Medical portable oxygen machines are life-changing, innovative medical devices that allow people in need of oxygen to access clean supplemental oxygen conveniently. Since oxygen therapy can be administered on the go with these portable devices, they make it possible to travel, spend time with family and friends, and ultimately lead a productive life. 

Portable oxygen machines can be useful for ‌conditions requiring supplemental oxygen, including:

These devices are essential for relieving shortness of breath, increasing exercise capacity, improving quality of life, and reducing hospitalizations, for people with the conditions above. 

There are numerous different medical portable oxygen machines on the market, so how do you know which is the best in 2022? 

Why Do You Need a Medical Portable Oxygen Machine?

A medical portable oxygen machine offers tremendous benefits, especially to individuals with chronic lung disease. It generally improves the quality of life and decreases hospitalizations. A portable oxygen machine can help you:

  •  Improve your sleep: If you have chronic lung disease, your oxygen levels tend to drop during sleep, preventing you from getting a good night’s sleep. Therefore, a portable oxygen machine can help you sleep better. 
  • Move around easier: Recent developments include the emergence of compact and lightweight, portable oxygen machines that can be carried around just about anywhere, including car rides, baseball games, walks in the park, or picnics. They allow you to work, participate in physical activities, and never miss out on social events. 
  • Have better activity levels: Oxygen is essential to your body’s ability to generate energy. With these machines, you won’t have to worry about low oxygen levels since you’ll get sufficient oxygen supply for the stamina needed for daily routine and functioning. 
  • Have an independent lifestyle: Portable oxygen machines can make an independent lifestyle attainable. These easy-to-understand and easy-to-use devices can play a critical role in helping you lead an energetic and active lifestyle. They are essentially designed for mobility purposes, meaning you can carry them in your backpack or other accessories to move around easily. 

What Does It Do?

A portable oxygen concentrator provides clean, supplementary oxygen to people in need. This includes people with low oxygen levels or underlying conditions requiring oxygen therapy. It accomplishes this by receiving air, purifying it, and then distributing the enriched air. 

Air is primarily composed of nitrogen and oxygen. When air enters the machine, some of the nitrogen is filtered out, and the air is returned with a higher oxygen concentration. The device separates the nitrogen from the air to supply as much oxygen as possible.

Difference Between Oxygen Tank and Concentrator

A portable oxygen concentrator isn’t the same thing as an oxygen tank. An oxygen tank is a container of gas or liquid oxygen that you carry around. It holds a limited supply of oxygen that you use up as you breathe from it. On the other hand, an oxygen concentrator pulls in the air around you and filters out nitrogen to supply you with oxygen. It, therefore, doesn’t contain a supply of oxygen but rather filters the air around you.

Pros and Cons: Oxygen Concentrator

Each option has its pros and cons. A notable advantage of the medical portable oxygen machine is the ability to use and filter the already available air to produce supplemental oxygen. Therefore it does not require refilling. This also makes them comparatively lightweight and easier to carry around. Apart from providing an unlimited oxygen supply, these devices come in various sizes, models, and styles, which makes them travel-friendly. However, they need batteries to run, can be noisy, and are more costly to acquire and maintain.

Pros and Cons: Oxygen Tank

On the other hand, oxygen tanks come with distinct benefits that portable concentrators do not offer. For instance, no power is required to function, there are lower initial costs, and they are pretty quiet while operating. However, they are relatively heavy, have a limited oxygen supply, and incur greater costs in the long run since they need refilling.
