Description
When accuracy, speed, and durability are non-negotiable in clinical care, the Onyx Vantage 9590 Fingertip Pulse Oximeter by Nonin Medical stands out as the ultimate choice for healthcare professionals. Built to meet the rigorous demands of hospitals, emergency medical services, home care, and clinical trials, this medical-grade blood oxygen monitor delivers fast, highly reliable SpO2 and pulse rate measurements across a comprehensive range of patient populations and clinical conditions.
Powered by Nonin’s patented PureSAT® SpO2 signal processing technology, the Onyx Vantage 9590 Fingertip Pulse Oximeter filters out ambient interference, motion artifacts, and low-perfusion signals. This guarantees that clinicians receive immediate, actionable data even when measuring challenging patients, such as individuals with cold extremities, dark skin pigmentation, or weak peripheral pulses. Designed for universal versatility, the device automatically adjusts to accommodate a wide spectrum of finger sizes ranging from 8 mm to 25.4 mm (0.3 to 1.0 inches), seamlessly transitioning between pediatric and adult patients without requiring separate sensors or adapters.
Usability and energy efficiency are core highlights of this device. With no manual power buttons to press, the unit activates automatically upon finger insertion, streamlining spot-checks in high-pressure medical environments. Its bright, high-contrast LED display ensures optimal visibility from any angle and under all lighting conditions, whether in pitch-black rooms or bright sunlight. A dynamic three-color LED pulse quality indicator (green, yellow, red) offers real-time feedback on signal strength, allowing practitioners to assess measurement validity instantly.
Engineered and manufactured in the United States, the unit offers extreme durability with drop-tested casing and resistance to water ingress, enduring thousands of spot-checks in harsh daily operations. Operating on just two AAA batteries, it provides up to 6,000 spot-checks or 36 hours of continuous performance. Lightweight at under 57 grams, it comes complete with a lanyard, instruction CD, and batteries for immediate deployment.
