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, explore the variety of models available, the benefits they offer and any limitations they might have. Also consider how, when and where you will be using your oxygen concentrator to help you make the best choice for you. 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 more extreme climates with significant changes in temperature or severe dryness or humidity may find they need to use supplemental oxygen more often. 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 G5 System

The Inogen One G5 portable oxygen concentrator system is our newest model and one of the most powerful, lightest and quietest units available for oxygen users today. The Inogen One G5 offers six flow settings—more than any other Inogen One portable oxygen model—allowing you to customize your oxygen flow to fit your needs. The G5 features up to 6.5 hours of battery life with a single battery, or up to 13 hours with a double battery, providing the versatility and freedom you want from your portable oxygen concentrator. Even with these features, the Inogen One G5 weighs only 4.7 pounds, so you can easily take your oxygen with you whether you are traveling, out and about or moving around your own home. Feel free to fly with this unit, as it meets FAA requirements, too. And, because the G5 is so quiet at just 38dBA at setting 2, you can carry on conversations or enjoy a movie without your oxygen concentrator getting in the way. The G5 System is technologically advanced, offering a Bluetooth System that allows users to access the Inogen Connect App with any supported mobile device. This app is designed to help Inogen One G5 users monitor their battery use, oxygen purity status and cannula and filter life, as well as allow users quick and easy access to troubleshooting tips, FAQs and the user manual. Users can also get timely reminders to replace parts and update software as needed. The Inogen One G5 features our proprietary Intelligent Delivery Technology®, which delivers oxygen efficiently and effectively in all modes of use. Whether you are at rest, asleep or exerting yourself, the Inogen One G5 actively responds to your changing physiology by adjusting the bolus size delivered based on your breathing rate. As such, this system is clinically validated for use 24 hours a day, 7 days a week, providing the necessary oxygen for most ambulatory patients during daily activity, exertion and sleep. To enjoy worry-free freedom, mobility and independence, consider one of our Freedom Packages, which provide additional batteries for extended travel time as well as a Lifetime Warranty for peace of mind.

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 has about the same measurements as a 1 pound bag of coffee, 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 one of 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.

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 one of the Freedom Packages so you can go about your day with ease. 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. Consider purchasing our external battery charger in order to make battery charging on the go as easy as possible.

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 3 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 4.7 hours. For extended battery life, you can get up to 10 hours of battery life with the double battery. Though this model may not offer the tech elements of the G4, it is still clinically validated for use 24 hours a day, 7 days a week and incorporates Inogen’s Intelligent Delivery Technology® to help provide efficient oxygen delivery, whether you are exerting yourself, at rest or asleep. It meets FAA requirements and can provide you with the oxygen you need anytime, anywhere.

Additionally, 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.
