The Nidek Nuvo Lite Mark 5 is a 5-liter oxygen concentrator that separates oxygen from ambient air, delivering it at a prescribed purity level (typically 93% ± 3%) for patients who require long-term oxygen therapy (LTOT).

Key Features & Specifications

1. Oxygen Output & Purity:

   • Flow Rate: Delivers up to 5 liters per minute (LPM) of oxygen.

   • Oxygen Purity: Maintains a consistent purity of 93% ± 3% across the entire flow range (1L to 5L). This is the medical standard for therapeutic oxygen.

2. User-Friendly Operation:

   • Simple Control Knob: Features an intuitive, easy-to-turn flowmeter knob to set the precise liter flow as prescribed by a doctor.

   • Clear Flow Indicator: A ball-in-tube or similar gauge provides a clear visual confirmation that oxygen is flowing.

   • Pressure Gauge: Monitors the internal operating pressure of the device.

3. Safety and Alarm Systems:

   • Audible Alarm: Built-in alarms to alert the user in case of:

     • Power failure

     • Low oxygen purity

     • System malfunction

   • Optional Oxygen Concentrator: The unit may include an optional oxygen concentration monitor that displays the real-time purity level.

4. Design and Functionality:

   • Quiet Operation: Engineered for low noise levels, making it suitable for use in bedrooms and living areas without significant disruption.

   • Durable Construction: Built with a robust chassis for long-term, reliable home use.

   • Castor Wheels: Equipped with wheels and a handle, making it moderately portable within the home (e.g., from the bedroom to the living room).

   • Accessories: Typically includes a standard oxygen outlet, compatible with various oxygen tubing and humidifier bottles.

5. Technical Requirements:

   • Power Consumption: Designed to be energy-efficient. It plugs into a standard household power outlet.

   • Input Power: Usually operates at 220V-240V (depending on the regional model).

   • Filters: Includes multiple filters (e.g., Intake Filter, Bacterial Filter) to ensure clean intake air and sterile output, which require regular cleaning or replacement.

Benefits and Advantages

• Reliable Oxygen Supply: Provides a continuous, on-demand source of medical-grade oxygen, eliminating the need for oxygen cylinder deliveries and the risk of running out.

• Cost-Effective: After the initial purchase, the ongoing cost is primarily electricity, making it significantly cheaper than relying on oxygen cylinders in the long run.

• Promotes Independence: Allows patients to remain active within their homes, improving their quality of life.

• Safety: Built-in alarms provide critical safety warnings, giving peace of mind to both the user and their caregivers.

• Ease of Use: The simple design makes it easy for elderly users or those with limited technical knowledge to operate.
