Inogen Gen 3 vs. Inogen Gen 4 Concentrator Comparison

Description: Inogen One G3 vs. Inogen One G4 Concentrator Comparison

Selecting a suitable oxygen concentrator is a lot of hassles especially if you are not well-informed. There are multiple oxygen concentrators currently in the market. So, navigating the market and selecting the right choice can be nerve-wracking.

The most popular portable oxygen concentrator in the market currently is from Inogen’s brand. Inogen has a well-established reputation when it comes to designing small, lightweight, and trustworthy oxygen concentrators. The company provides users with a few types of oxygen concentrators. But in this article, we want to look extensively at the features of Inogen Gen 3 vs. Inogen Gen 4. These two oxygen concentrators from this premium brand are good products. However, they differ slightly from each other and your final choice will depend on your specific oxygen needs.

To help you decide which among these two oxygen concentrators suit your needs, we are going to make a side by side comparison of these two products in this section of the article. We are going to base our comparison on the following factors:

Inogen Gen 3 vs Inogen Gen 4 comparison: Factors to consider

1. Inogen Gen 3 vs. Inogen Gen 4 Oxygen Flow Settings

While the Inogen Gen 3 and Gen 4 have many similar features, they have unique features that set them apart from each other. Both Inogen G3 and G4 come in oxygen pulse delivery mode. Delivering oxygen through this mode is beneficial because it preserves oxygen. Besides, it adjusts the delivery setting depending on what you need.

Whereas Inogen Gen 3 delivers pulse settings that range from 1 to 5, the Gen 4 delivers oxygen with pulse settings of 1 to 3.Therefore, while the Gen 3 deliver a maximum of 5 liters every minute, the Gen 4 merely delivers a maximum of 3 liters of oxygen every minute. Multiple pulse delivery settings are beneficial as it will adjust to different activities level and delivers a suitable amount of oxygen at any given time like when you are active and you are resting or sleeping.

The two portable oxygen therapy systems use pulse delivery. This means that any time the machine detects a breath, it sends out a bolus or outburst of oxygen each time a breath is detected. Because the design only allows the system to deliver oxygen when the breath is detected, it is unlike a few oxygen concentrators that deliver oxygen non-stop. This feature also impacted on the size and makes these two Oxygen therapy systems from Inogen small-sized and lightweight.

The Inogen Gen 3 and its sister Unit Inogen Gen 4 integrates Inogen’s Intelligent Delivery Technology. This breath intelligent detection technology is quick and exceptional sensitivity. This ensures that it only delivers oxygen to users at the start of every breath cycle. It aswell increases the oxygen delivery rate when breath rate decreases by activating a bigger bolus size depending on a fixed volume rate of delivery.

Equally, when the machine detects a faster breathing rate, it activates a smaller bolus size which may result in out-breathing the unit’s capacity. If you notice that you constantly experience short of breath when you utilize an Inogen, it could be as a result of a fast breathing rate. You may need to get a different oxygen concentrator model to fulfill your requirements.

One greater feature of Inogen oxygen therapies is the auto pulse mode. The majority of oxygen therapy patients commonly breathe through their mouths and anytime they breathe through their mouths, the unit detects it and does not deliver oxygen. When the system does not detect oxygen, it will make an audible alert sound and if it stills fails to detect breath, it will enter into an auto pulse mode and this time it delivers a bolus of oxygen intermittently till when it detects a breath.

2. Weight and Size

These two portable oxygen concentrators weigh less than 5 lbs. While the Inogen Gen 4 weighs less than the Inogen Gen 3 and with a weight of 2.8 lbs with a single or small battery and a weight of 3.5 lbs with the 8-cell (large) battery. The Inogen Gen 3 model weighs 4.8 lbs. with a standard –cell or small battery and weighs (5.8 lbs. with the large battery).

The two concentrators are comparatively lightweight and portable and can easily be taken while traveling. The Inogen Gen 4 is the most lightweight concentrator ever available in the market while the Inogen Gen 3 is the smallest concentrator in the market with a pulse setting of 1 to 5. The Gen 4 concentrator comes with roughly 7 inches height, 6 inches width, and roughly 3 inches depth. The Inogen Gen 3 concentrator is a bit above 8-inches tall, nearly nine inches wide, and 3 inches deep.

3. Battery Life

Both Inogen Gen 3 vs Inogen Gen 4 concentrators have two battery options; a smaller and lighter one and a larger double battery which doubles the battery time on the majority of the settings. However, while Inogen Gen 4 comes with a single battery with 4 cells and a double battery with 8 cells, the Inogen Gen 3’s single battery comes with 8 cells while its double battery comes with 16 cells.

How long you will be able to use the unit at any given time depends on whether it is using a single or double battery and the oxygen pulse setting the machine is running. Inogen Gen 3 tends to have a longer run time because it comes with a larger battery.

For Inogen Gen 3 concentrator with the 8-cell battery, the battery life is 1.7 hours when the setting is on 5 and the battery life will average 4.5 hours of battery life when on setting one.

For Inogen Gen 4, the system lasts only for an average of 1.2 hours when the setting is on three and when the setting is on three, it lasts for an average of 2.4 hours. Besides the battery that each of these units can in, both of these oxygen concentrators come with an AC power adapter. So, they can run constantly by plugging them into a wall outlet.

They equally come with a DC power adapter which you can plug into a supplementary power outlet in your car. This is useful as it enables you to run the machine through the battery of your car and ensure your battery is fully charged by the time you arrive at your travel destination.

4. Portability

While their stationary concentrator is heavier than Gen 3 and Gen 4 they are lighter than similar brands and can easily be transported. The Inogen gen 3 and gen 4 are correspondingly lighter. Their lightweight makes it easy to move it about. They were built for portability. Besides, their carry bag makes it easy to carry with the included shoulder strap. The two devices are less than 8.25 inches high.

Inogen provides one of the best lightweight and portable oxygen concentrators in the market. Both their concentrator, Gen 3 and Gen 4 are lightweight as they were built for portability

5. Price

It may interest you to know that Inogen sells these two concentrators at the same price point. Both units cost 2.295 dollars for the main system. Thus, price is not a differentiating factor between these two systems. Thus, when you buy the systems depending on the one you finally settle on also purchase the carry bag, the carry bags are sold separately.

Inogen has designed a pricing structure that makes it easy for buyers to purchase only what they need and not what they can afford. Although the two devices cost more than the In-home model, the extra price is to account for the additional accessories that come with the portable models. Given their price, you can select either Inogen Gen 3 and Inogen Gen 4 based on what your needs are and not based on any pricing factor.

Power Source

While the in-home system makes use of the AC power supply system that alters based on the setting used, the Inogen Gen 2 and Inogen Gen 4 make use of a battery system that can take up “Single standard eight cells Batteries” and “Double Batteries with sixteen battery cells. The double battery is two single batteries structured as one. Therefore, this makes the battery life of such cells to double. While you’d expect the life in Inogen Gen 4 to be better than the battery life of Inogen Gen 3, the reality is far from that. The double battery of Gen 3 can last for nearly 10 hours depending on the pulse setting while the double battery of Gen 4 has a life span of 5 hours.

Whether you should get a single battery or double battery depends on the length of your proposed journey and whether you want to go for a prolonged trip. If you are traveling to long distances, it is wise to have an alternative battery to swap when the current one discharges. Luckily, these Inogen mobile units also come with a DC power supply cable you can use in your car cigarette lighter or DC power supply to charge your device while on the go. With the DC cable, your car battery allows you to charge your concentrator and so this can improve the battery life. Also, the Inogen Gen 3 and the Inogen Gen 4 can equally run on the AC power supply while you are at home. Therefore, you don’t need to swap the battery when you are at home.

Airplane Travel

The Inogen Gen 3 and Gen 4 fulfill the FAA requirements for use in airplanes. The small size and long battery runtime are your preferred choice when going away through air travel. Although you may be tempted to think that the unit with a higher pulse flow setting is the best, the G4 that comes with only 3 flow settings come with extra benefits FAA compliance (for air travel) and it’s lightweight.

The major deciding factor is whether your doctor decides you require over 3 liters of oxygen for any reason like when you engage in physical exercise, in such situations, you require Gen 3 as Gen 4 won’t be suitable. However, if your doctor does not think you will need above three liters of oxygen besides in an emergency situation, the best option would be the Gen 4.

Overall, consult your doctor for advice on your oxygen needs and ensure you select the option that will fulfill your oxygen needs in different circumstances.

Extra Information

These two portable oxygen concentrators from Inogen-Gen 3 and Gen 4 are quiet operating machines, with 39 decibels for the noise level of Gen 3 and 40 decibels for the noise level of the Gen 4. The noise level is negligible and can compare to the sound of a “quiet conversation.” The Gen 3 model features a carry bag with a strap on the bag while the Gen 4 model comes with a strap built into the oxygen concentrator unit and comes with a different carry bag.

The Final Selection: Inogen Gen 3 vs. Inogen Gen 4

Overall, the Specifications of the Inogen Gen 3 and the Inogen Gen 4 are comparatively related to one another while the Gen 3 model is bigger and heavier, it gives you the chances to utilize more pulse settings than the Gen 4 model. These two oxygen concentrator models are designed for individuals with COPD when they are out-and-about or when they are at home.

You should go for the Inogen Gen 3 if your oxygen need is higher and you require oxygen concentrator with a longer battery lifespan.

Factors to consider before purchasing a used oxygen concentrator

1. Choosing a suitable device

With the multiple brands of equipment and models available in the market, it can be hard for you to select suitable equipment. You will need to get a professional provider with wide selections of different models and brands to give you multiple options.

The provider must also be knowledgeable to advise you on the best suitable product for your needs. Most people end up choosing an option which would hardly meet their medical oxygen needs. Purchasing an unsuitable unit can put your health in danger.

Returning back the unit can equally be a lot of hassles and a bit costly. You may need to pay more than 500 dollars to follow the small print in return policies. Your best solution is to work with a recognized dealer who represents more than one brand of the oxygen concentrator. This way you enjoy peace of mind that you are making the best choice for your health and accordance with your day to day lifestyle.

2. The dealer you purchase from is significant

Buying from a recognized dealer is worthwhile. You never know, you could require additional information after purchasing the unit. So, buying from a reputable dealer will make life easier when you need after purchase support like further usage advice, technical support, extra equipment or if you want to sell your unit back.

In this type of situation using a dealer with technical knowledge can be invaluable. Your machine could malfunction for instance. It could be difficult to get good technical support when you are already facing a problem. So, it is better to speak with the support department before you make your purchase to ensure that you will get after purchase help should you need one.

Also worth noting, the manufacturers in this industry are unique in that all repair work must go through the retailer where you purchased your unit. Good support can be invaluable.

3. Be conscious of your data security:

It should really worry you immensely to hand over your private information, financial information and medical details to someone you don’t know. Any data breach can lead to very expensive consequences.

Having said these, consider the tips below when purchasing used oxygen concentrator to ensure you stay safe especially if you want to buy online.

Factors to consider when buying Used Oxygen Concentrators Online

While you can get a good deal from reputable online sources, you should also be conscious of the potential cheating from unscrupulous elements. While purchasing things online, the product may not reflect the true nature or quality of the product. If you end up making a wrong purchase, you will be in for a costly mistake. In the end, you could be spending so much more money than you would have used to purchase a new and unused model.

Follow the steps below to ensure you purchase rightly:

1. Check to ensure that you purchase from a Real Company

The best way to ensure that the company you want to purchase from is legitimate and real is if they are accredited by an external body. Given that oxygen therapy is a prescription medical treatment frequently given to the elderly, the government endorsed nine accrediting bodies to monitor and regulate care.

The nine approved accrediting bodies include the following:

So, check that the company is accredited with any of these nine bodies. Besides these nine bodies, no other government certified agency can check if the business you want to purchase from is truly accredited for health, safety, and business best practices.

These third-party agencies check and authenticate the business processes and practices of medical companies usually by conducting an audit for a full day. They’d normally check if the company complies with the HIPAA requirements, credit card supervision, support systems, neatness, and financial viability.

Besides ensuring that the company you want to purchase from follows acceptable business practices, you want to also ensure you have a backup route to channel your complaints if things should go contrary to expectations.

So, we propose that you verify beforehand from the company you want to purchase from if they are accredited, which accrediting body and how you can find their company from the website of the accrediting body.

2. Check the company’s rating on the Better Business Bureau’s Website

Regrettably, businesses currently buy better business bureau ratings. Some websites occasionally post a picture of BBB ratings without any actual association with the BBB. So, be careful! Don’t jump in to purchase from a site because it displays an A+ rating with the BBB. You should always click through the BBB website or give the BBB a call to find out if the rating the company displays on its website is authentic or not.

When you visit the company page read the issues they have had with customers and how they handled it in the past. Every company will experience issues with customers from time to time. The concentration should be on how the company manages its customer’s concerns. Examine particularly, the company’s return policies and issues with the company’s product.

If you couldn’t find a company’s official report on the better bureau website, there may be an issue behind this. It should be a cause of concern. So be careful about who you purchase your products.

We recommend you read the issues that have come up. Every company will have “issues,” and what you should be concerned about it how it addresses customer concerns. Pay particular attention to people with returns or product issues. If a retailer does not have an “official” history with the BBB, beware because there is likely a reason.

3. Confirm the physical Address of the company

Although, we don’t recommend purchasing from non-accredited companies if you really have to, ensure they have a physical address you can visit if things go wrong. A lot of companies operate with virtual addresses and if you want to ensure that the company you intend to use is authentic try to trace it to a physical address. You can verify if the address they put on their site exists through Google map.

Some companies pay a minimal sum to appear they are located in a specific office building and utilize such an address when operating only. So be conscious of a business with an address that many other businesses use. You need to do this because you don’t want only purchase your device but also the company would be there to provide you support if anything goes wrong.

4. Check that the company is true to its advertisement policies

When a company utilizes questionable advertisement techniques, the implication is that they are commissioned agents who engage in the aggressive pre-sale campaign. Most likely these advertising agencies would not be there when you would require support.

5. Purchasing from non-accredited companies could constitute some health issues

Medical equipment can harbor harmful microorganisms if not well maintained. Because you are purchasing a used oxygen concentrator, you want to ensure that they are in perfect working condition and hygienic. You need some special cleaning chemicals and properly defined procedures to keep these devices suitably clean. When you use a company that is not accredited, you will not know, whether or not, the units are cleaned properly following the right procedures.

Moreover, you can get a unit that seems to be functioning but fails to supply medical grade oxygen. Oxygen purification requires specialized and standardized equipment. Even when you see such words like “certified pre-owned concentrator” or “our technicians inspect,” you can really be sure on the quality of the product you want to purchase except the company’s is accredited and you could trace their avowal to BBB site.

7. Examine the Company’s Return Policies Critically

There ought to be functional return policies to keep you and even the business protected. Tell the company about your situation. If the company is reputable, they will work with you to make sure they meet your needs. Carefully read the company’s return policy. The majority of non-reputable businesses out there would hardly let you return the product once you’ve opened the box.

6. Oxygen Concentrators frequently requires a prescription

This is vital and beneficial to customers because, without prescription, majorities of customers struggle to figure out the best suitable concentrator for their oxygen needs. Also, it is essential to have your RX on file in case you experience any issue with the unit when you travel. Although, this not without hassles, it is essential to do things as stipulated by law to keep both buyers and businesses safe.

Companies that do not ask you for prescriptions must be non-accredited. They could be consciously circumventing the law and compromising your safety. When a dealer promises to obtain your RX, ensure you’re entrusting your personal health information into the hands of a reputable accredited agency and make sure you have them send you a copy.

9. State Accreditation/Licensing for supplementary Oxygen therapy

Rules for being accredited for selling oxygen concentrators vary from state to state. Some states are stricter with their rules. Florida, for instance, has a very strict policy for being licensed to sell oxygen. It includes fulfilling such conditions as a brick and mortar office location, financial viability, and efficient business practices. Reputable vendors are licensed.

This is very beneficial for customers and ensures they are protected and the company won’t be taking advantage of them. If you live in Florida, follow the link to check if the company you want to purchase from is licensed by the state to sell oxygen. For prospective buyers from other states, try to get similar information from your state before you purchase from a company.

Final conclusion purchasing Used Oxygen Concentrators

While we recommend purchasing used oxygen concentrators if you want to save money, you need to be careful to select from a suitable company. You may end up buying what doesn’t even worth the low price you paid for it.

Deciding whether to buy a used concentrator or new one, bear in mind that no one answer to the question will work in all situations for all people. Therefore, try to do your research to get a concentrator that meets your oxygen needs, the one that is suitable for your lifestyle and budget now or old.

What is the benefit of using Oxygen supplements?

The oxygen supplements are commonly recommended for individuals who have lack sufficient supply of oxygen. When the systems start to improve after using oxygen supplement for a while, the symptoms of insufficient oxygen starts to improve and your body will start to get the needed therapy.

This will make you experience a burst of physical energy. Also, because oxygen affects the function of brain cells, you will probably observe a general boost on your whole brain function and health. The advantages of using an oxygen supplement will become immediately apparent once you start to use your concentrator.

While wearing a cannula is not what you want in an ideal situation, advanced technology now makes very soft cannula tubing possible. There are equally very subtle cannula laden eyeglasses. The therapy will help you to regain your viability so you can get as active as you use to be which would improve your overall health.

Also, as soon as you start to experience the personal freedom of returning to work, making trips and visiting your loved ones, you’d appreciate what the concentrator and cannula are doing for you and will find it easier to adapt to using the machine.

Does Oxygen Supplement have any side-effect?

You may be tempted to think that you can live comfortably without oxygen supplement, however, using one greatly boosts the quality of life. An erroneous conception is that using oxygen supplements will make you more dependent on the therapy and eventually weaken your natural capacity to process oxygen.

On the contrary, oxygen therapy boosts your body’s natural systems and makes them function more effectively. It will minimize excessive strain, and increase your general health.

A potential side-effect of oxygen therapy is occasional nose dryness or sinuses. You may need to try out various types of cannulas or skin gels to get a comfortable and suitable arrangement. Thankfully, with the present-day modernizations in cannula technology, you can easily get a softer, properly cushioned, and a more comfy fit.

The process of operation of Oxygen Concentrators

Irrespective of size, the mode of operation of all oxygen concentrators is the same. First, the concentrator sucks up the air around it via the filter and eliminates air particles and atmospheric air containing a mixture of gases. After filtering the air, the filtered air travels through a molecular sieve chamber which separates the oxygen from the nitrogen and other atmospheric gases. The machine will then eliminate the other gases and retain only pure oxygen molecules.

The pure oxygen produced is then made into concentrates so it meets the grade of medical oxygen. The medical-grade oxygen produced is instantly supplied to the patient through a nasal cannula. During operational periods, you can perceive a distinguishing intake and elimination cycle.

Stationary Vs. Portable Oxygen Concentrators

Once between the stationary (“in-home”) oxygen concentrator and portable oxygen concentrator is their size and ease of moving them about. The stationery or home oxygen concentrators are basically larger in size and are designed to be utilized at home while the portable oxygen concentrators are smaller, lighter and are designed for use when you are on the go.

They are just as their name implies portable units. Their mode of operation is similar to that of the home oxygen concentrators, the only, however, is that they run on battery power and on DC power sources like the cigarette lighter built into cars. They are basically structured to substitute oxygen tanks and offer patients extra flexibility band mobility.

The stationary oxygen concentrators come in stationary settings that are easy to understand and manipulate. Besides pressing the power button, the main alteration that you need to do on the majority of them is the flow tubing with a dial on the base.

This knob alters the liter flow for every minute. If you are using a recent version of stationary oxygen concentrators, you’ll alter the settings through “+” and “-” knobs. Use the “+” sign settings to increase the airflow and use the “-” sign setting to reduce the airflow.

Patients suffering from Sleep apnea are commonly placed on oxygen supplementation therapy. Patients with a CPAP or BiPAP and are using oxygen supplement links up their sleep apnea machine to the home oxygen concentrator for a continuous supply of oxygen.

Portable Oxygen Concentrators

The main difference between the home oxygen concentrator and the portable oxygen concentrator as we mentioned above is in ease of transportation. The mode of operation of these two types of oxygen concentrators is mainly the same. However, the possibility to run a portable concentrator through extra sources of power and give patients more flexibility. The patients are now no longer concerned about exhausting the oxygen in their tank. Their major concern with these portable units is to ensure that they can easily access a power source to recharge their units when necessary.

Pulse vs. Continuous Flow

The portable oxygen concentrator functions through two different methods. While some work through pulse dose, others function through a combination of pulse dose and continuous flow. Pulse dose is a form of supplementary oxygen delivery that replicates the methods that were previously used for the delivery of oxygen stored in a supply tank.

Pulse dosing implies that rather than engage in continuous delivery of oxygen into the nostril of the patient, the oxygen is supplied to the patient’s nostrils in short spurts referred to as a bolus anytime the patient breathes in. Pulse dosing in a portable oxygen concentrator makes it possible for the device to utilize a less heavy and smaller compressor because the machine does require such hard work. It equally assists the machine to lengthen its battery life for an equivalent reason.

The second method of delivery utilized by oxygen concentrators is where continuous flow is merged with pulse flow. These machines can change between pulse dose and continuous flow once you press the knob. This system of delivery helps patients and offers them more flexibility of changing to pulse delivery when they want to prolong their battery and return back to the continuous flow when the unit is plugged into an AC power supply to be utilized especially while sleeping at night.

A lot of research has been conducted to verify the benefit that comes from using pulse and continuous flow concentrators vs. only pulse dose. We suggest that you always seek your doctor’s advice to know which delivery method is suitable for your medical condition and lifestyle. However, the general recommendation from doctors is to use continuous flow if you need supplemental oxygen therapy at night.

Settings of the oxygen concentrators

While continuous flow systems are easy to set. All you need to do is choose the number of liters per minute of oxygen, pulse dose oxygen concentrators comes with a more complex setting mechanism. As soon as you get more accustomed to using your device, it will become as easy just like using your television remote. However, at first, you need some learning curve to get used to it.

Using a Double-delivery Mode System

A few portable oxygen concentrators come in settings which let you select either continuous flow or pulse flow on the same unit. The units that come in both pulse and continuous flow are larger and heavier than those that deliver only through the pulse mode.

This is because the double systems need a larger pump/motor assemblage. They come with additional electronic systems and their molecular sieves are larger. They commonly come with a weight below 20 lbs just like a carry-on airline bag. They equally feature carriage wheels and one handle that you can retract when not in use.

The most common practice between patients is to use the pulse dose during the day and return to continuous does at night. This usage model is recommended because, at night, you experience shallower breaths and some health personnel worry that the activation system on a pulse dose oxygen concentrator may fail to set in at night due to shallow breaths. If you want to test whether or not your style of sleep requires a continuous oxygen flow, you should find out from your doctor if you can start using continuous flow at night by going through an overnight oximetry test.

Weight

Portable oxygen concentrators are comparatively less heavy than an in-home concentrator. The lightest machines can weigh as small as 2 lbs while the more powerful machines would weigh roughly 15 to 20 lbs. The large difference in the weight of these two types of systems is mainly as a result of their functionality and usage. While the smaller units deliver oxygen only through pulse and come with fewer settings. Machines that weigh more than 8 lbs commonly feature a wheeling system. The majority of patients find it difficult to know the difference between an 8 lbs machine and a 15 lbs machine when they wheel it with their travel carts.

Battery Life

The lifespan of batteries that come with these machines differ greatly depending on the machine, batteries they use and their settings. Generally the harder the task the machine does, the shorter the life span of the battery. For example, machines that deliver through continuous flow does extra work and consumes more battery than machines that deliver through the pulse.

Similarly, a machine does more work with the high setting than it does when on a lower setting. It is similar to the gas mileage which consumes more gas when you move faster than when you drive slowly. Therefore, a portable oxygen concentrator will prolong its battery life when it delivers through a pulse dosage and on a lower setting and then it delivers through a continuous flow at a higher setting the battery lifespan tends to be small.

Many portable oxygen concentrators currently make use of lithium-ion batteries. This is related to a lot of computer batteries that are powerful and come with extended lifespan. Nevertheless, the quality of the battery will get less after using it for a while. The majority of producers of battery recommend a maximum recharge of the lithium-ion battery of 300 times without any substantial degradation. The battery life can be extended through periodical cycling and avoidance of excessive temperature usage.

The Portable Oxygen Concentrators Revolution

A portable oxygen concentrator (POC) technology is a long-awaited solution. The majority of people placed under oxygen therapy before now can hardly move about outside their home without compromising their health and safety. The POC then is a welcome solution to patients on oxygen therapy who desire additional mobility outside their home. Now, with this new innovation, these patients no longer get confined in their homes or have to wheel a heavy cart of oxygen flammable tanks about on a wheeled cart.

These portable oxygen concentrators come with the ability to generate pure oxygen concentrate from the air surrounding the individual and this is very comforting as it has liberated individuals with COPD and other physical health conditions. They can now be able to work again and carry out their regular day to day’s activities. They can equally become as social as they want to be, fly airplanes and engage in different types of exercise. The advantages of these mobile oxygen concentrators cannot be overemphasized.
