What is Hyperbaric Oxygen Therapy?

Each treatment is called a “dive” and during the dive, the high concentration of oxygen in the chamber allows you to breathe in oxygen at 90-95% concentration (compared to around 21% in normal air). The pressure combined with the levels of oxygen mean your body will absorb up to 1000% of your daily oxygen dependant on session length and pressure of chamber.

Your blood carries the extra oxygen through your body in the plasma, accelerating your natural healing process, helping to reduce inflammation, boosting the production of white blood cells that fight infection and speeding up recovery.

Oxygen makes up approx 65% of the human body and acts as an energy source for cells. Many factors such as stress, lifestyle and some unavoidable medical conditions can create low saturation of oxygen and it can turn into hypoxia. Hyperbaric oxygen therapy is a proven remedy for meeting the oxygen deficiency of the human body. A higher amount of oxygen dose in a sophisticated environment can help in supporting health issue allowing the body to recover faster.

Simply Oxygen do not recommend that HBOT be used as a replacement for conventional medicine, however it has proved to be a valuable form of complementary medicine for existing health conditions. Simply Oxygen recommends consulting your GP for a diagnosis prior to any treatment.

"We need oxygen to thrive not just survive"

We use oxygen to release energy from our body’s batteries called Mitochondria, this energy is not just used to function
(move, talk etc) but also to heal the body. Often when we have a lack of oxygen the following things will happen to our body.

Can assist with the healing of chronic illnesses, enhance general health and well-being and help to optimise sporting performances.

There is growing scientific evidence from around the world showing the potential benefits of hyperbaric oxygen therapy.

We are actively involved in this research with St Mary’s University currently looking at both HBOT and its use to  speed up recovery from Long covid as well as looking at its use to help with reducing the inflammation caused by concussion in sports such as rugby.

To showcase HBOT in a way that is equivalent to what pharmaceutical companies have to do with new drugs we are  running randomised blind control studies to be able to clearly show and talk about the benefits of Hyperbaric Oxygen Therapy.

Below we have highlighted research and trials from around the globe highlighting some of the fields that HBOT can be used to support recovery. Please note that whilst many of these conditions have had trials and research completed, in the most these trials are not large randomised control studies.


This will be dependant on the treatment plan that is prescribed for you post consultation with one of the team, however as a rule of thumb, sessions are 30 mins, 60 mins or 90 mins and the most common duration is 60 minute per session at full pressure however all sessions also include a pressurisation and depressurisation time of approx. 12-14 mins.

For an average 60 minute session you should expect to be with us for approx 1 hr 15 minutes.

For more details please contact us today on 03301-334757 or email us at info@simplyoxygen.co.uk

This will be dependant on what you have come in looking for support with. Our expert team will assess your needs and come back to you with an optimal plan for supporting your requirements, what number of sessions and at what frequency would be optimal for yourself.

We do not advise anyone who is pregnant to undergo hyperbaric oxygen therapy.

Hyperbaric oxygen therapy is generally considered to be extremely safe and is usually well tolerated with few side effects. While uncommon risks of the treatment include:

  • Oxygen toxicity
  • Congestion and pressure of the sinus and ear
  • Temporary near sightedness
  • Middle ear injuries / barotrauma of the ear
  • Claustrophobia


To ensure the risks are minimal at Simply Oxygen we have high levels of training for staff, extremely clear guidelines on usage of chambers for home use and an exemplary safety record.

Yes, children as young as 6 months can use HBOT, please speak to our team about this, in some circumstances parents / guardians will be required to do the treatment with the child (this is age dependant).

Some of our customers will relax and rest their eyes, whilst some meditate or do breathing exercises, you can also listen to music, audio books or a podcast, at the end of the day the choice is yours.

No, the majority of our customers find the experience to be relaxing and enjoyable. On pressurisation and depressurisation, you will experience ear equalisation the same as being at altitude in the mountains or taking off or landing in a plane. Should you feel pressure that is uncomfortable that you cannot clear yourself then our operators will help you clear the pressure by manually reducing pressure so that your session is enjoyable and comfortable.

This will depend on what you have come in looking for support with, once you have spoken to one of the consultation team they will give you and indication of how many sessions and how often you would need to come in.

HBOT is a safe and non-invasive treatment with very few side effects or contraindications. The risks will be discussed with you prior to treatment and prior to you reviewing and signing our consent forms.

Yes HBOT is covered by some insurers for some conditions however at present in the UK not that many, please refer back to your insurance company directly to see if they will be willing to cover this.

Our advice is to wear light cotton clothing avoiding cosmetics, perfumes, hair spray / deodorants and jewellery. Pre and post treatment it is not advised to have alcohol in your system and it is also advised not to have nicotine or caffeine as both of these cause constriction of blood vessels which may reduce the effectiveness of the treatment.


Simply Oxygen do not recommend that HBOT be used as a replacement for conventional medicine and note that it is not provided for the purpose of treatment of disease, disorder, or injury, but as a complementary treatment to alleviate a range of symptoms and support for recovery and wellbeing.

Individuals should always consult with their own GP about treatment option as well as risks and benefits of hyperbaric oxygen therapy as HBOT may not be appropriate for every individual and their specific condition. Individual results may vary and there are no guarantees of outcome.
