The low down on portable oxygen concentrators

Why do people use portable oxygen concentrators?

The key is in the name, the device is portable, meaning they are small, lightweight and can be easily manoeuvred. As wearable devices, they do not restrict your lifestyle and allow you to live your life in the way you choose. The portable oxygen concentrators run on DC or AC power but also have rechargeable batteries to accommodate travel. Providers look to get their products FAA approved so that you can legitimately travel with them.

Portable versus stationary oxygen concentrators

A stationary oxygen concentrator provides continuous flow oxygen with a large tank. They are designed for home use and are noted for working well whilst you sleep. Use of them is restricted to the house as you require an electrical outlet for them to work.

A portable oxygen concentrator on the other hand is based around being light and mobile and as well as being designed to be worn if you wish, it can run on batteries which brings a new dimension with the device as it makes it perfectly suited for both home use and when travelling.

Why may I need a portable oxygen concentrator?

The need for long-term oxygen therapy can occur due to several conditions and often require an evaluation of your lifestyle. There are a lot of options on the market available to help you and a popular choice is the portable oxygen concentrator. In general, the portable oxygen concentrator purifies oxygen levels. Conditions which often require you to need long-term oxygen therapy are:

  • Asthma
  • Chronic bronchitis
  • Chronic obstructive pulmonary disease
  • Cystic fibrosis
  • Heart failure
  • Pneumonia
  • Sleep apnea

What are continuous flow and intermittent flow portable oxygen concentrators?

Although the amount of oxygen you need is dependent on the diagnosis from your doctor, it is useful to understand the difference in flows.

  • Continuous flow – This delivers as the name suggests, continuously.
  • Intermittent flow – Also known as pulse flow, the delivery of oxygen can change according to your level of breathing.

Costs

Portable oxygen concentrators are not cheap, however, for the job they do you can easily weigh up that the devices are in fact cheap, but this depends on how much you value your life. Depending on your provider you may be able to buy or rent a device.

Renting is the cheaper option, and Medicare.gov believe that for the first three years of you using the rented equipment, you will pay just 20% of the cost plus any remaining Part B deductibles.
