Nonin Onyx® Vantage 9590 Finger Pulse Oximeter
The Nonin Onyx® Vantage 9590 is a professional fingertip pulse oximeter designed for fast and reliable spot-checking of blood oxygen saturation (SpO2) and pulse rate. Compact, lightweight and easy to operate, it is suitable for adult and paediatric patients across hospitals, GP surgeries, clinics, emergency medical services, care environments and home healthcare.
Featuring Nonin PureSAT® technology, the Onyx Vantage 9590 uses intelligent pulse-by-pulse processing to provide reliable readings across a wide range of patients, including those with low perfusion and diverse skin pigmentations. The bright clinician-facing LED display clearly presents SpO2 and pulse rate readings, while a three-colour pulse quality indicator provides a quick visual assessment of signal quality.
