What Is A Oxygen Concentrator?

An oxygen concentrator is an electric oxygen delivery system about the size of a large suitcase. The concentrator separates oxygen and nitrogen from room air, discards the nitrogen and delivers the oxygen with up to 95% purity to the user through a mask, or more commonly through a nasal cannula.

An oxygen concentrator must be prescribed by a patient’s physician.  The doctor will prescribe an exact flow rate (in liters per minute) for the patient for various activities.  For example, a patient’s flow rate while at rest will vary from the flow rate
prescribed for exercise. The doctor will also prescribe the length of time the patient should use oxygen each day.

How an Oxygen Concentrator Works

Oxygen concentrators make use of adsorption, a phenomenon in which gas molecules stick temporarily to surfaces. Some molecules stick better than others to each surface, a fact that makes it possible to use adsorption to separate various molecules from one another. The heart of an oxygen concentrator is a porous material called zeolite. With a vast
network of tiny holes, zeolite resembles a miniature Swiss cheese, and presents an enormous amount of surface area on which gas molecules can adsorb. Nitrogen molecules stick more often to zeolite than oxygen molecules because
nitrogen molecules bind more strongly to the zeolite surface than do oxygen molecules. Zeolites tend to concentrate oxygen in the air by removing most of the nitrogen molecules. An oxygen concentrator takes in room air, passes the air through a filter to remove any dust particles and raises the air to a pressure of 20 pounds psi by a compressor (see
Figure 1). To extract as much nitrogen as possible, the pressurized air is pumped into a canister containing zeolite (often called “sieve bed”). The zeolites adsorb most of the nitrogen from this air, leaving nearly pure oxygen for breathing. After about 20 seconds, the zeolites become saturated with nitrogen and cannot extract any more. At this point, a solenoid valve opens to reduce the pressure on the canister to atmospheric pressure, and the nitrogen begins to be released prior
to beginning another cycle. This canister switching process is under electronic control. Some oxygen concentrators employ microprocessors and actual oxygen sensing circuitry that monitors the oxygen percentage in the air and detects when the output gets too low. To keep oxygen flowing at all times, a typical oxygen concentrator has two separate
zeolite-filled canisters. At any given time, one canister is providing oxygen for breathing, while the other is regenerating by releasing its stored nitrogen into the air.

Who Uses an Oxygen Concentrator?

Many people have cardiac or pulmonary deficiencies caused by disease, life style (smoking) or aging.  This means that their heart or lungs or both are unable to deliver an adequate amount of oxygenated blood to their vital organs and tissues. In the case of a chronic obstructive pulmonary disease (COPD) such as bronchitis, emphysema, asthma, asbestos damage and cystic fibrosis, the effective pulmonary surface area over which blood/air oxygen exchange can occur has been diminished. This situation can be overcome by increasing the percentage of oxygen to the patient. In the case of a cardiac insufficiency, not enough oxygenated blood is being pumped to the tissues. This situation can be improved by increasing the percentage of oxygen in the blood, which can be achieved by increasing the percentage of oxygen in the air. An oxygen concentrator can be an excellent device for treating these deficiencies in not
only the clinical environment, but in the home to improve the user’s overall quality of life. In addition to an oxygen concentrator that they use in the home, many oxygen users will also use an oxygen cylinder, which allows them to be active outside the home. The oxygen cylinder also serves as backup oxygen supply should there be a power failure in
the user’s home or a concentrator malfunction.
