Frequently Asked Questions
How do medical oxygen concentrators work?
The air that surrounds us normally contains a variety of gases and 21% of that mixture is oxygen. The oxygen concentrator draws the air through an intake valve, passes the air through filters to remove contaminants, and then through another molecular filter, which separates the oxygen from the nitrogen, argon and other contents. By extracting the oxygen, the concentrator delivers a flow of oxygen that will typically have a purity of up to 95%.
Portable or stationary: which is the best for me?
Oxygen concentrators for home oxygen therapy are available as either stationary or portable units. Stationary models are generally larger and heavier than their portable counterparts, however with increased size comes an increased oxygen flow rating. Stationary oxygen concentrators are capable of delivering anywhere from 3 to 10 liters per minute of oxygen while most portable models deliver 3 or less. Stationary models are suitable for in-home use and for patients who have been prescribed higher doses of oxygen.
Portable oxygen concentrators are designed to accommodate ambulatory patients who require a lower dosage of oxygen. These units feature optional power sources that allow them to draw power from a wall outlet, a vehicle adapter or a battery pack. Portable oxygen concentrators are especially convenient for patients who like to travel and some of them are even approved by the FAA for use while traveling by air.
What are the FAA regulations surrounding oxygen concentrator use in-flight?
In the United States, airlines that offer passenger service must comply with the Department of Transportation's rule "Nondiscrimination on the Basis of Disability in Air Travel". This ruling states that airlines must allow passengers in-flight use of respiratory assistive devices that have been approved by the Federal Aviation Administration (FAA).
Air carriers are responsible for ensuring that portable oxygen concentrators meet the FAA's standards. These standards address issues of safety such as radio interference and hazardous materials.

What do I need to know to operate my oxygen concentrator safely?
Your oxygen concentrator is a medical device that is only available with a prescription from your doctor. It is important to follow the manufacturer's instructions for its use carefully and consistently, and to use your oxygen concentrator as directed by your doctor. The following tips will assist you in safe operation of your oxygen concentrator.
- Never smoke while using your oxygen concentrator and be sure to maintain a distance of at least 8 feet from any source of open flame.
- Frequent use of your oxygen concentrator can cause dry skin around your nose. Moisturize prior to use using a water based lubricant. Petroleum-based products (such as Vaseline) should be avoided.
- Keep your oxygen concentrator away from sources of heat including space heaters, electric blankets, hair driers and cooking implements.
- Do not run oxygen tubing or electrical cords under carpets, furniture or blankets.
- Ensure that your electrical outlets are properly grounded prior to plugging in your oxygen concentrator.
- Never alter your oxygen concentrator's flow without first consulting your physician. Oxygen is a medication and should be taken exactly as prescribed.
How do I maintain my oxygen concentrator to ensure reliable service?
Your oxygen concentrator comes with an owner's manual that will explain the necessary steps to maintaining your particular device and ensuring that it provides you with reliable service. It is important to follow the recommended maintenance carefully.
