See the Difference - Performance Comparison Three finger pulse oximeters and one tabletop pulse oximeter were attached to a subject who was breathing for the first minute using a commercially available rebreather* to induce hypoxia. The chart below illustrates that over the course of the test, only the Nonin pulse oximeter, with PureSAT® technology, and Nellcor™ pulse oximeter accurately tracked the subject's desaturation down to 81-82% SpO2 and back up to 96% SpO2. Nonin Nellcor Oximeter A Oximeter B SpO2 Values Over Time Only Nonin and Nellcor™ pulse oximeters accurately tracked the subject's desaturation. Noni n Nellcor Oximeter A Oximeter B *In this test, to induce hypoxia, the subject utilized a commercially available rebreather. The simulator removes CO2 from exhaled air and lowers the oxygen content of air inhaled by the user. Prior to using these devices, please review the Instructions for Use.
