Nidek Nuvo 8 High-Flow Stationary Oxygen Concentrator (Model 585): A Complete Guide
A closer look at the Nuvo 8's high-flow design — built to bridge the gap between standard 5-liter home units and heavy 10-liter systems, with continuous flow up to 8 LPM and quieter, lower-power operation.
Not every patient with a high-flow oxygen prescription needs the electrical draw and noise level of a full 10-liter system. The Nidek Nuvo 8 (Model 585) is built for that in-between range — patients and facilities that need more than a standard 5-liter concentrator can deliver, without stepping all the way up to a heavier high-flow unit.
Delivering continuous-flow oxygen from 2.0 to 8.0 LPM at 90% purity, with an elevated outlet pressure of 17 PSIG and standard integrated purity monitoring, the Nuvo 8 is engineered for long-term care facilities, specialty respiratory care networks, and high-demand home health settings.
Engineered by Nidek Medical Products, Inc.
The Nuvo 8 is manufactured in the United States by Nidek Medical Products, Inc. and is backed by a 3-year limited manufacturer warranty. As a Class II FDA-regulated medical device, it is available strictly by prescription. This listing covers Model 585, which comes standard with Nidek's integrated OCSI oxygen purity monitor — Model 580 does not include this sensor.

Nidek Nuvo 8 High-Flow Stationary Oxygen Concentrator
A high-flow stationary concentrator built to bridge the gap between standard 5-liter units and heavy 10-liter systems. Delivers continuous-flow oxygen from 2.0 to 8.0 LPM at 90% purity, with a 17 PSIG outlet pressure sufficient to drive humidification devices, specialized masks, and longer tubing runs without pressure drop. Comes standard with Nidek's integrated OCSI oxygen purity monitor, a lockable flowmeter dial, a slender tapered cabinet with smooth-gliding casters, and a comprehensive mechanical safety system including a 40 PSIG pressure relief valve and thermal shutoff.

Who Is the Nuvo 8 Typically Prescribed For?
The Nuvo 8 is well suited to mid-to-high acuity patients whose prescribed flow rate exceeds a standard 5-liter concentrator but doesn't require a full 10-liter system — including facilities standardizing 8 LPM beds without taking on the higher electrical draw and noise level of larger units, specialty respiratory care networks, and high-demand home health settings. Its sub-48 dBA operation also makes it a consideration where overnight noise matters. Flow needs vary significantly from person to person — if you're unsure whether this unit fits your situation, that's a conversation for your physician or respiratory therapist.
Adding the Nuvo 8 to the EnhDme-Pro catalog gives physicians and facilities a mid-tier high-flow option between standard home units and full 10-liter systems.
Frequently Asked Questions
What is the difference between Model 585 and Model 580?
Model 585 includes the integrated Oxygen Concentration Status Indicator (OCSI), which continuously measures purity and triggers alerts if oxygen levels drop below therapeutic thresholds. Model 580 lacks this sensor. This post covers Model 585.
How does the 17 PSIG outlet pressure benefit accessory setup?
Standard 5L concentrators operate at roughly 5–7 PSIG. The Nuvo 8's 17 PSIG output provides sufficient pneumatic force to drive humidification devices, specialized masks, and longer cannula tubing runs up to 8 LPM without pressure drop.
What prescription documentation is required before an order ships?
Per FDA Class II medical device regulations, orders for the Nuvo 8 require a valid prescription or medical license specifying continuous-flow oxygen settings prior to compliance verification and shipment release.
