Consider Your Portable Oxygen Concentrator Battery Options

Each Inogen® model is quiet to ensure you can carry on conversations, watch TV or read the newspaper. The Inogen® Rove 6™ has a noise level of 39 dBA (on setting 2), while the Inogen One G4® has a noise level of 40dBA (on setting 2) which is the same noise level as a quiet library.

1260ml The Inogen One 5 System offers 6 flow settings and delivers up to 1260ml or medical grade oxygen per minute in one of our quietest, smallest and lightest portable oxygen concentrators.

Patients may have morning headaches, dry mouth or nasal irritations from the mask or nasal cannula. Frequent use of the mask or nasal cannula can also lead to skin irritations from the mask contact.

Most people must use supplemental oxygen for at least 15 hours every day. Some people need to use it 24 hours a day. A healthcare provider will direct you on how often to use it and what your output setting should be. If you have a short-term condition, you may only need an oxygen concentrator until you recover.
