    Inogen One G4 Portable Oxygen Concentrator Features

    Inogen G4 Oxygen Output

    The Inogen One G4 provides oxygen therapy via pulse dose. Like other portable oxygen concentrators, oxygen is only delivered when the unit detects a user inhales. Oxygen does not flow from the unit during exhalation. There are 3 pulse settings on the Inogen G4 concentrator. The setting you use will be determined by your doctor’s prescription. Do not change your device’s settings before first consulting your doctor.

    Inogen G4 Battery Information

    At checkout, users have the option of selecting the standard or extended battery configuration for the G4 oxygen concentrator. With the extended battery, the Inogen One provides up to 5 hours of oxygen therapy at a pulse setting of 1. To determine the best battery based on your prescription, view the chart below.

    In addition to the battery, the Inogen One G4 comes with both AC and DC power, allowing you to charge your device wherever you are. Simply plug the unit into a known working electrical outlet or the cigarette lighter in your car. A battery icon with a lightning bolt will display on the screen to let users know that it is working. Patients can still use the portable oxygen concentrator while it is charging.

    Inogen G4 Upgraded Control Panel

    The Inogen One G4 features a backlit LCD screen as well as four large push buttons, making oxygen therapy as easy as possible. The larger text makes it easier to check your concentrator’s flow settings, while the battery life is displayed numerically. In addition to the LCD screen, the Inogen One G4 also features two LED indicators - one for breath detection and the other for alerts or changes in operating conditions. A flashing LED indicates a higher priority alert.

    Inogen G4 Breath Detection Alert Mode

    In addition to the updated display, the Inogen One G4 provides users with a dedicated button for the Audible Breath Detection Alert Mode. If the G4 does not detect a breath for more than 60 seconds, it will automatically pulse oxygen at a metered rate. Once a breath is detected, the device will return to its normal delivery mode.

    This button allows users to be audibly alerted when the concentrator enters this mode.

    Inogen G4 Oxygen Concentrator Offers Silent Treatment

    Inogen One G4 offers almost completely silent treatment. The absence of a motor means that the machine doesn’t make any noise while the dose is being prepared. However, it isn’t completely silent. There are audio signals to indicate that the therapy is complete.

    Inogen G4  G4 Offers Up to 30 Treatments

    The Innospire One G4 has a powerful battery backup that can be used for 120 minutes or 30 treatments per charge. The battery can be charged with the AC power adapter.

    Inogen G4 Concentrator Requires Minimal Maintenance

    As with the Inogen One G3, the G4 concentrator does not require much in terms of maintenance. If the device itself becomes dirty, wipe it down with a damp cloth and mild detergent. Before wiping it down, make sure it is not plugged into any power source. The particle filters on the Inogen One G4 should be removed and cleaned weekly. To clean them, simply wipe them down with a damp cloth and a mild detergent. Make sure they are completely dry before inserting them into the unit.

    Nasal cannulas should be replaced on a regular basis. For best performance and breath detection, do not use tubing greater than 25 feet in length.

    How to Understand the Battery Level Indicator in Inogen One G4

    • The Battery Level Indicator on the Inogen One G4 works in the following 3 ways:
    • Solid Green LED: Indicates the battery has sufficient charge.
    • Solid Amber LED: Indicates the battery is low and only one treatment is possible.
    • LED Flashing Amber: Indicates not enough charge for treatment.

    How to Charge the Inogen One G4 Battery?

    A socket is provided at the back of the Inogen One G4 where the power adapter is connected.

    Plug one end of the charger into the back of the portable nebulizer and the other end into the wall socket.

    When you switch on the button on the wall socket the LED on Inogen One G4 will flash Green.

    The LED will become Solid Green when the battery is full. When this occurs, switch off the wall socket button and unplug the adapter from both ends.

    It is FAA cleared for usage during flights, cruise ships, and other forms of transportation.
