Oxygen Concentrators Explained

Oxygen Concentrators ExplainedAn oxygen concentrator or an oxygen generator is used when a patient requires oxygen therapy. Compared to other oxygen supplies such as tanks, an oxygen concentrator is safer, more affordable and more convenient. Portable oxygen concentrators are also available which are even more convenient than the standard devices.


An oxygen concentrator is based on the principle that when nitrogen is exposed to zeolite materials, it sticks to them if the pressure is high. Zeolite is porous and adsorbs nitrogen in huge quantities. However, if the pressure is decreased, the nitrogen gas is released back into the air.

There are generally two cylinders in an oxygen machine and both of them contain zeolite pellets. These are subjected to compressed natural air. The zeolite adsorbs almost all of the nitrogen present in air, and the output from the cylinder is nearly pure oxygen gas.

After just a passage of a few seconds, zeolite saturates and so the compressed air is transmitted to the second zeolite cylinder. At the same time, the pressure in the first cylinder is reduced so that the nitrogen can escape. When zeolite in the second cylinder saturates, the first cylinder is again used to supply oxygen, and the pressure in the other cylinder is reduced. This process then continues repeatedly and an uninterrupted supply of oxygen is delivered to the patient.


The main components of an oxygen machine other than the zeolite beds are given below.

  • Air Filter: Prevents large particles in the air from entering into the system
  • Compressor: Takes up natural air from the environment, compresses it and transmits it to the zeolite cylinders
  • Oxygen Tank: Collects pure oxygen and delivers it to the patient
  • Valves: Adjust the flow at which oxygen is delivered to a patient

Inogen Portable Oxygen Concentrators

A portable oxygen concentrator is used when patients need an increased level of oxygen than what is present in the air. This is very similar to a home oxygen concentrator, which is often huge and bulky, and is difficult to carry around. On the other hand, portable oxygen concentrators are small in size which makes them more convenient for traveling.

There are many portable oxygen concentrators available, but Inogen is probably the best of them. The main reason behind this is that Inogen’s battery life is much more than what other manufacturers offer.


There are many benefits of preferring Inogen over other oxygen concentrators. Some of them are given below.

  • Portable: The name does make this advantage obvious, but Inogen devices are even smaller than other portable oxygen concentrators. They do not comprise of any oxygen tanks so the patient need not worry about his tank running short of gas whenever he is not at home.
  • Simple to Use: Inogen products can be easily used by anyone from kids to elderly people. There is no need to fill or refill tanks, and the devices operate with just a few button presses.
  • Performance: Inogen is known for never compromising on performance and quality, and the same is demonstrated in their products. Despite the small size, each product is capable of producing a large amount of oxygen per pound.
  • Battery Life: This has already been discussed, but needs mentioning again. Inogen uses lithium batteries that can last up to 16 hours, whereas other portable oxygen concentrators last only two to three hours. When the battery has been discharged, they can easily be charged through any electrical outlet including the cigarette lighters in cars.

Inogen portable oxygen is available in two models: Inogen One G2 and Inogen One G3. The main features of the two products are pretty much the same. The only significant difference is that Inogen One g3 is smaller than Inogen One g2. In fact, it is almost half the size.



Oxygen Concentrator Buying Guide

Many patients require oxygen constantly. This becomes a problem if the patients need to travel, because not all oxygen equipment can travel with them. A solution to this is to get an oxygen concentrator that is portable. Today, a variety of different oxygen concentrators are available in the market making it difficult to decide which one would be most suitable. When deciding, consider the characteristics and benefits offered by the product.

Battery Life

If you are traveling over a longer distance, you might prefer a portable oxygen concentrator that has an elongated battery life. However, such oxygen machines are heavier and may not be suitable for traveling. A small concentrator, which can be connected to an AC outlet on a wall or a DC outlet of a vehicle, will be appropriate for such situations. For precautionary measures, take one or two batteries along with you.


Smaller oxygen machines usually have a lower output capacity, but are the best option for long distance travel, such as on a flight or a cruise. All portable oxygen concentrators are FAA approved and can be carried while traveling however, only the Sequal Eclipse 3 is suitable if you are traveling by cruise. To decide which oxygen machine is most suitable, evaluate your oxygen or liter flow requirements. The capacity can vary from one liter per minute to three liters per minute.

Pulse or Continuous Flow

The kind of machine you purchase also depends on how you intake the oxygen. This is the most vital feature that should be considered when buying oxygen therapy devices. Pulse machines deliver oxygen to you in the form of puffs while continuous machines provide a continuous oxygen supply.


This is also an important feature that should be taken into account when purchasing an oxygen machine. If you are not traveling, you can buy a large home oxygen concentrator. It will have a greater supply and, as you are not traveling, may be quite appropriate for you. However, while traveling you should have a small concentrator that is easy to carry and move around.

Refilling Oxygen Tanks

Oxygen tanks are equipment that store oxygen as gas under high pressure or in liquefied form. It is mostly used by patients who require a constant supply of oxygen. They can keep an oxygen tank at their home and refill oxygen tanks directly from the concentrator tank in their home.

Medical oxygen tanks are even available in hospitals and contain a greater supply of oxygen as it is constantly needed for patients that are under treatment. These tanks are easy to use and quite affordable.


The iFill is an oxygen refilling station that does not require a concentrator to refill oxygen cylinders. Instead, fills itself with purified oxygen that it takes in from the surrounding environment. It offers flexibility as it can refill most cylinder sizes.

The device quickly fills the cylinder with pure oxygen saving energy costs and automatically shuts itself down when the cylinder is completely filled. The iFill can even top off partially filled cylinders. The device can be placed anywhere in the house and is very safe and simple to use.

Oxygen Refill Station

Refilling Oxygen TanksAn oxygen generator at your home can easily be upgraded to an oxygen refill station. This will allow you the convenience to fill the oxygen cylinders at your home for a fraction of the total cost. An oxygen tank refill system will save you time and money and will prove to be very feasible, fitting easily into your budget.

Oxygen refilling stations are very lightweight and small. They provide ambulatory patients the freedom to fill their oxygen tanks themselves. Moreover, the independence and convenience offered by these products makes them a preferred choice for many who continuously require a supply of oxygen. Such equipments also eliminate the need to frequently visit gas companies and save the cost of gas cylinder deliveries every now and then.

Continuous Flow Versus Pulse Dose Oxygen Therapy

If you find yourself in need of oxygen therapy you may receive a prescription for an Oxygen Concentrator. Concentrators emit a certain amount of enriched oxygen per minute in one of two ways: a continuous flow of oxygen or a pulse dose.

What is a Pulse Dose?

A continuous flow means that oxygen is flowing freely at the liters per minute (LPM) rate set by the user, whereas, a pulse dose is a smart technology that recognizes when the patient is taking a breath and emits the oxygen as needed. A pulse dose of oxygen is not sufficient for all those needing oxygen therapy. You should speak with your doctor to determine the correct dosage for you.

The Inogen One g2 is a Pulse Dose Oxygen Concentrator.

What Type of Machine Should I Use?

Some oxygen machines are not capable of pulse dose and some oxygen concentrators are not capable of continuous flow. There are two types of oxygen concentrators: home oxygen concentrators and portable oxygen concentrators. Home oxygen concentrators operate almost exclusively on continuous flow and are designed for use while at home and while sleeping. Portable Oxygen Concentrators are designed to carry around with you and they typically operate on pulse dose. However, some portable concentrators are capable of both types of oxygen therapy.

Eclipse 3 Portable Concentrator

The Sequal Eclipse 3 is Capable of Pulse Dose and Continuous Flow.

What is LPM?

Liters Per Minute or LPM is the rate at which the oxygen is being emitted. Oxygen concentrators are only capable of a certain LPM setting, so it is always wise to consider this during a purchase. Pulse oxygen machines typically go up to 5 liters per minute, but a portable machine that is capable of 5 LPM pulse oxygen dose may only be capable of 3 LPM at a continuous flow rate.

When purchasing an oxygen concentrator always consider the oxygen flow dosage and liters per minute settings that your doctor has recommended. There are so many choices on the market that there is an oxygen machine to fit your needs.


What is an Oxygen Bar?

Gone were the days when the word bar was defined as an establishment selling alcoholic drinks. Today you won’t just find liquids at a bar; you just might find an oxygen bar! Yes, an oxygen bar is technically an establishment that sells oxygen with different scents. They say that inhaling this will give anyone a relaxing and rejuvenating experience. Most oxygen bars would use aromatic oils as scents for their oils, but now, some bard use food grade products to provide guests with a wider selection of scents to choose from.
