The Nidek Mark 5 Nuvo Lite Home Oxygen Concentrator is an ultra-compact home concentrator unit. Its durable exterior and made-to-last parts, along with the sturdy handle and lockable castors, make it easy to transport from room to room. The Nuvo Lite is a continuous flow oxygen concentrator, meaning it constantly delivers oxygen to the patient. This home oxygen device can deliver up to 5 liters of oxygen per minute, and can reach oxygen purity in under three minutes. It’s reliable, quiet design makes it a reputable choice for those that require supplemental oxygen.

Like all oxygen concentrators, the Nidek Mark 5 Nuvo Lite requires a prescription from a licensed physician. Prior to purchasing, consult your doctor to see if supplemental oxygen is right for you.

Nidek Mark 5 Nuvo Lite Home Oxygen Concentrator Features

The Nidek Mark 5 features 12 unique oxygen delivery systems, ranging from 0.125 LPM to a maximum output of 5 LPM. No matter the individual needs, this oxygen concentrator delivers. To change the amount of oxygen delivered, users can simply turn the flow control valve on the intuitive control panel of the device. A humidifier bottle can be attached to the unit for users who experience dry nasal passages or who live in drier climates.

LED indicator lights on the display panel indicate the oxygen concentrator’s operational status: a green LED indicates the device is ready for use, while a red light indicates a system fault. The operating volume of the Nuvo Lite is around 40 dBA, roughly the volume of a library. As the Nuvo Lite is a home oxygen concentrator, it does not need to be connected to a battery for external power. It averages approximately 330W in power consumption.

Connecting the Humidifier with Nidek Mark 5 Nuvo

Individuals who require humidification are able to attach a humidifier bottle to the back panel of the Nidek Mark 5. After filling the bottle to the max fill line, screw the lid on securely and attach to the unit using the provided straps. Attach the tubing from the lid of the humidifier to the oxygen output valve on the concentrator. As a final step, connect your oxygen tubing to the output valve on the humidifier and ensure you can feel the flow of oxygen from your nasal cannula. Reference the user manual for assistance if necessary.

How Does the Nuvo Mark 5 Nuvo Nidek Mark 5 Stationary O2 Concentrator Work?

The air that enters the Mark 5 Nuvo Lite Oxygen Concentrator is filtered by an external cabinet air filter and then passes through the suction tube and fine filter. The suction sound of the compressor is silenced by the suction tube. The pressurized air coming from the compressor goes to a pair of 3-way solenoid valves through a heat exchanger. The purpose of the heat exchanger is to reduce the temperature of the compressed air. The nitrogen is then extracted from the air so that the device can deliver only the high purity oxygen by passing the air through the sieve beds that contain molecular sieve.

Starting Up/Installation of Nidek Mark 5 Nuvo Lite Oxygen Concentrator

      • Use oxygen treatment that is delivered indirectly. Check to see whether the switch is turned off.
      • For usage in the absence of a humidifier The cannula is connected directly to the concentrator oxygen product output through the bottle.
      • Simply place the cannula over the oxygen outlet and slide it in place.
      • Remove the lid from the humidifier bottle and fill it with water according to the manufacturer's instructions. Connect the oxygen concentrator to the bottle and reattach the cover. Attach the bottle to the concentrator using the connection straps as directed.
      • To avoid leaks, double-check that all of the pieces are properly linked.
      • Connect the power cord to a power outlet that has the proper voltage and frequency as specified on the manufacturer's technical label.
      • Turn the power switch (I/O) to ON (I). The green indicator light illuminates, signaling the presence of electricity.
      • Note: Within five minutes of turning on the device, the requisite oxygen concentration is usually achieved.
      • Set the flow control knob to the desired setting. It's possible that this knob has previously been locked in the medically recommended position. In this scenario, resist the urge to force it. It can only be released by the technician or medical staff.
