    Inogen One G5 - Prescription Requirement

    Inogen One G5 oxygen concentrators require a valid prescription from an authorized physician to purchase. 

    Inogen One G5 Portable Oxygen Concentrator - Key Features

    Inogen One G5 Oxygen Concentrator - Breath Detection

    The Inogen One G5 offers consumers a Breath Detection Alert Mode similar to that of other Inogen One concentrators. When no breath is detected for more than 60 seconds, this option notifies users visually and audibly. Simply press the bell icon on the device's control panel to enable or disable this feature. As a pulse dose concentrator, the Inogen One G5 can only administer oxygen therapy when the user inhales.

    If no breath is detected after 60 seconds, the concentrator enters an auto-pulse mode, which delivers regular intervals of metered oxygen until the next breath is detected. Once the next breath occurs, the concentrator resumes oxygen delivery at the previous setting.

    During oxygen therapy, a green LED will indicate that the breath has been detected and oxygen delivered.

    Inogen One G5 Portable Oxygen Concentrator - Battery Duration

    A single or dual battery configuration for the Inogen One G5 is available at checkout. At the lowest oxygen levels, a single battery may be used for up to 6 hours while a double battery can be used for up to 13 hours. For a better understanding of the approximate battery life for each oxygen level, see the battery duration chart below.

    To change the battery, simply hold down the battery latch and slide the battery off of the concentrator. Ensure the device is off prior to disconnecting from power.

In the event of external power failure, the battery in the unit will act as a backup power device, providing uninterrupted oxygen therapy. The installed battery will charge while the device is plugged into AC or DC power. An optional external battery charger can be purchased separately.

    When there are 10 minutes of battery life remaining, the oxygen concentrator will sound a low-priority alert (see Safety Features). Plug into an external power source when possible. The remaining battery life will show on the unit’s backlit display screen.
