Nonin Onyx Vantage 9590 Finger Pulse Oximeter

The Onyx Vantage 9590 is a sealed fingertip pulse oximeter for spot checks of SpO2 and pulse rate on adults and children with fingers 0.8 to 2.5 cm thick. It runs on two AAA cells, switches on when a finger is inserted, and shows signal quality on a three colour LED. It has no alarms, is not repairable in the field and needs no calibration beyond battery changes.

Safety

Safety warnings from the record.

  • No audible alarms: for spot checks only. Source
  • Do not use in MRI, in explosive atmospheres or on neonates. Source
  • Readings can be degraded by motion, bright light, nail polish, dyes, carboxy or methaemoglobin, anaemia and a cuff or line on the same arm. Source
  • Check the finger site at least every 4 hours if left on, and avoid extra pressure on the sensor. Source
  • Keep phones and radios at least 30 cm away, and expect interference from electrosurgery. Source

Where this note comes from.

Not covered: No FDA recall names the 9590; Nonin's four recalls cover other models. MAUDE counts filtered by model number 9590 appear to mix in unrelated devices (several are lab test result codes), so no MAUDE trend is given. The 9590's own 510(k) summary (K112843) was not opened; the clearance date is taken from a later Nonin summary. The 'housing seals and optics' entry reflects manual cautions, not failure data.
