Presenting the smallest versatile oxygen concentrator from the most prominent brand, Inogen. The Inogen One G4 is equipped for giving oxygen conveyance in a mind boggling tiny bundle. With stream settings from 1-3, the Inogen One G4 is intended to give you freedom day in and day out. It can be charged at home or while out.

The Inogen One G4 offers three oxygen stream settings. It additionally incorporates Inogen's Intelligent Delivery Technology, which separates it from the pack. This creative framework quickly identifies a breath and provides oxygen in the initial 400 milliseconds. This is important since this period is the point at which the most gas trade happens in the lungs. Conveying oxygen toward the beginning of a breath guarantees that the oxygen is utilized all the more efficiently by your body.

At just 40 decibels, the G4 delivers less commotion than a typical indoor discussion. This means you won't bother others when you utilize your oxygen concentrator and will feel more considerate in social settings. It's likewise awesome in calm situations when you need to be unobtrusive.

Moreover, Intelligent Delivery precisely identifies your breathing rate and optimizes the oxygen needed. If you’re in motion or physically active, the unit will provide smaller, quick bursts of oxygen to satisfy your oxygen requirements. During rest or sleep, the system provides larger oxygen boluses more slowly to coincide with your reduced rate of respiration. This means the G4 can be used during sleep at night, an area where many other portable oxygen concentrators miss the mark. With the G4, you won’t need a separate oxygen system for the night.

The Inogen One G4 comes with a 3 year guarantee covering the concentrator. There's additionally a 1 year guarantee that covers the sieve beds and accessories, so your entire system is protected. The starter bundle accompanies the Inogen G4 unit, single battery, AC control supply, DC control link, carrying bag, cannula, and manual. Please inquire about our Inogen G4 packages if you need additional batteries or accessories.
