Nonin Onyx® Vantage 9590 fingertip pulse oximeter delivers fast, accurate SpO₂ and pulse rate spot checks using PureSAT® technology, designed for durable, reliable use across clinical and homecare settings.
Fingertip Pulse Oximeter
The Nonin Onyx Vantage 9590 is a compact, lightweight fingertip pulse oximeter designed to measure and display functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate in both well-perfused and poorly perfused patients. It is intended for adult and pediatric
spot-checking on digits (including fingers, thumbs, and toes) across multiple care environments such as hospitals, clinics, long-term care facilities, skilled nursing facilities, EMS services, and home healthcare.
The device provides accurate readings across diverse skin pigmentations and maintains reliability even under low perfusion conditions.
Powered by Nonin PureSAT® technology, the Onyx Vantage 9590 delivers quick, precise SpO2 and pulse rate measurements.
The unit offers up to 6,000 spot checks using two AAA batteries and comes with a 4-year warranty, supporting long-term use in clinical and home settings.
Engineered for resilience, the Onyx Vantage 9590 is designed to withstand 50 drops from a one-meter height. With high battery efficiency and strong construction, it provides dependable value for both clinicians and patients.
The fingertip pulse oximeter produces fast, accurate, and cost-effective spot checks for pediatric and adult patients. PureSAT® automatically adapts to patient conditions, ensuring stable readings even in challenging measurement environments.
Unregulated devices may show inconsistent readings for individuals with darker skin tones or low perfusion. Since 1986, Nonin has focused on developing accurate, validated fingertip oximeters suitable for a broad range of skin pigmentations.

1. Can this device be used on both adults and pediatrics?
- Yes. It is intended for adult and pediatric spot checks on digits with a thickness of 0.3–1.0 inch (0.8–2.5 cm).
2. How long can I wear this device continuously?
- The Onyx Vantage 9590 is recommended for short-term spot-checking and not for settings where motion is expected or where monitoring exceeds 30 minutes.
