Inogen One G3 Portable Oxygen Concentrator Overview

The Inogen One G3 was designed with independence in mind. This portable oxygen concentrator weighs 5lbs making it ideal for travel of any kind. For even more portability, the Inogen One G3 comes with a carrying bag or can be paired with the optional backpack accessory.

Like most portable oxygen concentrators, the G3 provides oxygen delivery through what is known as pulse dose. This means that as the user inhales, the device detects that breath and delivers the set dose of oxygen. As the user exhales, no oxygen is delivered. This Inogen One device offers 5 pulse dose settings, which can easily be changed using the device’s flow control buttons. Consult your physician prior to changing your oxygen delivery settings.

It is currently one of the smallest, lightest portable concentrators on the market which produces a setting of 5. For times you need additional battery life, an upgrade to a 16 cell battery can increase usage to 9 hours with a weight increase of less than 1 lb.

The Inogen One G3 is smaller, lighter, and more efficient than its predecessor, the Inogen One G2. At only 5 lbs. you can hold it with one hand without much trouble but comes equipped with a sleek, carry case with a handle that can be worn over your shoulder for even more portability.
The 8 cell or upgraded 16 cell batteries are recharged quickly approximately 4 hours for the 8 cells and 6 hours for the 16 cell battery. To conserve energy and time between charges, the Inogen One G3 has five settings of breath detecting pulse oxygen flow.
Portable oxygen concentrators filter room air to provide individuals with a concentrated dose of supplemental oxygen. No more wheeling around oxygen tanks or having to worry about getting them refilled. Simply turn on your device and breathe.

Inogen One G3 Portable Oxygen Concentrator - Features

Battery Life

At checkout, customers can customize their battery configuration with one of the two battery choices the Inogen One G3 has to offer: the 8-cell or the upgraded 16-cell. Depending on the oxygen flow settings, users will get up to 4.5 hours of battery life with the 8-cell and up to 9.5 hours of battery life with the 16-cell. View the battery duration chart below for more information.

The Inogen One G3 comes with AC and DC adapters that allow patients to not only use but also charge their device from anywhere. The LCD screen will display a battery icon with a lightning bolt or an AC plug icon to let you know the device is plugged in and charging properly. Charging time will depend on oxygen settings and whether or not the concentrator is in use while being charged. Removing the battery is simple - press down on the battery release latch and slide the battery out of the concentrator. To replace, simply slide the battery back into place until the latch clicks.

Adaptive Response

Inogen’s G3 portable oxygen concentrator features adaptive response technology that adjusts its oxygen delivery to your breathing rate. The pulse dose of oxygen reduces in size as the breathing rate increases. This ensures that oxygen is not wasted as users exhale. While sleeping or at rest, individuals inhale at a much slower rate, therefore the pulsed dose of oxygen increases to accommodate the change.
The Inogen One G3 also features an Advanced Breath Detection mode. If the G3 concentrator’s technology does not detect a breath within 60 seconds, it will begin to deliver automated oxygen pulses. Once the unit detects a breath again, it will revert back to its most recent flow setting. The alarm for this Breath Detection mode can be turned on or off using a button on the portable oxygen concentrator’s control panel.

Intelligent Delivery System

Inogen One G3 offers an intelligent oxygen delivery system capable of providing you with oxygen whether the oxygen concentrator is active or not. Unlike the traditional oxygen delivery systems, this device constantly observes your breathing and notices breathing pattern changes to ensure you are making the best of your oxygen delivery doses.

Most users require an increased dose of oxygen during their sleep and the Inogen One G3 Oxygen Concentrator ensures that you get the most appropriate doses of oxygen throughout the night.

By decreasing and increasing the pulse size the Inogen One G3 makes certain that you are receiving a constant amount of oxygen each minute as you sleep.

This Intelligent Delivery System detects shallow mouth breathing and delivers a minute volume of a pulse dose of oxygen.

Breath Detection Alert Mode

Inogen One G3 is constantly checking for breath. If 60 seconds pass by without detecting any breath it will alert the user with visual and audible signals and the device will enter into “Auto Pulse Mode.” The device will return to provide normal oxygen pulses on inhalation and exit Auto Pulse Mode once it detects a breath. To check whether the alert mode is on or not, see the mode indication area on the display. It will show a bell icon with a red light flashing and a message.
