FAQ

Key questions and answers about oxygen therapy.

What is hyperbaric therapy (HBOT)?

Hyperbaric therapy (HBOT) involves breathing pure oxygen in a special chamber under increased pressure. this increases the amount of oxygen that the blood can absorb, supporting the body's natural healing processes.

Is hyperbaric oxygen therapy safe?

Hyperbaric oxygen therapy is a tested and completely safe method of assisting treatment. It also causes no discomfort during its course due to its relatively low and completely non-invasive pressure (1.3 ATA).

The therapy is carried out under the supervision of a hyperbaric chamber operator. All risks will be discussed before the treatment starts.

How long does an oxygen therapy session in an oxygen chamber last?

The entire session lasts 75 minutes. During the first 10 minutes there is compression of the chamber and during the last 10 minutes there is decompression. During the oxygen therapy session you can relax, or read a book or listen to a podcast.

Are there age restrictions for oxygen therapy?

No, even children can benefit from oxygen therapy. In the case of patients under 6 years of age, the child enters the chamber with a guardian for psychological comfort. Hyperbaric therapy has shown positive effects in children with autism.You can read more about this under Indications -> Autism

Are there contraindications to the use of oxygen therapy?

Yes, there are contraindications that disqualify the possibility of starting oxygen therapy. They can be divided into 2 groups: contraindications that absolutely rule out the procedure and relative contraindications - in their case, approval for the therapy can be given by the doctor after a specialist consultation.

Absolute contraindications:

  • undrained pneumothorax,
  • bleomycin treatment (both current and past).


Relative contraindications:

  • upper respiratory tract infections,
  • Doxorubicin treatment (up to 24 h after the last dose),
  • seizures (also episodic),
  • treatment with disulfiram (used to treat alcoholism),
  • Cis-platin treatment
  • high temperature (fever),
  • history of pneumothorax,
  • thoracic and respiratory surgery
  • optic neuritis - even if it was a long time ago
  • malignant tumours
  • pregnancy
  • pacemaker - except for models with a certificate confirming safe operation of the pacemaker under increased pressure
  • lung diseases with CO2 retention (emphysema, COPD)


If you are in doubt as to whether any of these conditions are a contraindication to hyperbaric chamber therapy, please discuss the matter with your doctor. It is worth remembering that although hyperbaric chamber oxygen therapy is a non-invasive treatment, it may have minor side effects in the form of fatigue and headaches. Particularly after the first and second sessions.

Are there any side effects?

The only side effects that occasionally occur in some patients are discomfort in the ears, a feeling of them being 'plugged' and noise, which is caused by the higher pressure in the chamber. The same happens for passengers during take-off and/or landing of an aircraft. They usually resolve spontaneously and sometimes require swallowing saliva and light massage of the ear area.

What is the admission procedure for an oxygen therapy session?

The first step is to complete a questionnaire. Based on this, we will interview you about your current state of health and any ailments. This is an essential procedure for your safety - it will help detect potential contraindications to the procedure.

How to prepare for a session in a hyperbaric chamber?

Pre-session:

  • Do not consume alcohol up to 12 hours before the treatment and do not smoke cigarettes up to 2 hours before the treatment. Smoking cessation is recommended to maximise the effects of the treatment.
  • Avoid perfumes, make-up, hairspray and any ointments or creams.
  • If you have dressings on your body on the day of the procedure, these must not contain fat-based preparations (ointments, creams).
  • Before your session in the chamber, you must use the toilet, as you cannot leave the chamber during the treatment, plus the therapy has a diuretic effect.
  • In relation to the earlier point, you should also not consume fizzy drinks just before the session.
  • If you have an upper respiratory tract infection, this information should be reported to staff.
  • Dress comfortably, comfortably. You can take an item into the chamber with you to pass the time - it could be a book, your favourite podcast, etc. :)
Can children benefit from oxygen therapy?

YES, there is no minimum age limit for oxygen therapy users. In the case of children under 6 years of age, for the child's psychological comfort, the child enters the chamber with a guardian.

How many people can stay in the chamber?

One person is allowed in the chamber. The exception is children under 6 years of age, who can attend an oxygen therapy session together with an adult.

How does a hyperbaric therapy session work?

The session consists of several stages:

  • compression - increasing the pressure in the chamber to a certain value
  • patient breathes pure oxygen through a mask
  • periodic interruptions in breathing oxygen
  • decompression - gradual depressurisation
How does hyperbaric therapy feel?
During therapy, you may feel a fullness in your ears similar to the pressure changes during an aeroplane flight. most patients find the sessions relaxing.
How many sessions will I need and how often?
The number and frequency of sessions depends on the specific condition. Some require five visits, others may need daily sessions for 20-30 days.
How quickly can you see the effects of the chamber?
This is very individual - it is usually possible to tell after just 3-4 sessions whether oxygen therapy is working as the client expects. Sometimes the effects can be felt after only 2-3 sessions.
