  • What is Hyperbaric Oxygen Therapy (HBOT)?
    • Hyperbaric Oxygen Therapy entails breathing 97% oxygen (versus 21% oxygen in normal air) through a mask or nasal cannula in a pressurised chamber so that the absorption of oxygen into tissues and cells is increased by up to 10x. There are many health and wellness associated with the increase of oxygen. It is a simple, non-invasive and painless treatment.

      It has long been known that healing many areas of the body cannot take place without appropriate oxygen levels in the tissue. In many cases, such as in circulatory problems, in non-healing wounds and in strokes, adequate oxygen cannot reach the damaged area and the body's natural healing ability is unable to function properly. Hyperbaric oxygen therapy can provide this needed extra oxygen naturally with minimal side effects. To learn more about these, click here.

  • How does Hyperbaric Oxygen Therapy (HBOT) work?
    • At normal pressure i.e. 1atm (sea level) the air we breathe is on average 21% oxygen, which is transported throughout the body by red blood cells. With HBOT, oxygen is dissolved, due to the increased pressure, into all of the body's fluids, and can be carried to areas where circulation is diminished or blocked. In this way, extra oxygen can reach all of the damaged tissues and the body can support its own healing process. The increased oxygen greatly enhances the ability of white blood cells to kill bacteria, reduces local swelling and allows new blood vessels to grow more rapidly into the affected areas. It therefore also provides a boost to the immune system.

  • What pressure do the chambers go to?
    • The chamber goes up to 50KPa or 1.5atm

  • How many people can use the chamber at once?
    • We currently only offer mono-chambers that are suitable for one user at a time

  • How long is each session?
    • Sessions are 30mins or 60mins (but can be extended for an incremental fee)

      Please arrive 10mins early for your session to allow time to complete the consent form and to run through any queries you may have.

      Please also allow an additional 5-10mins decompression time at the end of your session.

  • How do I pass my time inside the chamber?
    • During the session you may read a book, meditate, sleep, listen to music or just relax. Smartphones are permitted in the chamber, at your own risk. Eye masks and books are available to borrow for the duration of your session.

  • Is it claustrophobic?
    • The chambers are large enough to bend your knees, raise your arms and move around a little. They also feature an air conditioning unit and a large window so that you are able to look out into the room. Therefore most clients do not feel claustrophobic during their session unless they suffer from extreme claustrophobia. Eye masks are also available to patients if they wish to sleep during the session.

  • What do I need to wear?
    • There are no clothing restrictions for use of the hyperbaric oxygen chamber, but it is advisable to wear something loose and comfortable.

  • How will I feel after my session?
    • Most patients report feeling refreshed, energised, relaxed, “lighter” or in a better mood after their hyperbaric oxygen session.

  • How safe is Hyperbaric Oxygen Therapy?
    • As with any treatment, side effects are possible. They are however, minimal. HBOT has been proven to be extremely safe, and the actual number of side effects is very small. Oxygen under pressure (HBOT) is a therapeutic dose of oxygen. As with any treatment, the higher the dose (in this case oxygen) the greater the risk for potential side effects. The prescription dose of oxygen is based upon pressurisation, time, and %of O2. Therefore, an increase in pressurization, time, or %O2 will all independently increase the dose of oxygen. With short term 100% O2 delivery, the side effects noticed at 1.5atm and 2.2atm are relatively minimal compared to the side effects at 3.0atm or higher. At clinical pressure below 3.0atm clinicians have demonstrated a significant decrease in the incidence of initial onset oxygen toxicity. At The Wellness Lab, pressurisations do not exceed 1.5atm, and treatments are maintained at an hour in duration thus minimising the risk of potential O2 toxicity.

  • What are the possible side effects?
    • The most common side effect is discomfort to the ears and sinuses caused by pressure changes. As the chamber is being pressurized, air presses on your ear drums and pushes them inwards which may cause the same discomfort you might experience on a flight. If this is the case, please inform the operator using the intercom system in the chamber, and the operator will stop pressurizing and/ or decrease the pressure until you equalize. Once you’re comfortable they will resume pressurizing. We can show you techniques to promote adequate clearing of the ears during treatment. Decongestants may be helpful. This problem is temporary and resolves when HBO treatment is completed.

      Very rarely (and unlikely at 1.5atm), oxygen toxicity can cause CNS and pulmonary effects. Seizures occur very rarely during treatment and are self-limiting. Seizures will cease when the patient is removed from breathing the pure Oxygen. Factors such as history of seizures, high temperature, acidosis and low blood sugar should be taken into account before treatment is begun.

      Pulmonary Oxygen toxicity may occur in patients who require supplemental Oxygen between treatments. This is very rarely seen with the limited number of treatments currently used.

      Some patients may suffer Claustrophobia. This is managed by maintaining communication, use of relaxation techniques and mild sedation, If necessary. If you have a problem with this condition please let us know.

      Patients with cataracts may experience accelerated maturation of the cataract, but the treatments DO NOT cause cataract formation.

  • Are there any contraindications?
    • Hyperbaric oxygen therapy may not be suitable for you if you are experiencing any of the following:

      • A tension pneumothorax (a collapsed lung)
      • Upper respiratory infections, chronic sinusitis or sinus problems
      • High fever
      • Severe emphysema or other breathing problem
      • Pregnancy

      Additionally, doctor’s consent is required for the administration of hyperbaric oxygen in the presence of the following:

      • Asthma
      • Congenital spherocytosis
      • Cisplatinum
      • Disulphiram (Antabuse)
      • Doxorubicin (Adriamycin)
      • Emphysema with CO2 retention
      • History of middle ear surgery or disorders
      • History of seizures
      • Optic Neuritis
      • Pneumothorax
      • Upper respiratory tract infections
      • Viral infections

      If in doubt, please contact your doctor.
