POC Inogen G5 oxygen machine hours of usage


Inogen’s patented Intelligent Delivery Technology ensures your oxygen therapy is delivered efficiently and effectively in all modes of use. In fact, the Inogen One’s oxygen delivery systems are clinically proven to provide the necessary oxygen for most ambulatory patients during all phases of daily activity and during sleep. Recommended for 24/7/365 use.

Intelligent Oxygen delivery technology at night

  • Unlike other oxygen systems, 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.


Inogen is the pioneer in portable oxygen technology offering a more powerful and efficient O2 therapy on-the-go than its predecessor models from the G series.
