Nidek Nuvo Nano Ultra-Lightweight Portable Oxygen Concentrator (Model 855): A Complete Guide
An American-made, ultra-lightweight pulse-dose concentrator built for ambulatory patients and transport logistics — just 4.7 lbs with battery, Auto-Pulse backup dosing, and FAA approval for commercial air travel.
Ambulatory patients and transport teams need a portable concentrator that’s easy to carry without sacrificing visibility into remaining runtime. The Nidek Nuvo Nano (Model 855) is built around that combination — American-made, ultra-lightweight, and equipped with a clear diagnostic display.
Weighing just 4.7 pounds with battery, the Nuvo Nano delivers breath-actuated pulse-dose oxygen across five settings (210 to 1,000 mL/min) with concentrations reaching up to 96%, backed by an Auto-Pulse backup safety system that automatically delivers pulsed oxygen if breath activity pauses.
Engineered by Nidek Medical Products, Inc.

Who Is the Nuvo Nano Typically Prescribed For?
The Nuvo Nano is best suited to ambulatory patients on a pulse-dose prescription who prioritize minimal carrying weight, as well as mobile care networks and transport logistics teams that need clear diagnostic visibility into remaining runtime. Its Auto-Pulse backup dosing also provides added protection during patient transport if breath activity briefly pauses. As with any oxygen device, the appropriate delivery mode and setting should be determined by your physician based on your specific prescription.
Adding the Nuvo Nano to the EnhDme-Pro catalog gives physicians and facilities an American-made, ultra-lightweight pulse-dose option with strong diagnostic visibility for transport and mobile care use.
Frequently Asked Questions
Can the Nidek Nuvo Nano be used with a bubble humidifier bottle?
No. Humidifier bottles are restricted to stationary continuous-flow systems. Pulse-dose POCs output instantaneous gas boluses on inhalation and cannot build the line pressure necessary to push oxygen through water, which will trigger flow error alarms.
Can the Nuvo Nano operate and recharge in a vehicle?
Yes. The included DC power cable plugs into standard 12V vehicle outlets, allowing the unit to deliver oxygen on all 5 settings while simultaneously charging the internal battery.
What prescription verification is required prior to order dispatch?
Per FDA Class II medical device regulations, orders for the Nidek Nuvo Nano require a valid prescription or medical license specifying pulse-dose oxygen settings prior to compliance verification and shipment release.
