Are you curious as to how an oxygen concentrator operates? People with low blood oxygen levels get relief from oxygen devices. In the past, these were large pieces of equipment that made it challenging for patients who required oxygen therapy to receive it outside of their homes. Modern oxygen generators, on the other hand, are more compact, lighter, and made primarily for portability. We’ll discuss oxygen concentrators and their operation in this article. You can get an oxygenator from a medical oxygen supplier if your doctor has prescribed one or you believe you need one.

Medical equipment called oxygen concentrators helps persons whose blood oxygen levels are low. They are powered either by a battery or by putting the device into an electrical outlet. A battery must be charged by plugging it into an electrical outlet if one is utilised. The majority of concentrators also have an adaptor so you may use it while driving.

Air is taken in, cleaned, and then distributed using an oxygen concentrator. Air is composed of 80% nitrogen and 20% oxygen before entering the concentrator. When the air is sent through an oxygen concentrator, it is converted to 90 to 95 % pure oxygen and 5 to 10 % nitrogen. Since it’s challenging to obtain that amount of oxygen without the aid of a medical device, the nitrogen is separated to give the patient the greatest dose of oxygen possible.


An oxygen concentrator is what? It is a medical device that provides oxygen to people who have breathing disorders. The oxygen machine provides the necessary oxygen to a person whose blood oxygen level is below normal.

An oxygen concentrator operates in a fairly straightforward manner. The device draws air in, which then passes via a compressor. The compressed air enters a two-pronged sieve bed filter device. Nitrogen is removed from the first sieve bed when compressed air is introduced, while oxygen is pushed into the tank. The compressed air switches to the second sieve bed once the first bed has been filled with nitrogen.

The first sieve bed’s excess nitrogen and a small amount of oxygen are released back into the atmosphere. When the second sieve bed is filled with nitrogen, the process reverses. As a result, the tank receives a constant supply of concentrated oxygen. After leaving the product tank, the oxygen travels through plastic tubing to a nasal cannula or mask that aids in the patient’s effective oxygen absorption.

When Do People Need An Oxygen Concentrator?

According to pulmonologists, the following circumstances necessitate the use of an oxygen concentrator:

when a person’s oxygen saturation falls below 94% and they are only mildly or moderately ill. Asthma, the flu, COVID 19, lung cancer, chronic obstructive pulmonary disease, congestive heart failure, chronic bronchitis, pulmonary fibrosis, and congestive heart failure could all contribute to this problem. In this instance, Philips oxygen concentrators are the most affordable and dependable option for home oxygen therapy. An oxygen concentrator can also be used by people whose oxygen saturation has fallen to 85% or lower. However, this is just suggested as a stopgap measure. Such people need to be admitted to a hospital and given access to an oxygen cylinder that has a higher flow of oxygen.

People admitted to the ICU should not utilise oxygen concentrators due to the delicate nature of their situation.

How do Oxygen Concentrator Works

to know about how do oxygen concentrator work you have to read full article. There are several pieces that make up a portable oxygen concentrator. The major components include a sieve bed filter and a compressor. Air that has been filtered and delivered to the concentrator by the compressor has been compressed and is then continuously delivered.

The sieve bed filters receive compressed air. Since it is the component that takes nitrogen out of the air, the sieve bed filter is crucial. The nitrogen is taken out of the air by a substance called Zeolite, which is a minuscule six-sided cube with holes on each side, which is in the sieve bed.

The concentrator contains two sieve beds. Air is forced into the first sieve bed after being first compressed in the concentrator. The product tank is filled with oxygen. Nitrogen is then added to the first sieve bed. The second sieve bed is then filled with compressed air after switching the gas flow. The compressor for the first sieve bed is moved to the adjacent room, and the product tank’s air is redirected into the first sieve bed.

The Zeolite releases nitrogen as a result of the pressure drop from the first sieve bed and the weakened oxygen. The room’s ordinary air is released once the oxygen and nitrogen recombine. Following compression, the air is routed to the second sieve, where oxygen is then passed through it and into the product tank. After a few seconds, the first sieve serves as the starting point for the entire process. The cooling system, which prevents the portable oxygen concentrator from overheating, and the nasal cannula, which provides the filtered oxygen after it has been put through all of the sieve bed filters, are other crucial components. The cannula enhances the absorption of oxygen.


If you haven’t used an oxygen concentrator before, you could find it challenging. But anyone can complete the process because it is so straightforward. Before putting on your mask or nasal cannula, you only need to set up the machine correctly, turn it on, and adjust it to the recommended flow rate.

  • Place the oxygen generator a few feet from any furnishings.
  • Start the machine 15 to 20 minutes prior to usage so that it can start dispensing an exact air concentration.
  • Before starting your treatment, straighten out any kinks or bends in the tubing.

Use the mask if you want low oxygen levels. Insert the nasal cannula if the level is high. before the use, you need to know how do oxygen concentrator work

Comparing liquid medical oxygen, oxygen cylinders, and oxygen concentrators

We frequently ponder whether oxygen concentrators or cylinders would be a better fit for our needs.

Oxygen concentrators are the best and most dependable choice for urgent oxygen therapy, whether at home or while you’re travelling to the hospital. Portable oxygen cylinders for home usage are cumbersome to use flexibly, especially when travelling.

Speaking of costs, oxygen concentrators are significantly more affordable to maintain even though they are more expensive than oxygen cylinders. They operate on electricity and don’t require refilling as oxygen cylinders do. In addition, accessories like oxygen cylinder regulators, filters, and tubes are pretty pricey.

However, oxygen cylinders function better when it comes to critically ill individuals who require higher doses of pure oxygen. Compared to oxygen concentrators, which can only produce 5–10 litres of oxygen per minute, they can pump 40–45 litres of oxygen per minute.

For patients who require more than 6 litres of oxygen per minute, liquid medical oxygen, which has a purity of 99.5%, is utilised. When you are at home, this sort of oxygen is provided through a stationary concentrator, but when you are travelling, it is delivered through an ambulatory tank.

in this article, we will discuss how oxygen concentrator work and what is it. I hope you will share this with your friends
