Nonin 9590 Overview
Nonin Onyx Vantage 9590 Finger Pulse Oximeter is designed to provide quick readings for pulse rate and SpO2. This pulse oximeter uses patented technology to provide safe and noninvasive readings with near-immediate results. The LED screen will flash green, yellow, or red depending on the pulse quality. If the reading provides a yellow or red light, a second attempt should be taken on another finger to get a better pulse signal. Nonin Onyx Pulse Oximeter can provide up to 6,000 spot checks or 36 hours of continuous operation before the two AAA batteries (included in the purchase) require changing.
The clinician-facing LED screen is bright, large, and easy to use, making this a user-friendly option for various people. The water-resistant and exceptionally durable casing makes for a very dependable device. Nonin Pulse Oximeter 9590 includes a lanyard and carrying case for total convenience. With a four-year manufacturer warranty, this device is designed to sustain long-term use. Pair with an Escali Infrared Forehead Thermometer to be prepared for an even wider range of biometric readings.
Versatile and Efficient
Onyx Oximeters are designed for use with a wide range of patients, from pediatric to adults. It's not made with natural rubber latex, making it a great option for a wide range of users.
Durable Construction
Nonin Onyx 9590 is made with a durable protective casing with water-resistant capabilities, protecting it from drops and water spills. The oximeter uses a unique Pulse Quality Indicator that provides a quick assessment of the pulse reading quality. This notifies the user through color-coding: green light representing a good reading, yellow representing a fair reading, and red representing a poor reading. Not only does this minimize training time, but it also gives the user insight into the quality of the reading and assures a consistent and effective process.
Safe and Noninvasive
Nonin Onyx Vantage 9590 Pulse Oximeter is manufactured in the United States using a lead-free construction for optimal user safety. The fingertip design simply and comfortably clips over the finger for an effective reading through completely non-invasive means.
Nonin PureSAT Technology
Nonin PureSAT Signal Processing Technology is patented and clinically proven technology that uses intelligent pulse-by-pulse filtering. This technology was designed to withstand the presence of motion, low perfusion, or other difficulties that can lead to less accurate readings. PureSAT uses advanced algorithms that separate the pulse signals from artifact and interference, allowing the readings to sift through potential false readings and find the precise results. This technology automatically adjusts to each patient's condition to ensure rapid and reliable readings.
