The Nonin Onyx Vantage 9590 is the preferred digital pulse oximeter of medical professionals in many different fields, including primary care physicians, first responders, dentists and emergency rooms. As the newest member of the Nonin line of digital pulse oximeters, the 9590 is easy to use and provides quick and accurate blood oxygen saturation levels and pulse readings to individuals with medical conditions such as sleep apnea and COPD. The durable construction of the Onyx Vantage 9590 also makes it the ideal choice for sports enthusiasts who regularly attain higher than average altitudes, including skiers and rock climbers.

The Nonin® Onyx Vantage 9590 Finger Pulse Oximeter is a small, lightweight, portable device indicated for use in measuring and displaying functional oxygen saturation of arterial hemoglobin (%SpO2) and pulse rate of patients, who are well or poorly perfused, during both motion and non-motion conditions. It is intended for spot-checking of adult and pediatric patients on fingers, including the thumb, that are between 0.3 - 1.0 inch (0.8 - 2.5 cm) thick. Alternatively, the Onyx Vantage 9590 may be placed on a toe of a patient during non-motion conditions. The device's intended use environments include hospitals, clinics, long-term care facilities, skilled nursing facilities, emergency medical services, and home healthcare services.

Concord Health Supply is pleased to offer this scientifically proven product that is made in the U.S. with latex-free and lead-free construction for your safety. The Onyx Vantage 9590 provides a high level of performance that will ensure accurate readings for an extended period of time. In fact, one set of two AAA batteries will enable you to receive 6,000 spot checks or to leave the unit continuously running for 36 hours. The Onyx Vantage 9590 works with almost all finger sizes, and it is also effective with dark skin tones and patients who have low perfusion.

Best pulse oximeter.
I have had my pulse oximeter since I graduated as an RRT in 2017. My pulse ox finally gave out. So sad but I'm back to purchase another.

Accuracy Is The Key
There aren't a lot of whistles and buzzers with this pulse Oximeter, but if you want truly accurate readings, this is the device. As we age, the accuracy is most important. I also love the 4 year warranty. My previous, less accurate device barely lasted 2 years and had the standard 90 day warranty.
