Inogen One G4 Portable Oxygen Concentrator Review

Reliable portable oxygen therapy is an important factor in the treatment of respiratory disease. Patients who enjoy active lifestyles - such as hiking, traveling, or just running a lot of errands – need an oxygen concentrator that is rugged, reliable and compact. The Inogen One G4 Portable Oxygen Concentrator is the perfect choice. The sleek design combined with the simple-to-use interface and custom battery configuration makes this an ideal choice for any user. Let’s take a look at the features of the Inogen One G4 below.

Benefits of Using Inogen One G4 Portable Oxygen Concentrator

Portable oxygen therapy delivers a number of benefits, and with the Inogen One G4 concentrator, these benefits are even greater. For example, traditional portable oxygen concentrators are lightweight, compact units that are easily transportable no matter the lifestyle. The Inogen One G4 concentrator is one of the lightest units on the market, weighing in at only 2.8lbs. It is also compact, measuring approximately 6” x 3” x 7”.

Another benefit of the Inogen One G4 portable oxygen concentrator is the battery life. On its lowest pulse dose setting, the G4 offers approximately 5 hours of battery life with the extended battery. Additionally, the user interface is incredibly simple, allowing users to easily track their oxygen therapy settings and check device status.

How Does the Inogen One G4 Portable Concentrator Compare to its Competitors?

Let’s take a look at how the Inogen One G4 portable oxygen concentrator stacks up against some of its competitors.

Inogen One G4 Design

As previously mentioned, the Inogen One G4 oxygen concentrator is the one of the lightest portable oxygen units on the market. It offers a sleek, compact design with an easy-to-use interface. Carry the device on a shoulder strap or pack it conveniently for long trips.

Maintenance

The Inogen One G4 is virtually maintenance free. Clean the intake filters weekly and replace them if damaged, discolored or wet. Wipe the exterior of the concentrator down occasionally and swap nasal cannulas as needed. 

Noise Level 

On a Pulse Dose setting of 2, the Inogen One G4 has an operating volume of approximately 40dB. That is roughly the noise level of a library. Use your concentrator wherever you need it – at home, on the go, or even in a library!  

Flow Setting

The Inogen One G4 delivers oxygen in 3 different pulse dose settings. Intelligent Breath Detection is used to deliver oxygen “pulses” during inhalation only. These settings are generally prescribed by a doctor and should not be changed before first consulting your physician.

For additional therapy accuracy, do not use oxygen tubing longer than 25 feet.

Battery Duration

There are two different battery types available to the Inogen One G4 concentrator. The extended life, 16 cell battery is perfect for road trips or long flights with up to 5 hours of performance on a Pulse Dose setting of 1. 

Of course, it is always recommended to carry multiple, fully-charged batteries in the event of emergencies or unplanned power outages.

Oxygen Purity Level

Oxygen concentrators pull in room air to deliver a concentrated dose of supplemental oxygen to patients. The Inogen One G4 does this with 87-96% oxygen concentration across all settings. This is fairly standard among all concentrators.

Ease of Use

The control panel on the G4 portable oxygen concentrator consists of four large buttons and a backlit LED screen to easily check device status. Users can easily turn the device on/off, change flow settings, or mute/unmute the audible alarm.

Portability

As previously mentioned, the Inogen One G4 is one of the lightest, most compact portable oxygen units on the market, making it useful for any lifestyle.

Battery Backup

In addition to both the 8 cell and 16 cell batteries, the Inogen One G4 runs on both AC and DC power. The device can still be used if plugged in while charging, though charge times may vary depending on setting and current battery level.
