What does an oxygen concentrator do?

An oxygen concentrator is a device used by people who experience breathing difficulties and require additional help and support to maintain oxygen levels inside their body. The concentrator is a unit that uses the ambient air around you to provide you with a pulse flow of concentrated oxygen to boost the efficiency of each of your breaths.

Typically, these kinds of units are designed for use for people who are experiencing the symptoms of emphysema, chronic obstructive pulmonary disease or COPD, or whose lung health otherwise requires support in getting the most from each breath.

An oxygen concentrator is a piece of machinery normally recommended by a medical professional such as your GP. It is unwise to purchase a unit without medical advice and ongoing support to provide you with the information you need to maximise the efficiency of your personal unit.

How does a portable oxygen concentrator work?

The unit works by removing nitrogen from ambient air and producing oxygen rich air through tubes typically to the nose, or via a mask to the nose and mouth. Units and their designs differ to ensure they deliver optimum performance depending upon your needs. You may find a facial mask is better suited to your condition than nasal tubes, for example.

Portable oxygen concentrators use PSA or pressure swing technology, replacing the need to for a pressurised oxygen tank. This makes them ideal for travelling as they are more lightweight and less dangerous. The unit increases pressure within its cylinders to concentrate the oxygen it takes from the ambient air. Once it has concentrated enough oxygen, that oxygen – as well as a small amount of water and other elements including carbon dioxide – move into a secondary cylinder where the pressure is equalised and delivered through the tubing to the user. Portable units are operated by battery for ease of movement.

How long do home oxygen concentrators last?

It is difficult to provide an accurate estimate for how long your home oxygen concentrator will likely last. Some people have reported using their units without problems for up to 10 years. Ultimately, it will depend on how often you are using your unit and whether it is regularly maintained and repaired. Like any machinery, ensuring it is working at peak performance is the key to its longevity and to maximising the benefits you receive from it.

Generally, once the oxygen purity your unit is producing drops below 80% it is no longer a viable unit and must be either repaired or replaced. Typically, you will notice the battery in your portable unit beginning to fail after approximately 80 or so full charges. It will still contain charge but its ability to charge your portable unit efficiently will begin to degenerate and you will receive less and less time between battery charges.

Your unit also contains filters which need to be regularly cleaned and replaced. Depending on your unit, you may be able to undertake some of these maintenance duties yourself, however, some filter changes will need to be done by a service technician.

Sove CPAP Clinic network can assist with repairs and maintenance needs on your unit with fully credited service technicians available for every type of machine we provide.
