Hyperbaric O2 Therapy  

How does it work?

Hyperbaric Oxygen Therapy is a safe non-invasive therapy that uses an increase in atmospheric pressure to increase oxygen supply to cells and tissues. In physics Henry's law states that the amount of dissolved gas in a liquid is proportional to it's partial pressure above the liquid. At a greater pressure additional oxygen dissolves into the blood plasma and enters the tissues directly. This stimulates the body’s healing processes, increases stamina and endurance and helps the body reach a state of balance and wellbeing. 

How Does It Work?

Normally it is the red blood cells which distribute the majority of oxygen in your body, however with hyperbaric oxygen therapy the increased pressure forces oxygen into the body fluids, more oxygen is dissolved into the plasma greatly increasing the oxygen levels.  Oxygen is needed to complete the metabolic processes in each one of our cells.


Lets take a look at our blood flow -: 

This is what a normal well functioning capillary should look like where blood is being diffused into the tissues. 

Normal Blood Flow

Occluded Blood Flow


When we have an occlusion, only the plasma is able to get through the blockage so no red blood cells carrying oxygen are able to get to the damaged tissue. The tissue then begins to break down further due to lack of oxygen which is needed for repair.

Hyperbaric Oxygenation


100% oxygen under pressure diffuses from the plasma up to three times further into the tissues.

Regeneration - Neurovascular


More oxygen is forced into the tissues which encourages new blood vessels to form. Bringing more oxygenated blood to the tissues and forming new pathways. Neurovascular regeneration.

What Happens with Hyperbaric Oxygen Therapy -- 

When the oxygen-saturated plasma moves from the circulatory system into tissue spaces it penetrates areas where blood flow is diminished or compromised and carries oxygen molecules with it. Therefore more oxygen is delivered to more cells than can be delivered by haemoglobin.​​ Other body fluids, such as the cerebrospinal fluid, are also infused with molecular oxygen.

The body has now become hyperoxygenated.


  • The body can be saturated with up to ten times the normal amount of oxygen.


  • The amount of oxygen available to cells increases, which allows them to function beyond a "maintenance" status, or to be fired into a functioning state. Hyperoxygenated cells  perform at an optimal level with less energy expended.

  • Oxygen now effortlessly crosses the blood brain barrier providing the brain tissue with a source of readily available molecular oxygen. Cells are able to metabolize vital glucose, necessary for the production of neurotransmitters essential in brain function, without expending extra energy which would use vital nutrients. 

  • The availability of neurotransmitters increases.

  • The amount of stem cells within the body increases.

  • There is stimulation of growth for new capillaries (tiny blood vessels) which then allows circulation to be either improved or restored. This reduces or even eliminates hypoxia in affected areas. An increased network of blood vessels promotes deeper circulation of oxygen and nutrients under normal conditions.  Normal circulation allows certain medicines and antibiotics to penetrate farther into muscles and tissues which also helps to combat microorganism growth.


  • Collagen rich connective tissue cells are stimulated therefore new skin growth is promoted.


  • Molecular and enzymatic changes occur, and the ability of white cells to remove foreign bodies from the bloodstream increases such as bacteria, fungi, dead cells and waste by-products.


  • The process involved in the normal remodeling of normal bone is also stimulated.


  • Immune response is stimulated.


  • The result of all this is anti-inflammatory.


  • Swelling is reduced and mitigates damage to the surrounding cells, tissues and blood vessels, this is particularly important to brain injuries. Swelling reduction in the brain lowers intracranial pressure. It is therefore also a useful adjunct in treating body trauma and certain sports injuries.

  • Glutathione production increases by 15%.

  • The growth of some bacteria is inhibited and anaerobic organisms (non-oxygen tolerant) die off. For example those found in gas gangrene and certain Lyme spirochetes.  The performance of certain medications and antibiotics can then be enhanced. Superoxides, peroxides and other compounds formed in the presence of high oxygen tensions naturally destroy anaerobic bacteria. Many of the body’s bacterial defence mechanisms are oxygen dependent so when tissue partial pressure of oxygen drops too low, effective ingestion and killing by phagocytic leukocytes is hindered. Re-oxygenation of those tissues allows phagocytosis and other host defence mechanisms to return.


  • The clotting effect that results from return of blood flow to constricted areas is also reduced and platelets are disaggregated.

  • Carbon Monoxide damage is hindered or mitigated.


  • The elimination process is accelerated with the increase in pressure involved in hyperbaric oxygen therapy.

  • Hyperbaric oxygen acts as an alpha-adrenergic drug.


  • Edema following burns or crush injuries can be reduced by the vasoconstriction that occurs with HBOT. As extra oxygen is carried by the blood plasma so an increase in tissue oxygen delivery occurs with HBO.

  • The quantity of oxygen carried and transferred to ischemic tissue by the blood is increased. Increased oxygenation relieves the ischemia by promoting osteoclastic and osteoblastic activity, collagen matrix formation and the breakdown of many toxins. In order to heal there is an increased metabolic need which the ischemic tissue can meet due to the extra oxygen.


  • It has been shown that 40 sessions of HBO at 2 ATA  increases the circulating endothelial stem cells by 8 fold ( Endothelial stem cells are responsible for angiogenesis or formation of new blood vessels.) This can be very helpful in wound healing and repair.
