What is oxygen therapy?

Oxygen therapy is hyperbaric oxygen delivered in a barochamber.

Put very simply it's breathing a higher concentration of oxygen than you would in normal air at pressure.

The air we normally breathe consists of 21% oxygen, 78% nitrogen and the remainder is comprised of carbon dioxide and noble gases. During your oxygen therapy session you will breathe nearly 98% oxygen for one hour. The majority of people will use a face mask, for children, and some adults, a clear hood is used and this is made airtight by way of a soft rubber seal that sits quite comfortably around the neck.

The oxygen is given in a barochamber; this is an airtight vessel just like a commercial aircraft and like an aircraft the air pressure inside it is controlled. Depending on what you find comfortable you will breath oxygen between one and half to two times the normal atmospheric pressure found at sea level. The benefit of breathing oxygen in a pressurised environment is that your body is able to absorb more oxygen. 

 

Although the damage caused by neurological conditions cannot be prevented or cured by oxygen therapy, many people throughout the world find that it reduces the severity of their symptoms.

"I have multiple conditions; fibromyalgia, arthritis and lymphocytic leukemia. Oxygen Treatment has been of great help for all of these.  The first two weeks of my initial block I started to sleep better. Having oxygen has given me a feeling of wellbeing I had not experienced for a long time."

What happens during a session?

Oxygen therapy is simple and non-invasive, you will be seated in a purpose built chamber with no more than three other people, we have currently limited the numbers using the chamber to maintain social distancing.

You will enter the Centre wearing an oxygen mask, you can purchase one from us or you are welcome to borrow a Centre mask, borrowed masks are thoroughly cleaned, sanitised and stored hygienically before and after each use. 

 

Once in the chamber you will attach the oxygen supply and exhaust pipes to your mask - this will have been demonstrated to you by one of our lovely volunteers. The entire time you are sat in the chamber you will be on a completely separate air supply to every one else. 

The session is then conducted in the following three stages; 

Compression 

After the chamber door is closed there will be some noise as air is added and the pressure inside is increased. 

It is at this point that your air supply will be switched from normal air to nearly pure oxygen. 

The chamber will begin to feel warmer and most people experience a fullness in their ears; similar to when an aeroplane descends. 

You may need to equalise your ears to avoid any discomfort. 

It can take between 10 and 20 minutes for the chamber to reach the correct pressure.

Oxygen at pressure

Once the chamber has reached the desired pressure level all you need to do is breathe normally. 

If at anytime you feel uncomfortable you can communicate with the operators through the two-way intercom. 

Occasionally the chamber may have to be 'flushed' while this is quite noisy it is nothing to be worried about, it is only to make sure the air inside the chamber remains an appropriate mix. 

2

Decompression 

Your operator will let you know that the session is ending and that your air supply will be switching back to normal, just continue to breathe normally. 

It will become noisy, and a little cooler, in the chamber as the pressure is balanced and you may again have to equalise your ears. 

Decompression should take between 10 and 20 minutes.
