Intelligent Delivery Technology at Night

  • Unlike other oxygen systems, such as portable tank oxygen systems, or even some other portable oxygen concentrator brands, the Inogen One is one of the only portable oxygen systems proven to work for users during rest, exertion, and sleep.
  • As your breathing rate slows, Inogen’s Intelligent Delivery Technology increases each oxygen bolus dose.
  • The G5 detects even shallow mouth breaths at night and triggers a bolus dose of oxygen based on a fixed minute volume.

So what does this mean for you? For most, oxygen systems like the Inogen One G5 can be your single solution and primary oxygen delivery supply, both day and night.

Now you can reduce or eliminate your daily need to rely on other oxygen systems and tanks and use just the G5 portable oxygen system.

The Inogen One G5 meets FAA requirements.
