What is Hyperbaric Oxygen Therapy?
Hyperbaric oxygen therapy, or HBOT, is a medical treatment in which pure oxygen is inhaled, in a total body chamber while atmospheric pressure is increased. The Food and Drug Administration (FDA) has approved hyperbaric oxygen therapy for treatment of 13 conditions, including stroke, burns, and carbon monoxide poisoning. These uses for HBOT are covered by insurance and recognized by the medical establishment.1
Recently, medical research (including several double blind studies) points to hyperbaric oxygen therapy as a coveted neuro-therapeutic method for brain repair, which may be good news for those suffering from autism, post traumatic stress disorder (PTSD), traumatic brain injury (TBI), cerebral palsy, multiple sclerosis, chronic fatigue syndrome, migraine headaches, metabolic disorders (which can lead to dementia and Alzheimer’s), as well as other neurological disease, impairment, or dysfunction.2 Despite such studies, the medical establishment seems to remain skeptical of the efficacy of HBOT in such “off label” uses. Due to overwhelming anecdotal evidence however, numerous doctors are beginning to see the efficacy of HBOT, and have begun to take it seriously, and give it a chance.
In a recent ESPN article on football, concussion, and TBI, Dr. Lee Fox of Jupiter Medical Center said that he wondered if HBOT could help the brain recover from long-term trauma. “A head injury is really just a wound of the brain,” according to Fox, “Why wouldn’t it work on a different type of wound?” Fox has eloquently summed up my personal view as well.
How Does Hyperbaric Oxygen Therapy Work?
HBOT is believed to jump start the body’s own healing processes by forcing oxygen deep into the tissues. During HBOT treatment the patient is placed in an enclosed pressurized environment while breathing 100% oxygen (ambient air contains 20% oxygen). The complementary components of this process (pressure and oxygen) transpire simultaneously, and work synergistically. The tissues are saturated with pure oxygen, and the pressurization of the chamber forces the oxygen deep into the tissue. This process pushes oxygen beyond the hemoglobin (red blood cells that carry oxygen) and into the blood plasma and interstitial fluid, (fluid between the cells)3 reaching tissue that has been traumatized and damaged by hypoxia.
Patients in medical grade chambers typically “dive” to 7.5 PSI (pounds per square inch) and 1.5 ATA (atmospheres absolute), for 60 minutes at the prescribed pressure, though more severe injuries may require a longer HBOT session, i.e., more time inhaling oxygen under pressure, and may require treatment at a greater ATA.
Types of Hyperbaric Oxygen Therapy Treatment Chambers
There are three types of chambers for Hyperbaric Oxygen Therapy treatment:

- Group chambers
- Individual chambers
- Home chambers
I have not witnessed HBOT treatment in a group chamber, but have heard it is highly effective.
As for individual hyperbaric chambers (which are also referred to as “hard” chambers) I’ve seen two types. The first looks like the cockpit of a tiny airplane. In this type of chamber the patient sits up. The second type of individual chamber is a bed enclosed in a hard acrylic bubble, this type allows the patient to lie down.
In either unit, the chamber is locked and sealed and then the patient is put under pressure. When the desired pressure is reached, the patient typically puts on a plastic hood and breathes 100% oxygen for one hour. After the hour, the chamber is brought back to normo-baric pressure (it typically takes about a minute per square inch). A patient would need around 9 minutes to get to a PSI of 9. It would also take 9 minutes to come back to normo-baric pressure from a PSI of 9.
HBOT home chambers look like tents and are referred to as “soft” chambers. They do not allow the patient to dive to the same depths as medical chambers and are therefore not thought to be as effective. Home chambers (which provide mild-hyperbarics) are legal in the US, though not in Canada.
Length of Hyperbaric Oxygen Therapy Treatment
Typical HBOT treatment may consist of 40 one hour sessions 5-6 days per week. By doing the treatments consecutively it is thought that new capillaries are forced to grow (this process is called angiogenesis) in tissues that may be oxygen starved, or suffering from hypoxia. Treatment is prescribed by a doctor and is customized to the individual’s condition. Some patients will receive a prescription for 80 treatments at sessions greater than one hour, and pressures higher than 1.5 ATA.
Cellular Improvement Observed from Hyperbaric Oxygen Therapy
As previously mentioned, during HBOT the body’s natural healing processes are activated when oxygen is pushed beyond the red blood cells and into blood plasma. Although no experts, nor studies that I reviewed, make the claim that HBOT can revive dead tissues, studies do indicate that damaged tissues can be revived by HBOT treatment.
Here are some of the observable cellular benefits of HBOT:4
- Increased tissue oxidation –more oxygen to the tissues
- Improved mitochondrial redox –the powerhouse of the cell loses an electron, similar to anti-oxidation
- Preservation of mitochondrial integrity –the powerhouse of the cell retains structure, avoiding damage
- Hindering of mitochondrial apoptotic pathways –prevents the mitochondria from dying prematurely
- Anti-inflammatory effects –reduce and or prevent inflammation in the cells and body
- Epigenetic effects –targeting of oxygen and pressure sensitive genes improves mitochondrial function
Conditions Treated by Hyperbaric Oxygen Therapy
As mentioned, double blind studies have shown the effectiveness of HBOT in treating victims of stroke, burn, and delayed wound healing. Other studies show improvements in a wide variety of quality of life issues; here is a comprehensive list of the conditions that HBOT can improve according to the medical literature:
- Severe Burns
- Diabetic Wounds
- Near Drowning
- Decompression Sickness
- Carbon Monoxide Poisoning
- Severe Anemia7
Dr. Harch Leading Expert on Hyperbaric Oxygen Therapy
In 2010, Dr. Paul Harch wrote The Oxygen Revolution, the premier book on HBOT, a comprehensive and worthy read. Dr. Harch has published several studies on HBOT, and has a website with extensive medical information. According to Harch, “Hyperbaric oxygen therapy improves the quality of life of the patient in many areas when standard medicine is not working. Many conditions such as stroke, cerebral palsy, head injuries, and chronic fatigue have responded favorably to HBOT.”
Hyperbaric Oxygen Therapy and Military Veterans
A bill was introduced to congressional committee in January of 2015; if passed it would ensure access to HBOT at military medical facilities. There is significant anecdotal evidence that HBOT contributes to the healing of concussion and TBI.8, 9, 10
Hyperbaric Oxygen Therapy and Athletes
Olympic Swimmer Michael Phelps has used HBOT during his recovery, as has professional golfer Tiger Woods.11 In 2012, the Hall of Fame quarterback, Joe Namath, began HBOT. He had such great success, as documented in SPECT scans of his brain and cognitive testing, that he founded the Joe Namath Neurological Research Center in Jupiter Florida along with doctors Lee Fox and Barry Miskin, who plan to conduct a study testing the effects of HBOT on 100 people suffering from prolonged symptoms of brain injury.
Potential Side Effects of Hyperbaric Oxygen Therapy
Side effects of HBOT include potential build up of fluid in, and rupture of the middle ear, claustrophobia (individual chambers are tiny and locked), as well as myopia in certain rare cases; though doctors report that the retina returns to its normal shape and eyesight is restored within a few months of the conclusion of HBOT.12
History of Hyperbaric Oxygen Therapy
Apparently, the use of treatments akin to hyperbaric oxygen therapy date back a couple hundred years, with some anecdotes suggesting such treatments first began in the 17th century.
In the 1930’s the military developed and tested HBOT to treat deep sea divers with decompression sickness. Otherwise known as the “bends,” decompression sickness occurs when a scuba diver comes to the surface of a body of water too quickly, causing nitrogen to build up in the body, and dangerously so in the brain. The treatment for the bends is HBOT (increased pressure with 100% oxygen).
Animals and Hyperbaric Oxygen Therapy
As mentioned above, HBOT is an efficacious treatment for certain conditions suffered by humans; it is also a treatment used for animals. According to this paper from a veterinary journal:
Hyperbaric therapy utilizes several physiologic principles of how oxygen responds under pressure. The increase in concentration of oxygen in solution, based on its solubility under pressure, increases the diffusion gradient for its delivery deeper into tissues, which is the premise of HBOT. Ultimately the increases in dissolved oxygen generated by hyperbaric therapy have several physiologic effects that can alter tissue responses to disease and injury. As this technology becomes more available to clinical practice, HBOT should be considered as a therapeutic option [for animals].13
HBOT became a popular treatment for pets in the early 2000’s as an adjunct to traditional medical treatments. Before this a number of veterinarians had used hyperbaric therapy in small animal facilities. However, as HBOT gained popularity in the veterinary field, large animal hyperbaric chambers were developed and placed in many veterinary practices, rehabilitation facilities, and educational institutions in multiple countries. HBOT is now routinely used to treat swelling, trauma, non-healing wounds, and other ailments in animals including dogs, cats, ferrets, rabbits, and horses.14
Studies demonstrate that HBOT may assist in the healing of numerous conditions for which it is not currently approved by the FDA. Anecdotal evidence points to incredible results with HBOT for a variety of neurological conditions including autism, TBI, PTSD, and much more.
Whether or not you believe HBOT is an efficacious treatment or a scam, there is a lot to learn about it and the potential of this therapy is exciting for those of us with neurological issues that appear to be untreatable. What are your thoughts regarding HBOT? Leave a comment and let us know!
I fully understand MS being silent! I have had MS 36 1/2 years. For over 20 of those years people could not tell unless they were really looking that I had a MS.. The last few years have been rough on me because of all the chemicals that are sprayed in the fields. We eat organic and love your recipes!. I am now getting an electric wheelchair which should help my mobility. My left shoulder just doesn’t like to walk anymore with my Walker. Everyday is a new adjustment. I will be thinking of you and will pray for you.
Shirley, thanks for checking in! I really appreciate it. Yes, living in setting that gets more toxic every year is not easy for any of us. I am so sorry that we are dealing with this challenging disease process, but so heartened that we are on this healing path together :-)
I had to have this therapy about 8 yrs ago for a diabetic wound, it worked and I got well. Once I had a panic attack, but got right back in. I was told, at the time, it will make you look younger. I am so grateful it was available. Take care…
Hi Laura, thanks for your wonderful comment. I’m so glad we are on this healing path together :-)
What doesn’t your site cover? I was researching mild hyperbaric treatments and I was delighted when your site came up. I have osteomeylitis in my sacrum, hip and upper femur. Unfortunately, I was denied using the one at the hospital which should have been covered by insurance after my deductible portion. Instead, a friend and her brother have left theirs here with me for a month. I haven’t had to pay. I store lots of boxes. I am lucky to have the room! I do not know if a home mHBOT will work. I will see.
I have been enjoying trying more of your lovely recipes all the time. Just made the Goldfish with Asiago cheese , thyme and Korean red pepper flakes. Yum! Thanks for all the work on your site!
Sue, I’m so happy to meet you here! I’ve heard some good things about home HBOT. Please keep me posted :-)

Dr Harch has a free HBOT study in progress. He is looking for 8 more participants. Call to see if you fit criteria:
US Congress has funded and authorized a study on Hyperbaric Oxygen Therapy for Traumatic Brain Injury & Post Concussion Syndrome. The study is FREE to anyone who has had mild traumatic brain injury or post concussion syndrome in the last 10 years & fits criteria. Veterans with PTSD and headaches may also qualify because TBI-injured veterans are sometimes under-diagnosed as PTSD. Headaches can sometimes be a marker of TBI. Cara 504 427-5632 http://www.HBOTtbiStudy.org
if you do not fit criteria for this study, you can be treated as a private patient for another diagnosis. http://www.hbot.com
Hi Mrs. Harch! I’m so honored to see you here on my website! Thanks for leaving this comment :-)
Juliette Lucarini Harch says
Your website is lovely & informative. Thank you for heightening the awareness of the healing effects of HBOT. I hope you will join us at HBOT2017 11th International Symposium, in August, New Orleans. We will include info on HBOT for pets this year. Ahhhhh HBOT the cleanest medicine in the world for our bodies & it leaves no carbon footprint on our beautiful planet. Hope to meet you this summer.
Thanks Juliette! It’s so nice to see you here. I would love to speak at your event when my health has fully returned :-)
Jalu Sakti says
Wow, I never knew that hyperbaric oxygen therapy has been used since 2000, and that it can even treat ferrets! That truly is amazing. From what you said about the process, I can see how it would help swell injuries in these animals. I want to learn more about this therapy so that I can know exactly when would be the best times to have my dog use it.
Karen Genest says
Thank you for this article. Could you please reference that someone with an ASD should not use HBOT? Thanks in advance.
Hi Karen, I have not heard this, in fact, I know several doctors that recommend HBOT for austism. Thanks for sharing this differing information here.
I suffered a serious brain injury in1976 during a motorcycle accident with no helmet, at the age of 14. I landed in the grass and rolled many, many times. I started using a home hyperbaric chamber in May 2015, at the age of 53, and I am improving GREATLY. I can tell a difference each time that I use my chamber. I wait 2 hours after getting out of the chamber and start taking some powdered vit c in water, to stop the oxidative stress process.

India:I “We are passionate about the benefits of hyperbaric oxygen therapy can render to the world community at large”.
Hyperbaric oxygen therapy is a mainstream treatment and there is a growing need for this therapy in many areas.
Dissolving acceptable limits of oxygen is not alternative medicine, it is sound science and accepted as an adjunct treatment to many medical indications.
Hyperbaric Oxygen Therapy is a confused therapy among many medical, academic, and lay communities. The source of the confusion is a fundamental misunderstanding of the definition, principles, and mechanisms of action of hyperbaric oxygen therapy.
To be in a hyperbaric chamber is to be in the safest place in a hospital breathing high concentration of oxygen. A patient cannot suffer a stroke or heart attack while proper patient selection and safety guide lines are followed.
Over 2 million treatment sessions for neurological problems and other conditions have been carried out in the UK since 1982. These treatments have been carried out without a single serious accident.
It would be difficult to find a patient killed by Hyperbaric Oxygen Therapy in a year but of course there are plenty of deaths from lack of it.

I’ve had Fibromyalgia, Chronic Fatigue and Depression for over 15 years and live in Phoenix, Arizona. I was wondering if there was a proposed study coming here to Phoenix, to the West Coast or to the United States?
Since this treatment is not yet covered by insurance, the 40 treatments are too costly for the average person.
Thank you for leading this enormously valuable and tremendously needed study.
I know I would be able to work and have a productive and more fulfilling life without the fibro, et al.
Have a Blessed Day,

Lindsey Walls says
My brother-in-law tried to stomp out a pasture fire with his boots about a month ago. He is a diabetic and has neuropathy in his feet so he didn’t feel the fire burning his feet. He ended up with third degree burns on all of the toes on his right foot and three toes on his left, several of them burned to the bone. He was referred to a specialist who sent him to a burn center where he is receiving HBOT treatments every day, five days a week and will be taking these treatments for about two and a half months. The burn center is 85 miles from where my sister and her husband live and they make the commute every day. But with the skin graphs and the HOBOT treatments, it is amazing how much improvement we have seen in just four weeks. I really believe that were it not for these treatments he would have lost some toes, possibly all of them. In retrospect – with all of the travel and all of the medical expenses and the lost work on their ranch – my brother-in-law says now it would have been cheaper to just let the whole pasture burn. The one blessing, if any, is that with the neuropathy in his feet, he hasn’t experienced the pain associated with this degree of burns. So, I think there is great potential for HBOT treatments.

I had several different infections in a surgical wound that would not heal and had to be reopened and allowed to close naturally without suturing. I had Hbot treatment to heal the wound in 1993. I feel the treatment saved my life at the time. My internist was so committed to HBOT that he ultimately left his practice and does only hyperbaric treatment for a well known hospital in St.Louis Mo.
