Inogen One G4 Portable Concentrator

The Inogen One G4 Portable Concentrator is one of the smallest and lightest portable oxygen concentrators that produces medical oxygen and offers a long lasting battery. This oxygen machine was designed to provide users with the highest level of independence. This innovative system rapidly detects a breath and delivers oxygen in the first 400 milliseconds. This is critical because this period is when the most gas exchange occurs in the lungs. Delivering oxygen at the start of a breath ensures that the oxygen is used more efficiently by your body. The Inogen G4 Oxgyen Concentrator can be effectively used during sleep at night, an area where many other portable oxygen concentrators fall short. With the G4, you won’t need separate oxygen systems for the day and night.

Portable oxygen concentrators like the Inogen series are the preferred choice for medical oxygen because they can be carried with one hand, require no rolling carts, and never run out or need to be refilled.
