Accuracy You Can Act On

A study comparing the accuracy in motion of a Nonin Medical pulse oximeter with PureSAT^® technology and a competitor pulse oximeter was conducted at a leading hypoxia research laboratory. Accuracy was determined using an industry standard breathe-down protocol of induced hypoxia in thirteen subjects. SpO₂ values are compared to the gold standard which is CO-oximetry analysis of arterial blood samples. Motion was generated using a mechanical fixture with tapping and rubbing.

Nonin oximetry with PureSAT technology was found to have superior accuracy. Nonin precision was ±2.1; competitor technology precision was ±14.4.¹

Accuracy You Can Count On

The Nonin finger pulse oximeter with PureSAT technology accurately tracked the subjects’ desaturation and had an outstanding correlation with the CO-oximeter. In addition, 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.

Oximeters tested: Nonin finger pulse oximeter with PureSAT technology (made in USA); competitor finger pulse oximeter manufactured by Beijing Choice Electronic Technology Co., Ltd. (made in China).
