Hyperbaric Oxygen Therapy (HBOT)

Oxy Health Chamber

Hyperbaric oxygen therapy (HBOT) is the application of higher atmospheric pressure and additional oxygen to your body in an enclosed chamber.

Hyperbaric treatments have the potential to improve energy levels, regenerate tissue by mobilizing stem cells, create new blood vessels (angiogenesis and vasculogenesis), decrease inflammation, relieve pain, and improve the immune system. 


Proper application of HBOT has been shown to:

Dramatically change gene expression, especially genes associated with inflammation and healing. It appears that up to 8101 genes are either expressed or suppressed with HBOT making it one of the oldest, most enduring and most effective gene therapy.

Improved healing and reduced inflammation. One of the ways this occurs is through changes in reactive oxygen (ROS) and nitric oxide (NOS) pathways. These pathways are triggered and create a four-hour window of time in which cellular debris is removed and there is generalized healing.

Better neurologic and cognitive function, reduction in fatigue and improved performance. HBOT can be highly dose-dependent so it is important to adjust appropriately Most of the historical science behind hyperbarics was done in dive medicine for scuba injuries which required higher pressures (2 to 3 atmospheres) and higher amounts of oxygen (up to 100%). Over the last 10 years, there has been significant realization that both the dose and the pressure of oxygen are important variables that need to be individually optimized for each individual patient depending on their situation.

Higher is not always better: Lower pressure hyperbarics in many situations are better if not comparable to higher pressure hyperbarics, especially in situations that require a longer period of time to recover such as neurologic conditions. Hyperbaric is like most other drugs – the right dose matters.

Synergies: If there are other therapies that are being used for a condition (e.g., intravenous medication, supplements, pharmaceuticals), less total dose of hyperbaric therapy is needed. There can be synergies between hyperbaric therapy and the other regimens.

Brain resilience. Studies with patients with traumatic brain injury have shown that there can be a significant amount of the brain that is wounded that can recover with HBOT. It appears that cells may be “stunned” for years but can recover with the right dosage of HBOT.

Dose response and duration. Given that hyperbarics may stimulate neuroplasticity, it is critical to get the right dose-response for treatment. We should be able to see an initial response within the first 40 sessions of treatment and there may be further benefits with additional treatment.


HBOT is a method of delivering extra oxygen into the body, mainly through the process of increasing the pressure that the body is normally under. In terms of HBOT, pressure is normally quantified in ATA and currently, we are all standardized to be less than 1.0 ATA of atmospheric pressure.

When someone undergoes hyperbaric therapy, the pressure becomes greater than 1.0 ATA and in hospitals and wound care centers can typically reach 2.0 or even 3.0 ATA. Each atmospheric pressure represents 33 feet of seawater, so at 2.0 ATA, it would be equivalent for you to be at a depth of 33 feet below sea level.

Once at this depth, 100% oxygen through a non-rebreather mask will be administered for the full duration of the treatment, which normally lasts for 60 to 90 minutes per session, and this procedure can be repeated twice per day with a 4-hour break in between.

Many doctors and clinical researchers in the field of hyperbaric medicine believe that HBOT may help many more conditions and improve quality of life. Please be aware that if you are using this to treat a medical condition other than the 13 conditions listed below, then the FDA considers this an ‘off-label’ treatment and wishes you to make sure that you have sought out all FDA-approved treatments first and fully understand the benefit to risk ratio before making your decision.


FDA approved indications:

  • Decompression Sickness
  • Gas embolism
  • CO and Cyanide poisoning
  • Selected aerobic and anaerobic soft tissue infections
  • Osteomyelitis
  • Intracranial abscess
  • Management of Fungal disease
  • Radiation injury to tissue
  • Exceptional blood loss/anemia
  • Crush injury/compartment syndrome
  • Ischemia reperfusion injuries
  • Skin grafts and flaps
  • Healing in selected problem wounds
  • Treatment of thermal burns

Hyperbaric Treatment at Rezilir Health 

We currently offer hyperbaric oxygen therapy treatments in two high-pressure Fortius 420 chambers that are capable of being pressurized from 1.3 ATA to 2.0 ATA.  Your session in the chamber will run anywhere from 30 to 90-minutes, depending on the treatment plan created specifically for you. Pressurization up to the appropriate atmospheric pressure will take 15-20 minutes, or possibly longer (depending on your ability to adjust for the increased pressure). Depressurization will be about the same depending on your ability to adapt. The temperature in the chamber may rise by 10 degrees so you may feel warm, but in contrast, you may also feel cold, especially during depressurization. Please dress appropriately. You will not need to change into special static free clothing for this treatment as we do not pressurize the chamber with 100% oxygen. 

You will be assessed by the nurse practitioner or another clinician to make sure it is safe for you to enter the chamber.  If you have had a recent upper respiratory or ear infection, you may find it uncomfortable to reach the appropriate pressure, which could prevent you from completing treatment. If you have had recent surgery to your ear drum, trauma to your chest (such as a car accident or surgery), collapsed lung, a clot to your lung or anywhere else in your body, you will not be allowed into the chamber. If you are actively being treated for cancer, have clips in your brain, brain tumor or any brain abnormality, you will be required to have a letter of approval and an order for treatment from your Oncologist or Neurologist. During your assessment, it will be determined whether you will be allowed in the chamber.  

Rezilir’s chambers are solid metal, not clear, which may bother some people. If you have severe claustrophobia, you can visit the office and see how large the chamber is and possibly even getting in to see how comfortable it is on the inside, without pressure. Each chamber has 5 windows which allows for plenty of light to shine inside. You will be allowed to bring inside with you a computer, tablet, or smartphone to help pass the time. Brain games are also a great way to spend your time inside the chamber and help to increase neurogenesis or the growth of the brain.   

Our chambers are thoroughly cleaned and disinfected with hydrogen peroxide after each use. Your safety and health are considered a priority here at Rezilir Health.
