and infrared LEDs to measure deoxygenated and oxygenated hemoglobin. LED contamination can affect the oximeter calibration, resulting in inaccurate SpO2 readings below 80%. Nonin sensors use PureLight LEDs, which produce a high-intensity pure light spectrum that eliminates variations in readings from patient to patient and sensor to sensor.
Nonin Sidestream Capnography Technology
Sidestream capnography technology from Nonin eliminates the need for calibration or auto zeroing during patient monitoring. This allows fast, first-breath detection of EtCO2—an indicator of breathing irregularities. Waveform trend monitoring helps verify endotracheal tube placement while a unique moisture management solution helps prevent occlusion.
SenSmart® Regional Oximetry Technology
Nonin SenSmart regional oximetry technology features a dual emitter/dual receiver sensor architecture and four wavelengths of light to deliver consistently accurate rSO2 signals. Our SenSmart X-100 Universal Oximetry System delivers both pulse and regional oximetry measurements, and is designed to accommodate more parameters in the future.
The PureLight® Principle
High-intensity pure light prevents contamination from secondary spectrum emissions
PureLight Red LED (transmits red wavelengths)
Absorption rate provides measurement of deoxygenated hemoglobin
PureLight Infrared LED (transmits infrared wavelengths)
Absorption rate provides measurement of oxygenated hemoglobin
Receptor calibrated for transmission from PureLight sources
Eliminates variations in readings from patient to patient and sensor to sensor
PureSAT Technology in Action:
Elimination of False Alarms Due to Patient Movement
A comparison of Nonin PureSAT® technology with conventional oximetry during a patient movement event shows that PureSAT signal processing locates the true pulse in motion.
Induced Hypoxia and Motion
A leading hypoxia research laboratory compared accuracy in motion between a Nonin Medical pulse oximeter with PureSAT® technology and a competing pulse oximeter. Hypoxia was induced in 13 subjects using an industry standard breathe-down protocol, and motion was generated using a mechanical fixture with tapping and rubbing. SpO2 values were compared to CO-oximetry analysis of arterial blood samples. Nonin precision was ±2.1; competitor technology precision was ±14.4.
Minimizes Surface Tissue Artifacts
SenSmart rSO2 technology uses dual emitters, dual detectors, and four wavelengths of light to measure the balance of oxyand deoxy-hemoglobin. This exclusive technology also compensates for tissue factors that reduce rSO2 accuracy. The result is highly repeatable and accurate measurements of patient tissue oxygen saturation, minimally affected by intervening tissue or surface effects.
