What is a Portable Oxygen Concentrator? (Benefits, Uses, and Limitations)

When you’re struggling with a lung disease or a breathing disorder that requires you to use supplemental oxygen, there are some things you can do to make it easier to cope with these issues. Oxygen offers many benefits and now that you have the option of a portable oxygen concentrator, you can now breathe easier while you enjoy your freedom and independence.

What is a Portable Oxygen Concentrator (POC)?

Portable Oxygen Concentrator definition: A POC is a medical device that helps individuals with a low level of blood oxygen. You can plug them into an electrical outlet or power them by a battery. If the battery is spent, you’ll need to charge it back up by plugging it into the electrical outlet. Many of the portable oxygen concentrators also come with an adapter so you can use your device while driving.

Portable oxygen concentrators receive air, purify it and then distribute the changed air. Air is made up of mostly nitrogen and some oxygen before it goes into the concentrator. After going through the concentrator, the air comes out almost all oxygen and very little nitrogen. The device then separates the nitrogen to give the individual as much oxygen as possible, since it’s hard to get the perfect percentage of oxygen without using a medical device like this.

While there are other types of medicine used in tandem, like corticosteroids, inhalers and prescription medicines, supplemental oxygen use has stayed a staple in lung disease treatment for its ability to offer continued respiratory support for individuals struggling with their oxygen intake on a daily level.

Portable Oxygen Concentrator Limitations

While there are many notable positives of a POC, there are a few drawbacks and limitations as well. For instance, POCs aren’t cheap and even the most basic device can cost more than $2,300. Also, Medicare or Medicaid may not cover this high upfront cost because of the industry’s preference for the less expensive supplemental oxygen tanks.
