Hyperbaric Oxygen Therapy (HBOT)
Introduction to Hyperbaric Oxygen Therapy
We all have to-do lists. Things we need to fix. Things we need to get done. In the same way, our bodies also have a to-do list. The body is constantly making new cells, repairing damage caused by germs and toxins, balancing hormone and chemical levels, and generally doing everything it can to keep you happy and healthy
But when our bodies don’t have the resources they need to complete all of these tasks, and when toxins or injuries or pathogens cause our to-do list to get longer and longer, disease and disability will begin to occur. And we can quickly go from happy and healthy to unhappy and unhealthy. In order to give the body more resources to heal and recover, there are many good nutrients that we can make sure we are getting by changing our diet and supplementing if necessary.
However, do you know which nutrient is most important of all? The answer is O2, or oxygen.
More than any food… more than even water itself… oxygen is the one nutrient that your body needs more than all others. Usually we don’t think of oxygen as a nutrient, but in reality, it is the most fundamental nutrient that we need for healing and for life itself.
So, how does hyperbaric oxygen help the body heal itself? The short answer is that hyperbaric oxygen gives the body more resources to do all the things on its to-do list. Hyperbaric Oxygen has been shown to:
- Destroy harmful bacteria
- Decrease inflammation
- Produce new collagen
- Increase white blood cells
- Regenerate bone
- Stimulate capillary growth
- Strengthen the immune system
- Help mitochondrial function
And perhaps most amazing of all, it even creates new stem cells in the body. After 40 sessions of hyperbaric oxygen, stem cell production increases all the way to 800%. Your body turns these stem cells into whatever cells that it needs, facilitating healing rapidly and naturally.

What is Hyperbaric Oxygen Therapy?
Hyperbaric Oxygen Therapy, HBOT, is a specialized form of medical treatment administered by delivering 100% pure oxygen to the body through increased atmospheric pressure greater than 1.3 ATA. in an enclosed hard chamber.
How it Works
Hyperbaric Oxygenation Breathing 100% oxygen under pressure causes the oxygen to diffuse into the blood plasma. This oxygen-rich plasma is able to travel past the restriction, diffusing up to 4 times further into the tissue. The pressurised environment helps to reduce swelling and discomfort, while providing the body with at least 10 times its normal supply of oxygen to help repair tissue damaged by the original occlusion or subsequent hypoxic condition.
Blood Vessel Regeneration
Blood Vessel Regeneration Hyperbaric Oxygen Therapy (HBOT) forces more oxygen into the tissue, encouraging the formation of new blood vessels. As these new blood vessels develop, the red blood cells start to flow, delivering even more oxygen to the affected area. This creates the optimal environment for the body’s natural healing processes to repair damaged tissue.
Normal Blood Flow
Normal Blood Flow There is 21% oxygen in the air that we breathe, and our lungs transfer this oxygen to our red blood cells (via haemoglobin). These oxygen-filled red blood cells are carried around the body by the plasma (fluid), which travels through the blood vessels. The oxygen diffuses into the surrounding tissue ensuring that it is delivered to where it is needed most.
Restricted Blood Flow
Restricted Blood Flow When there is a restriction (occlusion) in blood flow due to surgery, illness, or injury, the red blood cells block the blood vessel and are unable to transfer oxygen to the cells on the other side of the occlusion. This causes swelling and starves the area of oxygen, causing hypoxia (a lack of oxygen), when this occurs the tissue begins to break down.
At pressures greater than normal, the body is able to incorporate more oxygen into blood cells, blood plasma, cerebral-spinal fluid and other bodily fluids. The increased oxygen absorption experienced during hyperbaric oxygen therapy significantly enhances the body’s ability to aid in its own healing.
Once a person is in the increased atmospheric pressure the body responds by reducing inflammation. With the inflammation reduced the blood flow increases the delivery of oxygen to oxygen deprived areas.
It’s at this point that the healing process is accelerated.
The body’s natural healing mechanisms can now function efficiently because the damaged tissues are receiving more oxygen. Even when the blood supply has been compromised, tissues can still receive the healing benefits of oxygen from other body fluids and plasma in the surrounding area.
The History of HBOT
HBOT is not new.
In fact, the concept of Hyperbaric Medicine has been around since the 1800’s. Since then, hyperbaric oxygen therapy has been used around the world to successfully treat a wide variety of medical conditions.
In 1937 hyperbaric oxygen treatments were first used for decompression sickness but it was not until 1956 that interest in hyperbaric medicine really heated up. In Amsterdam that year, Dr. I Boerema reported that hyperbaric oxygen (HBO) was a therapeutic aid in cardiopulmonary surgery. Shortly after his colleague’s discovery, W.H. Brummelkamp, published a discovery of his own: anaerobic infections were inhibited by hyperbaric therapy.
International interest was rekindled when in 1962, reports of the enormous benefits of HBOT in the treatment of carbon monoxide poisoning were published. These discoveries and more, pushed hyperbaric medicine into the modern era. Installations of hyperbaric units quickly began at some of the most revered and prestigious medical centers in the United States. A few of these early adopters were Harvard Children’s Hospital, New York Sinai Hospital, Duke University, and Good Samaritan Hospital in Los Angeles.
Fast-forward to modern HBOT
The advent of modern imaging technologies such as Magnetic Resonance Imaging (MRI) and Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) , have provided researchers unprecedented insights into the actions and mechanisms of hyperbaric oxygenation and its effect on tissue. It’s no coincidence that the most significant, documented advancements in Hyperbaric Medicine have emerged recently in large part due to pre- and post- hyperbaric therapy evaluation using these high-tech tools.
As hyperbaric research continues, scientists are finding that neurological conditions, stroke and brain injuries, all previously considered to have poor prognoses, respond well to HBOT.
Successful treatment with hyperbaric for conditions as diverse as autism, fibromyalgia, multiple sclerosis, side-effects of chemotherapy and radiation toxicity in cancer patients have growing numbers of researchers, physicians, patients and their families believing in the power and efficacy of HBOT.
21 Reasons Why
1. HBOT significantly reduces swelling
Local vasodilation (when blood vessels in the body become wider) following damage to tissue increases blood flow and together with an increase in vascular permeability (the movement of fluids and molecules in and out of blood vessels), increases extravascular (outside blood vessels) proteins, fluid and produces swelling. This swelling contributes to the pain felt. As the oxygen supply reduces, blood flow increases which will only serve to exacerbate the swelling following injury and impede the inflammatory process that assists the commencement of healing. Hyperbaric oxygen therapy reduces vascular vasodilation and permeability by increasing the oxygen content within the blood.
2. HBOT significantly reduces edema
The development of oedema (accumulation of excess lymph fluid) and swelling is caused by a number of factors such as an increase in local blood flow and also damage to local blood and lymphatic vessels. The pressure exerted by swelling and oedema on surrounding structures can compromise circulation. When this pressure in the surrounding tissues approaches or exceeds that in the blood vessels, then blood flow will slow or cease altogether. Oedema and swelling also contribute to tissue hypoxia (a shortage of oxygen in the body) by increasing the distance between the capillary (smallest blood vessels) and the cells, which impedes cell function, metabolism and the inflammatory process by increasing the diffusion (movement of particles from an area of high concentration to an area of low concentration) distance. Hyperbaric oxygen therapy is able to combat the increased distance for oxygen diffusion from blood vessel to cells by increasing the oxygen content within the blood which will result in an increased oxygen delivery to cells and tissues forced further away from the blood vessels due to swelling and oedema, shortening the inflammatory process, thereby speeding the healing and repair of tissues.
3. HBOT significantly shortens the inflammatory process
The body’s initial response to any injury involves inflammation and attempted repair. Inflammation is the process by which cells such as phagocytes (white blood cells) gain access to the damaged/injured tissues and cells in order to prevent infection and enable healing to commence. Decreased oxygen supply impacts greatly upon the inflammatory process as the cells involved in inflammation are oxygen dependent. Should oxygen supply be decreased, this will greatly impair and slow the inflammatory process and healing. Increased oxygen availability promotes vasoconstriction (when blood vessels in the body become thinner) and this causes tissue fluid reabsorption and helps reduce oedema and swelling whilst keeping the tissue well oxygenated due to the high oxygen content within the blood. Hence supporting the cells of the inflammatory process to remove cell debris and micro-organisms impeding infection.
4. HBOT improves range of motion
Following hyperbaric oxygen therapy, range of motion is improved and returned more rapidly as the inflammatory process is accelerated. Swelling and oedema are also decreased and resolved more rapidly. As a result, pain will be less allowing for the return of range of motion as the healing process gains momentum.
5. HBOT increases the production of collagen
Following the initial healing process of the inflammatory response and the prevention or removal of infection, comes the next chapter in tissue/wound healing. Collagen is the connective tissue developed and laid down by fibroblasts, the repair cells of the body. Collagen acts as a base layer in the healing wound and assists the wound to close and repair. The formation of collagen and hence wound healing/recovery is highly dependent on the presence of adequate amounts of oxygen. The actual production of collagen by fibroblasts is also extremely dependent on oxygen availability. As hyperbaric oxygen therapy markedly increases the oxygen available within the blood this in turn enables fibroblasts to produce increased amounts of collagen required for healing of wounds and tissue damage.
6. HBOT increases growth of cells that form reparative tissue (Fibroblastic proliferation)
Clinical research has demonstrated that a number of days following injury there occurs a migration of fibroblasts (connective tissue cells responsible for collagen production) into the area of damage. These cells then divide and replicate producing large amounts of collagen (connective tissue used to repair damage to tissue) that acts as the building block for the healing of tissue and wounds. The development and migration of fibroblasts is assisted by the influx of oxygen resulting from hyperbaric oxygen therapy, this then supports the development and action of these particular cells which play a vital part in the healing/recovery process.
7. HBOT supports scar tissue rehabilitation
A decrease in oxygen available to cells such as fibroblasts impairs their action, impacting upon the healing of tissue, causing healing to take longer, and inhibiting the quality of scar tissue developed or rehabilitated, which in turn greatly decreases tissue strength. Healing occurs both faster and stronger in wounds/injuries that are treated with hyperbaric oxygen therapy due to the demands of oxygen availability by the cells and tissues responsible for the healing process being met.
8. HBOT promotes greater tissue strength
As the oxygen concentration of the blood increases during hyperbaric oxygen therapy, cells further from blood vessels are more adequately oxygenated. Hyperbaric oxygen therapy allows for increased oxygen availability in more extensive areas enabling fibroblasts to carry out their part of the healing process for tissue damage and injury, more rapidly covering larger areas. Hyperbaric oxygen therapy saturates the blood plasma with oxygen, this in turn reaches the areas of damage/injury with greater efficiency than red blood cells, providing all cells and tissues with the much needed agent for healing, oxygen. The cells responsible for the development of scar tissue for healing are then able to carry this out more rapidly and the resulting tissue integrity is stronger.
9. HBOT enhances the growth of new blood vessels (Angiogenesis)
Injury or damage to tissues also results in damage and destruction of the supporting blood vessel structures. The healing process is reliant on these structures for supply of the blood containing the cells and nutrients that carry out and enable healing as well as the removal of damaged cells, debris and foreign micro-organisms. Research has demonstrated that treatment with hyperbaric oxygen therapy significantly increases the number and actual size of blood vessels in damaged tissues and wounds. This allows the healing process to occur faster speeding the recovery of the injury or wound.
10. HBOT increases oxygen levels in tissues (Hyperoxia)
With an increase in oxygen availability resulting from both blood that is highly saturated in oxygen dissolved in the plasma, and an increase in the number of blood vessels due to new vessels being created as well as the healing of damaged blood vessels, tissues and cells become highly saturated in oxygen.
11. HBOT increases oxygen perfusion area around wounds
Oxygen perfusion around wounds and damaged tissues is greatly increased when the blood supply to these areas possesses greater than normal levels of oxygen within blood plasma as well as carried on red blood cells. The oxygen contained in the blood plasma is more easily accessible than that carried to the tissues and cells of the wound/damaged area on red blood cells, and this method of oxygen supply is less labour intensive and energy taxing. The cells involved in the healing process are highly dependent on oxygen to carry out their healing function and this increased demand for oxygen in the area around wounds by the increased number of healing cells in that location is met by the increased oxygen saturation of the blood following hyperbaric oxygen therapy.
12. HBOT stimulates new capillary growth
During the time of injury and damage the microcirculation and the blood vessels of this circulation (capillaries) are vital to the healing process through the supply of nutrients and oxygen and the removal of waste and debris to enable the cells responsible for healing to successfully complete their function. Growth of new, and repair of damaged capillaries are stimulated within the damaged tissues by hyperbaric oxygen therapy, providing increased oxygen availability to these areas. The increased oxygen supply and increased pressure employed by hyperbaric oxygen supply are both responsible for the stimulation of new capillary growth and the repair of existing capillaries.
13. HBOT improves the survival of tissues in the ‘grey area’ of crush injuries
The ‘grey area’ of crush injuries can be defined as the area between the tissues that are obviously irreversibly damaged and those tissues that are undamaged. The tissues of the ‘grey area’ benefit greatly from increased oxygen supply, improved circulation and blood supply. These are the aspects that will allow the tissues of the ‘grey area’ to be saved, salvaged and repaired. Hyperbaric oxygen therapy has been shown to support and maintain tissue oxygenation within the ‘grey area’ resulting in a better outcome for the tissues, wound or injury.
14. HBOT increases production and improves the action of Osteoblasts and Osteoclasts
Osteoblasts are the cells responsible for bone formation and osteoclasts are the cells responsible for bone reabsorption. Both these cells work together to form bones and control the amount of bone tissue. The provision of increased levels of oxygen allows for increased production of these cells and enables them to conduct bone repair and formation more adequately through the reduction of oedema and growth of new blood vessels in the micro-circulation.
15. HBOT improves bone regeneration for faster recovery
When the inflammatory process, swelling and oedema is rectified more rapidly the repair and regeneration of bone is able to commence sooner. With the increase in blood supply and oxygen availability, the tissues and cells responsible for bone regeneration are able to carry out their task of healing more efficiently, resulting in accelerated recovery and a better result in the healing tissues.
16. HBOT helps prevent infection
Research has demonstrated that having lower oxygen levels in tissues and wounds increases the possibility of infection. Changes in wound and tissue oxygenation impacts greatly upon the wound immune mechanism. Having an improved or increased tissue oxygen supply reduces the incidence of wound infection as the cells responsible for prevention and recovery from infection are dependent on oxygen, therefore additional oxygen benefits the healing process.
17. HBOT increases white blood cell production
The major players in the bodies immune response are the white blood cells. Providing the body with increased oxygen availability increases the production of white blood cells providing benefit to the bodies immune response. High-dose oxygen delivered under pressures greater than sea level (hyperbaric oxygen therapy), stimulates and enables the bodies immune response.
18. HBOT enhances ability of white blood cells to remove bacteria and debris (Leukocyte activity)
Without oxygen or in a hypoxic (shortage of oxygen in the body) environment the function of white blood cells becomes diminished. This in turn provides a significant threat of infection as the bodies immune response is impaired. The increased oxygen supply offered by hyperbaric oxygen therapy assists in bacterial killing through improving leukocyte (type of white blood cell) function.
19. HBOT potentiates the use of antibiotics
Research has demonstrated that periods of hyperoxia (increased oxygen levels in tissues) and hyperbaric oxygen therapy has influenced the activity of some antibiotics, enhancing their effectiveness. This enables the presenting infection to resolve quicker.
20. HBOT destroys harmful bacteria (Antimicrobial effect)
Hyperbaric oxygen therapy provides direct bactericidal (substance that kills bacteria) and bacteriostatic (hampers the growth of bacteria) effects against bacteria due to the generation of oxygen free radicals. These free radicals are able to damage the membranes and make up of the bacteria rendering them ineffective or killing them. Anaerobic (without oxygen) organisms find an increased oxygen environment toxic and are unable to survive.
21. HBOT reduces surgery complications for smoker
Research has proven that the use of tobacco and smoking causes arterial vasoconstriction (narrowing of the arteries). This leads to numerous health issues as blood flow becomes impaired, affecting the cells and tissues of the body. When the bodies blood flow is impaired as a result of conditions such as arterial vasoconstriction, oxygenation of the cells and tissues is greatly impaired as the oxygen carrying components of the blood (red blood cells) are unable to fulfil the oxygen requirements for cells and tissues. Hyperbaric oxygen therapy increases the oxygen levels within the blood plasma and this element is able to travel to the cells and tissues with greater ease and success providing the much needed oxygen. Smokers’ recovery and complications from surgery can be greatly diminished by the use of hyperbaric oxygen therapy as the cells and tissues continue to have their oxygen requirements met and often exceeded. This enables the healing process to be improved and accelerated.
What Makes Oxford's Chambers Different?
At Oxford Hyeprbarics our Seichrist Chambers are able to generate 3 ATA of pressure and typical treatment protocols are between 2.0ATA and 2.4ATA. So, at 3.0ATA (3.0ATA x 760mmHg x 100%=2,280mmHg) we can deliver almost ten times the amount of medical grade oxygen to you. At our typical treatment depths we generate 1,520 mmHg of pressure at 2 ATA (almost 7 times as much oxygen) and 1,824mmHg at 2.4ATA (almost 8 times as much oxygen as an inflatable bag.
Oxford Hyperbarics also finds it very important to treat at a research validated protocol. All valid scientific studies demonstrating the benefit of hyperbaric therapy were performed at pressures higher than those able to be achieved in an inflatable bag. You cannot apply those benefits at the much lower pressures from inflatable bags.
The FDA does not recognize inflatable bags as a medical device for hyperbaric oxygen treatment. You will never find them in any reputable hospital or medical office. The FDA only recognizes inflatable bags as a device used to treat altitude sickness during transport to a definitive medical facility. Scientific literature shows that oxygen becomes bacteriostatic (biological or chemical agent that prevents bacteria from reproducing) at 1.5 ATA. Since inflatable bags can only produce 1.3ATA they not only can’t prevent bacteria from growing, they can actually enhance the growth of some molds, fungus, and aerobic bacteria!
Parents and patients are also being informed that they can attach an Oxygen concentrator to the mild HBO to increase Oxygen delivery to the bag’s occupants. This is an immediate concern as the risk of fire is significantly elevated when parents indicate that they are also using computer games and DVDs inside the ‘chamber’ to keep the child entertained. This is completely inappropriate and may well end up with somebody being severely burnt or losing their life! The additional use of Oxygen concentrators and internal use of electronic devices are in direct conflict with manufacturer’s recommendations notwithstanding the USA FDA product standards. Similar standards exist in Australia.
Many of the mild chamber manufacture’s websites makes a deliberate attempt to embrace a range of medical conditions and disorders under the banner of ‘hyperbaric therapy’. The public are ‘none the wiser’. However the evidence supporting the use of Hyperbaric Oxygenation in these conditions and disorders are on the basis of applications using 100% Oxygen at pressures typically 1.75-2.5 ATA or greater. Hyperbaric oxygen therapy is about saturating the body with oxygen. This is most effectively done by delivering 100 percent oxygen through two different pathways: by inhalation through your airways and by absorption through your skin.
It is important to note the difference between Hyperbaric Oxygen Therapy (HBOT) and Hyperbaric Therapy (HBT) also referred to as Mild Hyperbaric. Most mild chambers are inflatable bags originally intended for use in mountain climbing accidents or air sickness and have been substituted for pressurized oxygen therapy. The most significant difference between the two is the “O” as in oxygen. Because Mild chambers do not use 100 percent pure medical grade oxygen it technically cannot be referred to as Hyperbaric Oxygen Therapy and cannot equally be compared to the potency and effectiveness of Hyperbaric Oxygen Therapy.
The bottom line, not all “hyperbarics” are created equal. Do your research, look at the Peer Reviewed research that is out there, think about what makes sense, and think safety first.
When looking for a provider of hyperbaric oxygen therapy inquire about the chambers they use, age of chambers, service records, oxygen provider, do they require a mask or hood, and are their CHT’s on staff and someone who has gone through the Safety Director course.

Hard vs. Soft chambersHyperbaric Oxygen Therapy or “Mild” Hyperbaric Therapy “Can’t I just buy a chamber and put it into my home?”
The question is not can you, but is it safe and effective. First of all, you cannot legally put a real hyperbaric oxygen therapy chamber into your home. In addition to the National Fire Protection Association (NFPA-99) regulations and the illegality of medical-grade oxygen purchase, it just would not be safe.
What can you legally put into your home? (This is in the US; Canada does not allow even mild hyperbarics in the home.) The question about what is the difference between hard-sided medical grade hyperbaric oxygen chambers and inflatable hyperbaric chambers (mild/soft hyperbarics) is a common asked question. At the Oxford Recovery Center, we use only hard-sided Sechrist chambers. If inflatable bags were an effective treatment modality it would only make sense for us to use them, as the cost would be immensely less expensive for the chamber cost, oxygen (tank, plumbing, corral, and gas), not to mention the extensive NFPA-99 regulations for the build-out. However, hyperbaric oxygen therapy is NOT the same as the mild hyperbarics.
To compare the differences, let’s look at the oxygen in the blood. We measure the changes from arterial blood gases. Arterial oxygen at 2.4 ata 100% oxygen is 1,824 mmHg (normal air pressure is 157mmHg). This refers to how much oxygen is getting into the body, what is making the changes. Compared to using mild/soft chambers, the arterial oxygen at 1.3 ata 24% oxygen is 230 mmHg (normal air pressure is 157mmHg).Now Consider this: If you have a non-rebreather oxygen mask hooked up to an oxygen tank (the oxygen mask you see paramedics use when transporting a patient), the mask can deliver about 55% oxygen. The percentage is used by using the conversion equation (1ATA x 760mmHg x0.55=418mmHg). The moral of the story is that an oxygen mask can deliver a higher amount of oxygen than an inflatable bag so why would you expose yourself to the time and expense for such little benefit.
Let’s examine the reasons why we do NOT use inflatable bags and we do NOT call them hyperbaric oxygen chambers. For a quick comparison:
|100% medical grade oxygen||Ambient air (approximately 21% oxygen—mostly nitrogen)|
|Pressurized typically to a max of 3.0 ATA or depth of 66 feet (Some go to 6.0 ATA or 165 feet)||Pressurized to a max of 1.3 ATA or depth of 8 feet|
|Regrow bone and tissue in severely damaged areas of the body||Cannot regrow bone and tissue|
|Supported by thousands of clinical studies which validate successful healing||No such correlation has been made with soft chambers and healing|
|Many treatments are recognized for reimbursement by insurance companies and federal government||No conditions are reimbursed by insurance companies using soft/mild chambers|
|Designed to go to therapeutic pressures to achieve healing||Designed to temporarily treat divers and mountain climbers in route to a hard chamber|
|Kills harmful bacteria||Can promote the undesirable growth of aerobic bacteria|
|Meets the American Society of Mechanical Engineers, Pressure Vessels for Human Occupancy (“ASME PVHO-1”) standard||Does not meet the “ASME PVHO-1” standard|
|Loss of electrical power has no effect on pressure and oxygen flow||Loss of electrical power and chamber rapidly deflates causing possible barotrauma to patient’s ears and pneumothorax to patient’s lungs|
|No risk of contaminated or polluted air. A closed system of oxygen is piped in directly from a liquid oxygen tank. The liquid oxygen is converted to a gas on-site and pumpled directly into the individual chamber. There is no outside air contamination.||Risk of breathing contaminated or polluted air which can be counterproductive|
|Designed to heal ischemic tissue or tissue that is restricted from receiving enough oxygen by hyper-oxygenating the body, blood and plasma||No research shows healing ischemic tissue|
|Research shows a total of 40 treatments||Some results may be obtained in the lower pressure air filled chambers, however it will take many, many more sessions and the results often do not hold, or create issues with yeast or bacteria growth|
|Designed to use enriched gases like 100% oxygen||Never designed to be used with enriched gases like 100% oxygen|
|Arterial oxygen at 2.4 ata 100% oxygen is 1,824 mmHg (normal air pressure is 157mmHg). This refers to how much oxygen is getting into the body, what is making the changes.||Arterial oxygen at 1.3 ata 24% oxygen is 230 mmHg (normal air pressure is 157mmHg).|
