Oxygen Therapy & Concentrator Resources

Help for COPD Oxygen Therapy and Concentrator Technology

Oxygen therapy raises the level of oxygen in the blood.  For some, blood oxygen levels only drop during exercise or during sleep.  For others, oxygen levels are consistently low and require concentrated oxygen 24 hours per day.  Regardless of your condition, the quickest way to feel better is to get in touch with other people with similar needs and educate yourself.

Oxygen concentrators and generators are used mainly as a breathing supplement for oxygen therapy.  They are also used for hyperbaric chambers and oxygen bars, but this resource is concerned with prescription medical grade breathing oxygen produced by HME type oxygen concentrators for people recovering from acute lung disorders or suffering from chronic lung disorders.


Oxygen Therapy Information

American Lung Association: Oxygen Therapy Fact Sheet
The American Lung Association is dedicated to prevention of lung disease and promotion of lung health.  This page gives general information oxygen therapy, what oxygen does in the body, ways of dispensing oxygen, benefits of supplemental oxygen, and a factual statement about recreational oxygen bars.

Merck Online Medical Library: Rehabilitation for Lung and Airway Disorders
This medical resource for patients and caregivers features a page on oxygen therapy.  Here you can find basic information on the applications of oxygen therapy, its benefits, oximetry, home oxygen, and safety.

Portable Oxygen: A User's Perspective
A helpful website created by Pete Wilson, who has been on oxygen therapy since 1996.  His website is made to educate oxygen therapy users and touches on subjects of oxygen providers, oxygen conservers, compressed oxygen, liquid oxygen, travel, and safety.

Patient Support Groups

COPD Support, Inc
A support group for Chronic Obstructive Pulmonary Disease, which can include Emphysema, Chronic Bronchitis, Chronic Asthma and others.  This is an open forum that allows people to learn from each other and provide support.  Find ideas and solutions dealing with COPD.

COPD Alert
This support and advocacy group is a huge resource for anyone who needs oxygen therapy.  Not only is there tons of COPD / Chronic Bronchitis information, there are also links to useful tools, current events, new procedures, books, medical library resources, articles and endless other help.

Emphysema Foundation For Our Right to Survive
A huge organization that supports people with Emphysema or COPD.  You can join email discussions with patients and doctors, find treatment information, browse medical pages, read explanations or interact with advocacy and awareness projects.

Oxygen Concentrator Technology

Wikipedia: Oxygen Concentrator
Wikipedia is a free online encyclopedia.  On this page, find out exactly how an oxygen concentrator works, its advantages over oxygen tanks, and other basic information.

Physics Central: How Things Work, The Physics of Everyday Life
This is a website where people can submit a question to Dr. Lou.  On this page he answers a question how does an oxygen concentrator work?  Understand their inner workings and how they produce oxygen from the ambient air.

Fiji School of Medicine:  Department of Anaesthesia
An article by Dr. Roger Eltringham from 1992 discusses the oxygen concentrator when it was newly developed for anesthesia and only available to hospitals.  This is the basis of all modern oxygen concentrators.

How do oxygen concentrators work?

Room air is drawn into the machine through a series of filters, compressed to a pressure of 4 atmospheres, or 20 psi,  and passed into a column containing zeolite, a "molecular strainer" of aluminium silicate. Nitrogen attaches to the zeolite, while oxygen passes through. Before the column becomes saturated with nitrogen, the flow of air is switched to a second column; the first column is vented to atmosphere, discharging most of the nitrogen, and the rest of the nitrogen is removed by back flushing the column with a small flow of oxygen from the second column. As the second column approaches saturation the process is reversed. The life of the zeolite crystals can be expected to be at least 20,000 hours which in most situations would give about 10 years' use. The gas exiting from the columns ( 95% oxygen) passes through a small reservoir chamber, and a flow control system, to the patient. Most domestic sized machines can produce a flow of up to 4 liters/minute of oxygen. Higher flows result in a loss of concentration, and most machines are flow-limited to prevent this from occurring.
