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 artifact 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 or alarms due to patient motion, reducing the time required to obtain a reliable measurement.
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.
PureLight LEDs produce a high-intensity pure light spectrum.
PureLight sensor receptor eliminates variations in readings.
PureSAT signal processing filters out artifacts and interference to show the true pulse.

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 ±14.4.1
