Online Oxygen Concentrator Buying Guide

Oxygen Concentrators
An online buying guide for oxygen concentrators

At-home oxygen therapy is important for individuals with chronic respiratory illnesses. After receiving your prescription, it is important to select an oxygen concentrator that meets your specific needs and lifestyle. While some doctors work with suppliers to get your first concentrator, this buying guide provides useful tips for shopping online.

Type of Respiratory Illness Treated 

Doctors prescribe oxygen concentrators for a number of respiratory illnesses. They include:

  • chronic obstructive pulmonary disease (COPD)
  • pneumonia
  • asthma
  • cystic fibrosis
  • lung disease

Your prescription will include settings for LPM, or liters per minute, and whether or not you require continuous flow or pulse dose oxygen. These settings depend on the severity of your illness. When choosing an oxygen concentrator, make sure you select one that will fit your prescription.

Factors That Affect Choosing An Oxygen Concentrator

How Active Are You?

Whether you travel frequently for work or enjoy leisurely activities such as walking or biking, oxygen therapy should not limit your lifestyle. Portable oxygen concentrators are the best choice if you need to take your therapy on the go. These oxygen concentrators are lightweight and compact, meeting the demands for your oxygen therapy even while you are not at home. 

Are You A Frequent Traveler?

As mentioned, an active lifestyle may also include frequent travel. Ensuring your portable oxygen concentrator meets the demands of travel is important. A durable carrying case, extra nasal cannulas and the proper AC/DC power cords are necessary for therapy on the go.

One of the most overlooked factors, however, is power. Portable oxygen concentrators use rechargeable lithium-ion batteries to provide therapy. When selecting your device, make sure the battery life meets your travel requirements. It may also be a good idea to purchase additional batteries for longer trips or unexpected power outages.

Most portable oxygen devices are approved by the FAA for in-flight use.

How Much Oxygen Do You Need?

Your oxygen needs will depend on your prescription and the severity of your respiratory condition. Portable oxygen concentrators will deliver therapy in pulse doses, between 1-6 pulses per breath. Home oxygen concentrators, on the other hand, deliver oxygen continuously between 1-10 liters per minute (LPM).

It is important to note that a pulse dose setting of 2 is not the same as a continuous flow setting of 2. Prior to changing your settings, be sure to speak with your doctor to ensure you are getting accurate therapy.

Here are some setting ranges among the most popular oxygen concentrator brands.

Popular Oxygen Accessories and Supplies

Your oxygen therapy is more than just an oxygen concentrator. You will also need accessories and supplies to keep oxygen therapy consistent and effective while managing your respiratory illness. Most supplies need to be replaced over time, so you will always need to replenish when accessories such as nasal cannulas get old, or oxygen tubing begins to crack.  Here are some of the most popular accessories and supplies you will need for oxygen therapy.

Nasal Cannulas

Nasal cannulas can wear out over time, and you will need to replace. You can feel when they become less comfortable or less secure or if you start to experience irritation from the contact on your nostrils. You want to make sure you choose a cannula that meets your specific needs for comfort and flexibility.  Additionally, you can even choose a nasal cannula that is latex free. Choose from some of the most popular nasal cannulas.

Oxygen Tubing

Oxygen tubing can begin to crack or develop fissures which can compromise the effectiveness of your oxygen therapy and reduce oxygen pressure. Select oxygen tubing that fits your needs in terms of length. You can choose tubing that is extra-long so you can move around freely and shorter tubing, so you don’t have too much tubing to tangle. You can also find tubing that is kink-free. Choose from a variety of oxygen tubing.

Batteries And Power Supply

For patients who use portable oxygen concentrators, backup batteries become an essential part of their oxygen therapy equipment. While many portable oxygen concentrators have internal batteries, they may last for only so long. External batteries help patients extend the charge of their portable oxygen concentrators. Other types of power supplies are also available for charging up a portable oxygen concentrator from your car. See what batteries and power supplies are available.

Pulse Oximeters

Anyone managing a respiratory illness can practice essential self-care with  the help of a pulse oximeter. These simple devices lets anyone measure their blood oxygen level. When someone does not receive the necessary amount of oxygen through breathing, blood oxygen levels drop, often without a patient realizing it. A pulse oximeter lets you quickly and easily measure blood oxygen saturation to know when you need oxygen. Find pulse oximeters for your self-care.
