5 Things You Should Consider When Choosing an Oxygen Concentrator

When it is time for you to choose the right oxygen concentrator for your needs, you should explore the variety of models available, the benefits they offer and any limitations they might have. In order to help make the best choice, you should also consider how, when and where you will be using your oxygen concentrator. Here are some things you should think about before choosing your oxygen concentrator.

5 Things You Should Consider When Choosing an Oxygen Concentrator

  1. Where do you live?

    Where you live has a surprising effect on your oxygen needs, so consider your location, and locations to which you frequently travel, when choosing your oxygen concentrator. People living in drier climates will require more oxygen than those living in a humid climate, which is easier on the lungs. Unsurprisingly, patients living at a higher altitude where the air is thinner will also require more oxygen than those living at lower elevations or sea level. Talk to your health care provider about how your local climate and elevation could affect your oxygen needs in order to help you choose the right oxygen concentrator for you.

  2. What type of COPD do you have?

Each case of COPD is different, and the severity of your case, along with each body’s unique needs, will play a significant part in the kind of oxygen concentrator you use. Make sure you have an updated blood-oxygen test so you and your health care provider can choose the right oxygen flow rate for you. Your oxygen flow rate needs, and the times at which you will need oxygen therapy, will help you choose the right oxygen concentrator for your oxygen treatment.

  1. What is your typical activity level?

    When you are researching oxygen concentrators, it is important to take your activity level into consideration. If you get a lot of physical activity or you have an active social life, size and weight will play a big role in your oxygen concentrator selection. You will likely choose a portable oxygen concentrator (POC), but the more active you are, the more important the convenience of a smaller size and a lighter weight concentrator will become for you. Conversely, if you are unable to be physically active and must remain at home the majority of the time, you will be less concerned with the size and weight of your oxygen concentrator and may want to consider a stationary concentrator instead.

  2. Do you travel?

    If you travel frequently, or if you intend to take a lengthy trip in the near future, you will want a portable oxygen concentrator that can make the trip with you and make travel easier and worry-free. The more you travel, the less weight you will want to carry with you, so consider what you are willing to carry on an airplane, on a train or while you are walking around. Additionally, traveling requires enough battery to last the trip—particularly if you are on full time oxygen or need a high flow rate for a significant amount of time. As such, you should take battery life into account, along with your flow rate and frequency of use to ensure that you are well equipped to receive the oxygen you need. Talk to your doctor about how travel could affect your oxygen needs.

  3. How long do you need to use oxygen?

    The amount of time you will need oxygen treatment per day, as well as the length of time that you will need oxygen therapy, will be determined by your particular needs and the severity of your COPD. While some people only need short-term oxygen treatment because of a COPD flare-up or an upper respiratory infection, others in the later stages of COPD need full-time oxygen therapy for the rest of their lives. Your doctor will help you understand how long you will require oxygen therapy, as well as how many hours of oxygen treatment you will need per day. Once you know the frequency with which you will be using your oxygen concentrator, it will be easier to choose among the available options.


Why You Might Choose Different Oxygen Concentrators

Before choosing your oxygen concentrator, carefully consider the five questions above, and talk with your doctor about the length, frequency and flow rate of your required oxygen therapy. Once you determine what you need from your oxygen concentrator, you can choose from the available options. Here are the options offered by Inogen, as well as why you might choose each of them.  


Inogen One G4 System

The Inogen One G4 portable oxygen concentrator system is the smallest Inogen One System available. At 7.2 inches tall, 5.91 inches long and 2.68 inches wide and weighing less than 3 pounds, the Inogen One G4 is slightly bigger than a large coffee mug, making it extremely easy to take with you wherever you go. It is also very quiet—40dBA at setting 2—allowing you to carry on regular conversations without issue. This is also the most technologically advanced Inogen One System with a Bluetooth System allowing users access to the Inogen Connect App to monitor their oxygen use and their G4 System through any supported device. For users who travel frequently or want to maintain an active lifestyle, the small size and lighter weight of the Inogen One G4 make it easy to take your oxygen therapy with you. Offering three flow settings, this system is clinically validated for use 24 hours a day, 7 days a week, using Inogen’s proprietary Intelligent Delivery Technology® to deliver oxygen effectively and efficiently whether you are sleeping, at rest or exerting yourself. The G4 System also meets FAA requirements, making it both safe and convenient for air travel. The battery life lasts up to five hours with the double battery, but if you will be traveling for long periods, consider an external battery charger or one of the Freedom Packages, which offer additional batteries and a Lifetime Warranty for peace of mind. For users with active social lives, who travel or who want to be able to maintain an active lifestyle, the Inogen One G4 System is the ideal choice.


Inogen One G3 System

The Inogen One G3 System is also small and quiet, though this portable oxygen concentrator is a little larger than the G4. The Inogen One G3 is 8.25 inches tall, 8.75 inches long and 2 inches wide, and weighs 4.8 pounds, but for the slightly larger size and weight, you get five flow settings and a battery life of up to 10 hours with the double battery. The Inogen G3 is clinically validated for use 24 hours a day, 7 days a week and incorporates Inogen’s Intelligent Delivery Technology® to help provide continuous, efficient oxygen whether you are exerting yourself, at rest or asleep. It meets FAA requirements and can provide you with the oxygen you need anytime, anywhere. If you are someone who requires additional flow settings or will be traveling for long periods and need a longer battery life, yet still want the freedom and convenience of being able to easily bring your oxygen concentrator with you, the Inogen One G3 is the right choice for you.


Inogen At Home

The Inogen At Home is our stationary system, ideal for anyone who only receives oxygen treatment at home. This system provides 5 liters per minute of continuous flow oxygen, but remains extremely quiet while in use. The Inogen At Home is also extremely energy efficient, using only 100-watts on flow setting 2. Despite the fact that it is a stationary system, this oxygen concentrator is still quite small. At 16.5 inches tall, 13 inches wide and 7 inches deep, it weighs just 18 pounds, allowing it to be moved from room to room as needed. The Inogen At Home is ideal for any user who can maintain their oxygen therapy at home.
