Nonin Exclusives

Quality Sensors

All pulse oximeters use red and infrared light to measure SpO2 levels. Nonin PureLight sensor technology uses high-quality LEDs and a calibrated receptor to eliminate interference from secondary frequencies.

Low Perfusion Filter

The removal of noise artifacts is crucial for an oximeter to accurately assess SpO2 in low perfusion. PureSAT signal processing technology uses powerful filtering to remove noise from weak or low perfusion signals, providing reliable and accurate readings.

True Pulse Detection

PureSAT signal processing locates the true pulse in motion and low perfusion. This eliminates false readings due to patient motion, reducing the time required to obtain a reliable measurement.

Smart Averaging

Intelligent, automatic averaging helps users save time in fast-paced care environments. PureSAT technology uses a smart algorithm that automatically adjusts for three second averaging or faster.

How It Works

PureLight
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 consistently eliminates variations in readings from patient to patient and sensor to sensor.

PureSAT
Pulse Oximetry Technology

PureSAT 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 uses advanced algorithms to separate pulse signals from artifacts and interference, leaving only the true pulse. Using smart averaging technology, PureSAT automatically adjusts to each patient’s condition to provide fast and reliable1 readings.

Accuracy You Can Count On

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 ±14.4.2

SpO2 Accuracy Through Generated Motion

Nonin’s finger oximeter was able to read through motion. The competitor oximeter gave false high and false low SpO2 readings as compared to the CO-oximeter reference values. The competitor oximeter was unable to read through motion and provided no readings during motion as indicated by gaps in the green chart line.
