HBOT is a safe, natural healing process that infuses your body’s tissue with oxygen and naturally releases your body’s stem cells.  HBOT is FDA approved and has been used worldwide for more than 100 years to treat a wide range of conditions.

As we age, less oxygen is infused into our body’s tissue, causing muscles, brain, lungs, skin, heart, genitals, and other organs to atrophy. In addition, most diseases and injuries reduce oxygen delivery to the tissue.   HBOT releases your body’s stem cells, and it enables high concentrations of oxygen to reach deep into your body’s tissue.  This powerful combination of healing stem cells and energizing oxygen revitalizes, restores, and even regenerates aging or damaged tissue and organs throughout your body.

After 20-40 treatments, new blood vessels and new connective tissue develop. For up to 60 treatments, HBOT releases your body’s stem cells to wounded areas, which stimulates genes to repair hormones and regenerate tissue. After 25 – 35 treatments, the body’s tissues are permanently changed. After 40 treatments, cardiac capacity increases as new blood vessels form. The abundant oxygen kills harmful bacteria, viruses, pathogens, and microorganism diseases, which contributes to the healthiness of your cells and helps your body fight infection. 

Your body will naturally release stem cells by engaging the Hyperoxic – Hypoxic Paradox. Intermittently elevating oxygen intake at 1.4 ATA or higher for 20 minutes, and then removing the mask for 5 minutes tricks the body into experiencing hypoxia.

THE SCIENCE:  Elevated pressure decreases the size of the oxygen molecules (Boyle’s Law), and increases the volume of oxygen (Charles’ Law), enabling up to 1200% more oxygen to dissolve into your blood plasma (Henry’s Law).

HBOT helps many conditions that are caused or aggravated by reduced oxygen levels in the tissues.

During your HBOT sessions, you’ll relax for 60-90 minutes. You can wear regular clothing, use an electronic device to listen to music, read, watch a video, or take a nap. When you emerge from the chamber, you’re likely to feel relaxed and refreshed.

Yes. Nearly all top hospitals use HBOT.  It is approved by the FDA and in most other countries to treat many medical conditions because it works.  HBOT has been actively used and has been a researched body of medicine in the US and worldwide for nearly 100 years. 

Many Professional and Olympic athletes have used HBOT for decades* including Novak DjokovicRussell WilsonCristiano Ronaldo, LeBron JamesMichael PhelpsKirk CousinsJoe Namath, and many others.
HBOT’s benefits for athletic performance include:
– Decreased recovery from fatigue
– Decreased swelling and inflammation
– Decreased ligament and tissue healing time
– Decreased Achilles tendon injury healing time
– Improved alertness, reflexes, and memory

Yes. Israeli research finds HBOT reverses the aging process Published in Aging Nov. 2020: After 60 HBOT sessions over 3 months, 90 minute each with 5-minute oxygen breaks every 20 minutes, the test group showed a measurable reversal in two major processes associated with aging and its illnesses: telomeres on the chromosomes lengthened by 38%, and malfunctioning senescent cells reduced by 37%. Other factors such as diet, supplements, physical activity, stress management, and social support show positive health benefits, but little to no anti-aging benefits.

The brain is 2% of our body weight, but consumers 20% of our oxygen. HBOT increases oxygen and improves memory function. The Aging Brain can be reversed via HBOT, resulting in measurably improved memory.   HBOT also measurably improves erectile function.

Yes! The FDA has approved HBOT for at-home and clinical use. With a prescription from your doctor, you can purchase your own HBOT chamber.

Just as HBOT is FDA approved to heal serious wounds, concentrated oxygen increases blood circulation and oxygen delivery to skin cells, which also disables acne-triggering bacteria. Exfoliation, microdermabrasion, chemical peels, and moisturizers are also used in combination with HBOT for acne treatments.

The FDA’s Approved Indications for Use include:
1. Air or Gas Embolism
2. Carbon Monoxide Poisoning
a. Carbon Monoxide Poisoning Complicated by Cyanide Poisoning
3. Clostridial Myositis and Myonecrosis (Gas Gangrene)
4. Crush Injury, Compartment Syndrome and Other Acute Ischemias
5. Decompression Sickness
6. Arterial Insufficiencies
a. Central Retinal Artery Occlusion
b. Enhancement of Healing in Selected Problem Wounds
7. Severe Anemia
8. Intracranial Abscess
9. Necrotizing Soft Tissue Infections
10. Osteomyelitis (Refractory)
11. Delayed Radiation Injury (Soft Tissue and Bony Necrosis)
12. Compromised Grafts and Flaps
13. Acute Thermal Burn Injury

These indications are also approved for HBOT by the Undersea & Hyperbaric Medical Society’s (UHMS) Hyperbaric Oxygen Therapy Committee.


Mild HBOT (mHBOT) is FDA approved as an effective treatment, it’s low risk, and can safely be used in a home or nonmedical facility without medical supervision.

The FDA recognizes mHBOT for treating conditions such as altitude sickness and concussions. mHBOT has ≤95% O2 at 1.3 to 1.5 ATA.  At sea level (1 ATA), air contains 20.95% oxygen.

Concussions are treated at 1.3 – 1.5 ATA. Research studies show that stem cell release requires 1.4 ATA and above, and 1.4 ATA has been shown to improve autism symptoms in children. Sara’s Garden presents an inspiring collection of mHBOT success stories.

A growing body of evidence from research studies and clinical trials worldwide demonstrates the efficacy of mHBOT for improving a wide range of conditions including: concentration, alertness, memory, sleep, digestion, erectile disfunction, acne, altitude discomfort, muscle soreness before and after athletic exertion, hangovers, headaches, migraines, hearing loss, fibromyalgia, arthritis, Alzheimer’s disease, Lyme disease, neuropathy, restless leg syndrome, calming the nervous system, reducing the risk of heart attack, and more. 

In More Is Bettter:  The Recurrent Illusion of Higher Pressure HBOT In Chronic Brain Injury, Paul G. Harch, M.D, a leader in hyperbaric medicine, noted:    

  • “the aphorism that MORE IS BETTER” is just an illusion. Return to 1.5ATA/60 minutes and stay there.   Reserve 1.75ATA for treatment failures.”
  • “injured brain is exquisitely responsive to HBOT at pressures around 1.5 ATA. …  Multiple sclerosis is the best example.” 
  • “oxygen at pressure has a therapeutic window; too low a dose is ineffective and too high a dose is both ineffective and toxic.”
  • “the only well-tested dose of HBOT in cerebral palsy has been 1.5 ATA/60 minutes.”
  • Neubauer, the grandfather of HBOT in neurology in the United States…treated his first CP child in 1995 at 1.5 ATA and persisted with this pressure.

High Pressure HBOT (100% O2 at ≥2 ATA) is used by hospitals to treat serious and acute medical conditions – this requires certified medical staff due to safety risks and medical risks.  Costs are often in the range of $200 per hour. 

Many research studies demonstrate the effectiveness of mHBOT.  Here are a few: 

Angiogenesis: Hyperbaric oxygen induces a cytoprotective and angiogenic response in human microvascular endothelial cells

Arthritis1.25 ATA with 36% Oxygen reduced the reactive oxygen which are overproduced during arthritis

Autism: Improvement was shown in five domains with a significant level. Seventy-five percent of children shown improvement while 25% did not seem to respond to the treatment.

Autism: Children with autism who received hyperbaric treatment at 1.3 atm and 24% oxygen for 40 hourly sessions had significant improvements in overall functioning, receptive language, social interaction, eye contact, and sensory/cognitive awareness compared to children who received slightly pressurized room air.

Brain Injury Reversal:  A 2-year-old girl experienced cardiac arrest after cold water drowning. After HBOT, the patient had normal speech and cognition, assisted gait, residual fine motor and temperament deficits. MRI at 5 months after injury and 27 days after HBOT showed near-normalization of ventricles and reversal of atrophy. Subacute normobaric oxygen and HBOT were able to restore drowning-induced cortical gray matter and white matter loss, as documented by sequential MRI, and simultaneous neurological function, as documented by video and physical examinations.

Cerebral PalsyHow and why hyperbaric oxygen therapy can bring new hope for children suffering from cerebral palsy

Concussion: significant net improvements in PCS and PTSD symptoms with both doses of hyperbaric therapy.   

Gene expression: we identified changes in genes involved in adhesion molecule expression, angiogenesis and tissue remodeling, intracellular signaling, and cellular oxygen responses and redox signaling.

Fetal alcohol syndrome:  The patient’s subjective symptoms diminished 94%. Six months after these treatments, the patient’s verbal memory was maintained at 73%

Hyperglycemia: mild hyperbaric oxygen inhibits the decline in skeletal muscle oxidative capacity and prevents the hyperglycemia

Muscle Capacity:  Mild hyperbaric oxygen inhibited growth-related increase in blood glucose levels and decrease in muscle oxidative capacity of rats with metabolic syndrome because of improved oxidative metabolism.

Parkinson’s disease:  We conclude that exposure to mild hyperbaric oxygen is effective in preventing the progression of Parkinson’s disease.

Toxicity:  Improvement of attention span and reaction time with hyperbaric oxygen treatment in patients with toxic injury due to mold exposure

ATA stands for Atmospheres Absolute. Ground level is 1 ATA. 1.3 ATA is the pressure we feel at 10 feet underwater. 1.4 ATA feels like you’re 13.5 feet deep. 1.5 ATA feels like you’re 17 feet underwater.

Higher pressure increases the amount of oxygen in your blood, and is recommended for most users  1.3ATA is used by people whose ears are highly sensitive to pressure, and for other conditions such as concussion.   

No. Pressure is necessary for high volumes of Oxygen to be dissolved into the blood plasma and to penetrate your body’s tissue.

Yes. Just as doctors regularly prescribe medications for “off-label” conditions (i.e., not FDA approved), HBOT is routinely administered worldwide to treat over 150 off-label conditions. Although there is ample clinical evidence of success, most HBOT treatments have not been evaluated by the FDA’s extensive approval process.

Mild HBOT (mHBOT) significantly reduces the fire and medical risks of a high-pressure metal chamber filled with 100% pure oxygen, and does not cause the harmful side effects of many prescription drugs. However, because the FDA considers oxygen to be a medical gas, it classifies HBOT as a Class II medical device that requires a prescription.

Regarding safety and effectiveness, in 2013, the FDA issued a cautionary statement about HBOT for non-FDA-approved conditions.  The Alliance for Natural Health responded by detailing the safety and effectiveness of HBOT for many non-FDA-approved conditions. In 2021,  the ANH  explained the safety and effectiveness of HBOT for anti-aging, and that many conditions like this are not FDA approved because “it takes many years and millions and millions of dollars”. 

Mild HBOT is safe and comfortable for nearly all users, including the elderly and children. For some users, the elevated pressure, similar to taking off in an airplane, can cause discomfort of the ears and sinuses. Most people can equalize the pressure by yawning, swallowing, chewing, or pinching their nose and blowing gently, but if discomfort is severe or persistent, your doctor may recommend an alternative treatment.

HBOT is not recommended for pregnant women, or for people experiencing cold, flu, fever, sinus, nasal or chest congestion, or for those prone to claustrophobia.

Ask your doctor if any medications you’re taking could be affected by HBOT, such as: Bleomycin, Sulfamylon, Cisplatin, Disuriram (Antibuse®), Doxorubicin, medication patches, or ointments used for treating wounds. If you pursue a new medical treatment after beginning HBOT, consult your doctor about HBOT.

Before using HBOT, a medical check-up is advised, especially for individuals with health issues such as: Upper Respiratory Infection, Asthma, Collapsed Lung, Diabetes, Heart Condition, Pacemaker, COPD, Congenital Spherocytosisetc, Epidural Pain Pump, Eustachian Tube Dysfunction, or Seizure history.

Possible Side Effects of HBOT may include:
Barotrauma to the ear/sinuses (minimized with ear clearing techniques)
Fatigue (usually temporary)
Oxygen toxicity (rare, especially using lower pressures)
Certain drugs/substances may be metabolized differently, affecting dosing
Changes or worsening of cataracts (usually with higher pressures)
Increased nearsightedness (can be temporary; usually with higher pressures)
Herxing: Very ill patients may experience herxing after the first mHBOT treatment. They may briefly experience fever, chills and fatigue, which go away after a few treatments.

High pressure HBOT chambers that are used in medical facilities, with 100% pure O2 and 2.0 ATA pressure, can cause more serious health conditions including oxygen toxicity, paralysis, air embolism, and fire. Of course, keep any spark or fire away from the concentrated oxygen.

We accept Prescriptions/Referrals from Medical Physicians and Chiropractic Physicians in all 50 states, and from Licensed Naturopath (ND) in the following states: Arizona, Hawaii, Montana, New Hampshire, Oregon, Utah, Vermont, and Washington State. Ask your medical provider to specify, “Hyperbaric Chamber with Oxygen Concentrator”.

If you do not have convenient access to an authorized Physician, we can help you schedule a TeleMed visit.

Dr. Zayd Ratansi, ND reports that 5 sessions begins to provide an energizing boost and feeling of strength and well-being, as well as reducing inflammation throughout the body; 10 sessions begins to help with pain relief and repair of injuries; 20 sessions begins to mobilize stem cells that stimulate new collagen, new tissue, new blood flow and circulation; 40 sessions can help fight infections and combat aging and degenerative diseases. Ongoing sessions will continue to provide the benefits of oxygenating your body’s tissue. The benefits from the ‘HBOT reverses the aging process’ study were measured after 60 sessions, 90 minutes each, 5 days per week, for 3 months. 

To benefit from HBOT it’s important to commit to use it as directed, typically 5 or more days per week, 60 – 90 minutes per session. The number of sessions needed depends on the individual, the condition, and the pressure and concentration of oxygen in the chamber. 

It’s easy to use your O2Pod: 
1. Step inside the chamber
2. Turn on the machines and enter the chamber.
3. If it’s inflatable, zip the zippers closed.
4. Put on the mask or the oxygen headset and breathe
normally as you relax with a device, book, or take a nap.
5. After 60 – 90 minutes, to complete your session:
a. Open the Pressure Release control to depressurize the chamber to 0ATA.   
b. Unzip and exit the chamber.
c. Turn off the machines.

An air compressor is machine that pressurizes ambient air and maintains the air pressure inside the chamber. O2Pod features oil-free air compressors with robust filtration.

Ambient air contains 78.09% nitrogen and 20.95% oxygen. The O2Pod oxygen concentrator filters out the nitrogen, and delivers 93% – 95% purified oxygen into the mask.

No. Humans absorb oxygen through pulmonary system, not through the skin. According to Pascal’s law, pressure outside the body is also applied inside the body, so the inhaled oxygen is compressed by the pressure in the chamber. For example, when HBOT is used to treat decompression illness, pressure in the chamber compresses air bubbles inside the body.

Prices at clinics vary widely (e.g., $80 to $200+ per session), depending on services offered. Wellness protocols typically require 20 to 40 initial treatments, followed by ongoing maintenance. Clinics require scheduled sessions, travel, and sharing the HBOT chamber with other users, which is why many people prefer the price, convenience, time savings, and sanitation of an in-home HBOT chamber.  Of course, it’s important to consult your doctor and receive a Prescription for HBOT, and to treat any of the FDA approved medical conditions, we recommend HBOT at a medical facility. 

1662: British clergyman Henshaw used a pressurized chamber to treat a variety of conditions.
1878: French physiologist Paul Bert used HBOT to treat decompression sickness.
1928: Dr. Orville Cunningham’s “Steel Ball Hospital” reached 3 ATA
1940s: Military uses HBOT to treat deep-sea divers with decompression sickness.
1950s: Surgeons use HBOT during heart and lung surgery
1960s: Physicians use HBOT for carbon monoxide poisoning
NOW: FDA has approved HBOT for many Conditions and Use Cases

From the Greek, HYPER, meaning “above” or “beyond,” and BARYS, meaning “heavy.” In healthcare, hyperbaric therapy refers to treatment that applies elevated atmospheric pressure to a patient’s body, causing the blood plasma to absorb more oxygen. This helps to repair injuries and treat other adverse conditions.
