Inogen One G4 Portable Oxygen Concentrator w/ 4-Cell Battery

Inogen One G4 Portable Oxygen Concentrator w/ Single Battery

The Inogen One G4 Portable Oxygen Concentrator is the smallest portable oxygen machine from the popular brand, Inogen. The G4 Oxygen Concentrator is able to provide you with oxygen from an incredibly quiet & small package. With oxygen flow settings from 1-3, the Inogen One G4 is capable of increasing your independence & freedom day & night.

The Inogen One G4 Oxygen Concentrator features Inogen's Intelligent Delivery Technology, which is what sets it apart from competitors. The Inogen One portable oxygen system ensures that oxygen is delivered within the first 400 milliseconds of breathing in, which is when oxygen has the most effect on lung gas exchange. The Inogen One G4 utilizes innovative triggering sensitivity to quickly detect a breath and deliver oxygen within this critical period. Less sensitive oxygen concentrators may create lags in the onset of the bolus, resulting in portions of the delivered bolus arriving too late, which has less effect on lung gas exchange.

Inogen One G4's Intelligent Delivery Technology also accurately detects your breathing rate and adjusts the oxygen level provided accordingly. If you’re exercising or physically active, the unit will provide smaller, quick bursts to provide you with the right amount of oxygen. However, while resting or sleeping, the system provides slower & larger amounts of oxygen to correspond with your decreased rate of breathing. This means the G4 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 to use any other oxygen system for your respiratory care needs, whether it be during day or night.
