What Is a Portable Oxygen Concentrator?

A portable oxygen concentrator (POC) is a medical device that helps to improve  blood oxygen levels. You can either plug them into an electrical outlet or power them with a battery.

POCs receive air, purify it and then deliver it to your respiratory system. Air is mostly made up of nitrogen and a small amount of oxygen (21%) before it goes into the concentrator, and after going through the concentrator, its oxygen concentration increases drastically.

This medical device is usually prescribed by healthcare providers to individuals with chronic and acute lung conditions that cause blood oxygen levels to drop too low. Some of these conditions are:

  • - Chronic obstructive pulmonary disease (COPD)
  • - Severe asthma
  • - Lung cancer
  • - COVID-19 infection and long COVID.

How Portable Oxygen Concentrators Work

POCs work by using a compressor, filters and tubing to deliver purified oxygen to your nose or mouth through a nasal cannula. The two types of POCs are pulse dose and continuous flow.

Pulse dose POCs deliver oxygen only when you inhale, which saves battery life and makes them lighter and quieter. However, they may not be suitable for people who breathe through their mouth or have very low blood oxygen levels.

Continuous flow POCs deliver a constant stream of oxygen, regardless of your breathing pattern, which may be more comfortable and effective for some people. However, they are heavier, louder, and use more power than pulse dose POCs.

Some POCs have both pulse dose and continuous flow modes, which allow you to switch between them depending on your needs and preferences.

How to Choose a Good Portable Oxygen Concentrator

If you need a POC, there are many factors that you need to consider before committing to one device. Here are some of the things you should check:

Equipment flow rate:

This is the amount of oxygen that the POC can deliver per minute. It can be measured in liters per minute (LPM) or milliliters per minute (mL/min). The flow rate you need will depend on your doctor’s prescription and your activity. You should always aim to get a POC that offers a flow rate higher than your needs.

Battery life:

If you’re an active person who spends a lot of time outdoors, you’re going to need a POC with a longer battery life. However, if the only times you’re going to use your POC out of your home is when running quick errands, you could go for a device with a shorter battery life.

Oxygen delivery modes:

As we’ve mentioned, there are two main modes: continuous flow and pulse dose. Pulse dose is a more power efficient mode that is only triggered when you exhale. However, the continuous flow mode is more suited for people who have higher oxygen needs.

Weight and size:

Some POCs are lighter and smaller than others, sometimes at the expense of battery life, and some come with carrying cases or carts to make them easier to transport. Pick one that’s light enough for you to carry around for extended periods of time.

Noise level:

If you use your POC while sleeping and when doing activities that need your full focus, the lower the noise level the better!

Oxygen purity level:

Most POCs have an oxygen purity level that ranges from 87% to 99%. The purity level that you need will depend on your specific health condition. You should ask your doctor what’s the ideal level for you.

Ease of use and maintenance:

When picking a POC, look for one that’s easy to use and doesn’t need a lot of maintenance. Choose a device that fits well into your daily life, making things simple and requiring minimal effort to keep it running smoothly.

Choosing a good POC can be challenging, but also rewarding when you make the right decision. Make sure to compare different models and brands, and to get advice from experts before you make a final decision.

What’s the Difference Between a Home Oxygen Concentrator and a Portable Oxygen Concentrator?

If you need supplemental oxygen therapy, you may have heard of two types of devices that can deliver concentrated oxygen to you: home oxygen concentrators and portable oxygen concentrators. There are many differences between them that makes them ideal for different target audiences. These differences are:


One of the most obvious differences between home and portable oxygen concentrators is their size. Home oxygen concentrators are larger and heavier than portable ones, because they have bigger systems that can produce higher amounts of oxygen.

Home oxygen concentrators are usually placed in one room and have wheels to move them around if needed. They aren’t designed to be taken outside of your home or office, while portable oxygen concentrators are designed to be carried around and be used everywhere you go.


Home oxygen concentrators can weigh anywhere from 30 to 60 lbs, while portable oxygen concentrators can weigh as little as 2 lbs or as much as 20 lbs, depending on the model and battery life.

Oxygen Output

Home oxygen concentrators can provide a continuous flow of oxygen at rates up to 10 LPM, and they are suitable for people who need very high oxygen levels, or those who use other devices such as CPAP or BiPAP machines.

On the other hand, portable oxygen concentrators can provide oxygen at rates up to 5 LPM, making them more suitable for people who need low to moderate levels or supplemental oxygen.

Power Choices

Home oxygen concentrators need to be plugged into an electrical outlet to work, while portable oxygen concentrators can run on batteries, or while plugged in directly to a power source.

Some home oxygen concentrators models do have backup batteries that can be used in case of power outages, but they’re not meant to run on batteries for long periods of time.


Home oxygen concentrators are generally cheaper than portable ones, because they have simpler designs and lower maintenance costs. Since portable oxygen concentrators have more complex designs and have technology that allows them to be used in high altitudes, they tend to be substantially more expensive. 

Which One Is Right for You?

The choice between a home or a portable oxygen concentrator depends on your individual needs and preferences. You should consider your lifestyle, activity level and travel plans, as well as your supplemental oxygen needs.

If you need high levels of oxygen or your priorities are affordability and simplicity, a home oxygen concentrator may be a better option for you. If you only need low to moderate levels of oxygen or your priorities are mobility and flexibility, a portable oxygen concentrator may be the best choice for you. The best type of oxygen concentrator is the one that meets your medical and personal needs.

Benefits of Using a Portable Oxygen Concentrator

There are many benefits for those using a POC, especially seniors and people with chronic and acute breathing problems. Some of these benefits are:

Provide Oxygen Therapy for Seniors

As we age, our lungs may not function as well as they used to. Seniors are more likely to suffer from chronic lung diseases that cause shortness of breath, fatigue, chest pain and low oxygen levels.

Oxygen therapy can help improve the symptoms and quality of life of seniors with lung diseases. It can also decrease the risk of complications derived from these conditions, such as heart failure, pulmonary artery hypertension, and cognitive impairment.

POCs are ideal for seniors who need oxygen therapy, because they are portable, lightweight and easy to use. They allow seniors to maintain their independence and mobility while receiving oxygen therapy at home and on the go.

Helps with Breathing Problems

Some common causes of breathing problems are allergies, infections, anxiety, obesity, smoking, and exposure to air pollution. These issues can interfere with your daily activities and affect your mental and physical health.

Oxygen therapy can help relieve breathing problems by increasing your blood oxygen levels. This can improve lung functions, reduce inflammation and enhance energy levels.

COVID-19 recovery

COVID-19 can cause mild to severe symptoms, such as fever, cough, sore throat, loss of taste or smell and difficulty breathing. In some cases, COVID-19 can lead to pneumonia, acute respiratory distress, organ failure, and death.

Oxygen therapy is one of the main treatments for COVID-19 patients who have low oxygen levels or difficulty breathing. It can help with oxygenation, reduce the work the patient needs to do to breathe properly, and prevent further lung damage.

POCs are beneficial for COVID-19 patients who are recovering at home or in isolation facilities. They can provide continuous or intermittent oxygen therapy without requiring hospitalization or specialized equipment.

Blood Oxygen Levels

Normal blood oxygen levels range from 95% to 100%. Low blood oxygen levels, or hypoxemia, can be caused by several factors, such as lung disease, heart disease, anemia, sleep apnea, high altitudes, and carbon monoxide poisoning.

Hypoxemia can have serious consequences, such as tissue damage, brain damage, and death. Oxygen therapy can help increase blood oxygen levels and keep them at a stable level.

Some POCs have built-in pulse oximeters that display your blood oxygen levels on a screen, and alert the users if their blood oxygen level drops below a certain threshold.


Do You Need a Prescription for a Portable Oxygen Concentrator?

The answer is yes. The US Food & Drug Administration (FDA), oxygen concentrators are considered a Class II Medical Device. This means that you must have a valid prescription from a board-certified doctor in order to purchase one.

How Much Does a Portable Oxygen Concentrator Cost?

The price of a POC ranges from $2,000 to $4,000, but Medicare and private insurances may cover part of the cost. Also, you can often find deals on portable oxygen concentrators at Sleeplay.

Does Insurance Cover Portable Oxygen Concentrators?

POCs are considered durable medical equipment (DME) by Medicare, Medicaid, and most private insurance plans. If you have original Medicare, Part B will cover the costs of the oxygen equipment and accessories prescribed by your doctor for home use.

Can I Use My Portable Oxygen Concentrator When I Fly?

Most POCs are FAA-approved for in-flight use. However, most airlines require you to let them know in advance and to submit a doctor’s report to verify that you need to use the POC on the plane. Always make sure to check your airline’s policies before traveling with your POC.
