What is portable oxygen concentrator and how does it work?

Oxygen concentrator is seldom seen in our daily life. However, for some patients, they are very useful and can save their life in acute situation. Today, we will explore what portable oxygen concentrator is and any things you need to know about it.

How Do I Qualify for A Portable Oxygen Concentrator?

How Do I Qualify for A Portable Oxygen Concentrator?


Generally speaking, oxygen concentrator serves for patients with COPD, that is, chronic obstructive pulmonary disease. In serious stage where patients should go through in the hospital, they are likely to suffer obvious carbon dioxide retention, which medical oxygen concentrator can in-time discharge so as to save their lives. After discharged from the hospital, although patients get better than before, the carbon dioxide may still remain higher than common level. It is portable oxygen concentrator that helps patients lead a safe and healthy live during this stage. It is available for patients at any time and any where. Some need it for about two hours per day, the other may even use it all the night.


New Coronary Pneumonia generally refers to pneumonia caused by a Covid-19 virus. In common, if the patient is asymptomatic or has a relatively mild novel coronavirus infection, it is not necessary to use a portable oxygen concentrator. However, once the patient has symptoms of dyspnea, it can be used to assist breathing. It can effectively manage the short breathing rhythm and breathing depth of sick lung so as to increase pulmonary ventilation as well as respiratory function. 

Furthermore, if the patient unfortunately infected with a severe novel coronavirus, he should go to hospital immediately. If the symptoms of respiratory depression cannot be effectively improved by drugs alone, a  oxygen concentrator can be a supplementary therapy.

Short Breath Due to Poor Quality Air

Recent mildfire from Canada may raise the incidence rate of respiratory disease, such as short breath and asthma.

Normally, oxygen concentrator is not required. However, if the patient, after active treatment, still has negative symptoms such as extreme respiratory muscle fatigue, decreased respiratory rate, difficulty speaking, decreased consciousness, oxygen concentrator should be used immediately under the guidance of a respiratory physician.


ARDS is called acute respiratory distress syndrome. For patients with acute respiratory distress syndrome, the application of medical oxygen concentrator can be considered in the early stage. It may correct hypoxia because the patient’s mind is very clear at this time.

What Is A Portable Oxygen Concentrator?

Portable ventilators are generally so small in size that it is suitable for use outdoors and even at home. Portable oxygen concentrator are usually powered by direct current or lithium batteries with low power consumption and noise. It is mainly used for providing therapy against low atmospheric pressure, and give people a feeling of relaxation and comfort. Besides, portable oxygen concentrator can also provide additional care for patients with breathing problems in daily life.

How Does It Work?

How Does It Work?

The working principle of an oxygen concentrator is relatively simple. When the air passes through the compressor, the device pull it in. Then, compressed air enters a sieve bed filtration system with two pointed ends. When compressed air enters the first sieve bed, nitrogen is removed and oxygen is forced into the storage container. After the first bed is full of nitrogen, the compressed air is transferred from the first storage container to the second sieve beds. Finally, the oxygen concertrator output purified air.

About Oxygen Output Volume

Oxygen supplied  portable concentrators can be dispensed in one of two ways. One is continuous flow, the other is pulsed flow delivery. Although both oxygen delivery methods are capable of delivering medical-grade oxygen directly to the user, the output volume of them is measured in different approaches.

A continuous flow is dispensed without any interruption, stopping only if the concentrator is switch off. In other words, regardless of the patient’s breathing pattern, these continuous flow concentrators will deliver the same amount of oxygen to the patients. This approach of oxygen delivery allows the output flow rate to be measured in constant volume LPM (liters per minute).

In contrast, pulse oxygen portable concentrators are designed to dispense oxygen while the device senses an inhalation of patient. That is, when the patient inhales through the cannula, a pulse dose of oxygen, called a bolus, is triggered and released. Pulse dose oxygen device have settings available to adjust how much oxygen is outputted each minute. As the setting is increased, the size of the dispensed oxygen bolus also develop.

About Light Weight

About Light Weight

Easy Travel

The lightest portable concentrators usually weigh about 5 pounds or less. They allow you quickly and discreetly to pack them in backpack with light weight. Beside, you can take them almost anywhere with ease.

Reduced Social Stigma

Compared with big home oxygen concentrate, a portable concentrator can reduce the social stigma faced by oxygen patients. Firstly, it is too small to look like a medical device at first glance. Even most people don’t even know what it is and tend to see it as common high-tech machine. 

With the help of portable oxygen concentrator, oxygen patients acts capably as anyone else. If you put it in configured bag, the oxygen portable concentrator may be more secret when using it.

About Noise:Whisper Quiet Oxygen Concentrators

If you notice that the oxygen concentrator is not as quiet as it was when the unit was new, it may needs maintenance.

Firstly, clean the air filters to make sure they are not clogged. If the air filter is clogged, the compressor has to works so harder that it makes more noise. Secondly, if you need oxygen generator in night sleeping and is disturbed by its noise, please put it in a remote distance and use it with a longer tube. Or you can directly seek to professional maintenance assistance.

About Size

As usual, portable concentrators take up less space than other oxygen devices. It is highly recommended for those who live in small apartments because it, to the uttermost degree, saves rooms to leave more living space for you.

About Continues Flow

Continuous-flow oxygen delivery is not trigger by inhalation, but continuously output oxygen flow in a constant output way regardless of patient’s breath. Traditional continuous-flow home oxygen inhalers tend to be heavier, which makes things more difficult when you travel. Fortunately, there are portable oxygen concentrators coming with  continuous flow options, so you can still enjoy abundant oxygen delivery during journey. 

How Long Do You Keep A Portable Oxygen Concentrator?

Most portable oxygen concentrators is durable between four and seven years, depending on how patients take care of their mahcine. Unavoidably, portable oxygen inhalers may take a lot of bumps when traveling with patients, which also reduces its lifetime. To extend the lifetime, please make sure that you pack it smartly when you carry it outdoor.

What Is the Cost of A Portable Oxygen Concentrator?

Portable oxygen concentrator is priced at about two thousand and five hundred dollars. In some cases, medicare insurance cover part of above cost.

The reason is that FDA try to make sure oxygen concentrators are appropriately distributed to patients with genuine medical requirements, such as chronic obstructive pulmonary disease (COPD), respiratory distress syndrome, respiratory distress syndrome, asthma, pneumonia.

Which Is Better

Oxygen Tank Vs. Oxygen Concentrator

An oxygen tank and an oxygen concentrator differs on how the oxygen is delivered. For the former, limited oxygen is stored in the tank. The latter, an oxygen concentrator, produce medical-grade oxygen by filtering and concentrating the surrounding air. As long as there is power for machine , oxygen concentrators can offer unlimited oxygen.

Oxygen Concentrator Vs. CPAP Machine

Oxygen concentrators and CPAP machines differ on functions. The former mainly serve respiratory conditions which cause low oxygen levels in the blood. CPAP machines mainly keep the airway open during sleep, preventing interruptions in breathing caused by sleep apnea.

Home Oxygen Concentrator Vs. Portable Oxygen Concentrator

As the name shows, this is a portable oxygen concentrator that can be used at home or carried outdoor. They tend to be more lighter and compact, with pulse-dose technology available. In contrast, home oxygen concentrators need to be plugged into home electrical outlet to deliver oxygen continuously.
