How does hyperbaric oxygen therapy (HBOT) promote healing?

Your body needs an adequate supply of oxygen to function, and even more oxygen to help injuries heal. The oxygen rich environment in the hyperbaric oxygen chamber is two to three times higher than normal air pressure at sea level. This means that the oxygen level in your blood stream increases up to five times more than would be possible if you were breathing pure oxygen at normal air pressure.

The increased oxygen helps to fight bacteria, optimise the effectiveness of antibiotics, reduce swelling, improve the functioning of the immune system, and promote the release stem cells and growth factors. All of these stimulate healing of compromised skin, tissues and bone starved of oxygen.

How is HBOT provided to patients?

Depending on its size, a hyperbaric oxygen chamber can accommodate one or more patients. Once patients are inside the chamber, it is gradually pressurised to the required level. In some chambers, patients wear a clear hood filled with pure oxygen. During the session, it is common to feel some pressure in your ears, which can be relieved by equalising as with air travel.

How is HBOT provided to patients?

The number of sessions required is determined by the patient’s specific condition. A session typically lasts an hour or more. Electronic devices are not allowed inside the chamber, but patients can read books or magazines.

Every treatment is supervised throughout by a qualified attendant and safely controlled by a trained operator. The treatment is overseen by an on-site hyperbaric doctor. The care team will also do various checks after the therapy.

Distinct differences between hyperbaric oxygen therapy (HBOT) and lower air pressure therapy (mHBOT)

Lower pressure air therapy – sometimes referred to as mHBOT – is increasingly being offered to the public. It is important to note that there are distinct differences between air pressure therapy and the treatment offered at hyperbaric oxygen therapy units certified by the Southern African Undersea and Hyperbaric Medical Association (SAUHMA).
