Inogen Oxygen Concentrator Review – Forbes Health - Forbes
Unlike traditional compressed gas cylinders (tanks filled with oxygen), oxygen concentrators provide a safe source of oxygen-enriched air using room air, which is a mixture of 21% oxygen and 78% nitrogen. An oxygen concentrator draws room air into a cylinder that filters dust, bacteria and other air particles and absorbs nitrogen, which results in concentrated oxygen (90% or higher).
There are two types of oxygen concentrators: portable and stationary. Portable models typically use pulse mode delivery in which oxygen is delivered when the user begins to take a breath. Meanwhile, stationary models feature a continuous flow of oxygen.
Inogen currently offers three portable oxygen concentrator products—the Inogen One G3, G4 and G5—and one stationary model called Inogen at Home. Below is a summary of their key features.
Customization Options and Special Features
Splurge on the double battery for the Inogen One models if you want more flexibility with your time away from home. A double battery can keep an Inogen portable oxygen concentrator running throughout the duration of a baseball game, according to the company.
Apps and Accessories
The Inogen One G3, G4 and G5 portable oxygen concentrator models include a battery, AC/DC power cables, a carry (shoulder) strap and a protective bag for the device. The devices require a nasal cannula to deliver oxygen. Your health insurance benefits may include a free supply of nasal cannulas, so check your policy to make sure.
A carry backpack and cart are also available for the portable models.
An external battery charger is available as well, which allows you to charge multiple single and double batteries at once.
