Hyperbaric Oxygen Therapy



Hyperbaric Oxygen Therapy is a medical treatment which enhances the body's natural healing processes by inhalation of 100% oxygen in a total body chamber, where atmospheric pressure is increased and controlled. 


Simply Oxygen

Under normal circumstances, oxygen is transported throughout the body only by red blood cells. With HBOT, oxygen is dissolved into all of the body's fluids, the plasma, the central nervous system fluids, the lymph, and the bone.


Faster Healing

This way, extra oxygen can permeate all damaged tissues and the body can support its own natural healing process. The increased oxygen greatly enhances the ability of white blood cells to kill bacteria, reduces swelling and allows new blood vessels to grow rapidly.

"A simple, non-invasive treatment"

Ontario HBOT





Greatly enhances the ability of white blood cells to kill bacteria


Reduces swelling and inflammation throughout the entire body

Enhances the bodies natural healing processes

Dissolves into all of the body's fluids, plasma, central nervous system, lympth, and bone 


Oxygen is carried to areas where circulation is blocked or diminished


Increases the growth rate of new blood vessels and nerve endings


Middle ear injuries, including leaking fluid and eardrum rupture, due to increased air pressure.


Lung collapse caused by air pressure changes (barotrauma)


Seizures as a result of too much oxygen (oxygen toxicity) in your central nervous system

We are Proud...

that after 12 years operating performing over 60,000 hyperbaric treatments, none of our patients have ever experienced any of the described risks.

Knowledge, experience, and dedicated staff is the perfect recipe for a safe environment at Ontario HBOT.
Red Umbrella - Safety and Risks




Hyperbaric Oxygen Therapy is a very safe procedure. Complications are rare, however there are potential risks.

The air you are breathing right now is 21% oxygen, 78% nitrogen, and other mixed gases. During HBOT, you are breathing 99.993% pure medical grade oxygen. 

Over time, highly oxygenated blood vessels start going through a process called angiogenesis, where new blood vessels begin forming from pre-existing vessels formed in the earlier stage of vasculogenesis.

In addition, HBOT increases the amount of oxygen your blood can carry. This increase temporarily restores normal levels of blood gases and tissue function to promote healing and fight infection.

Healing Accelerated

Expedited Recovery

Hyperbaric oxygen has several specific biological actions which can enhance healing processes. These include: 

  • Hyper-oxygenation of tissue

  • Vasoconstriction

  • Down regulation of inflammatory cytokines

  • Up-regulation of growth factors

  • Antibacterial effects

  • Leukocyte effects

HBOT is an excellent adjunct therapy, as part of an overall treatment plan.

We've compiled a list of frequently asked questions garnered by our walk-in, phone, and online inquiries. Of course, any further questions may be answered by a member of our care team.
  • Why do you go under pressure in the hyperbaric chamber?
    Under pressure, oxygen is forced into blood plasma. At 3 ATA of pressure, plasma carries more dissolved oxygen than hemoglobin does. The dissolved oxygen in plasma at this pressure is capable of sustaining life without negative results even in the absence of hemoglobin. Oxygen is a powerful vasoconstrictor. Breathing oxygen at normal pressure reduces inflow to the capillaries by about 20%, resulting in compromised tissue becoming hypoxic. But in the hyperbaric environment, high plasma oxygen levels can maintain tissue oxygen levels and capillary outflow even with vasoconstriction.
  • Can anyone go into the Hyperbaric Chamber?
    At Ontario HBOT, we have treated individuals as young as 6 months and as old as 99. All prospective patients go through a qualification process before their first treatment. The main reasons individuals DO NOT qualify to go into the hyperbaric chamber are considerable heart issues and/or significant lung issues.
  • Do I need a referral from a doctor?
    No, you do not need a referral from a doctor. Health records may be required if you have various medical issues that need clarifying during the qualification process. If you are looking to qualify for HBOT covered under OHIP for one of the 14 qualifying conditions, a referral from a referring physician is preferred and dramatically speeds up the qualification process; however one is not necessary.
  • What is allowed in the Hyperbaric Chamber?
    The following items are allowed in the hyperbaric chanber: Water bottle (brand new, given prior to first treatment) Post-sugical apparatus provided by referring physician Face cloth (100% cotton, provided by hyperbaric staff) Other items approved by the hyperbaric staff The hyperbaric technician will approve or deny any items going into the hyperbaric chamber regardless of any third-party approval if they deem the item unsafe in their professional opinion.
  • How does someone with claustrophobia handle the hyperbaric chamber?
    Our hyperbaric chambers are the second-largest monoplace chambers on the market. They also feature the highest quality acrylic cylinders, which result in a very open feeling. In addition, the technician can start your movie before going into the chamber to distract from the feeling of confinement. Note: If for any reason you are not able to get over your claustrophobia while onboarding into the chamber, you will NOT be charged for your treatment* *Only applicable for private pay patients
  • How much time should I allow for Hyperbaric Oxygen Therapy (HBOT)?
    Private hyperbaric sessions run 75 minutes in length. At Ontario HBOT, all of our chambers run ON TIME. This means that your scheduled time is when are you going into the chamber. New patients are advised to come early in order to change into the cotton scrubs provided, go to the washroom etc. In addition, there is no formal reception area requiring you to check-in before every treament. This allows for a very efficient "in-and-out" experiece, especially for those doing a multiple treatment protocol.
  • How does scheduling work at Ontario HBOT?
    The first treatment commences at 8:00AM, with the last treatment going in around 3:00/3:30PM. All treatments are booked on the hour or half hour. If you are booked at 8:00AM, doors are open at 7:45AM to allow time to change and use the restroom. Note: All chambers run ON TIME. Your scheduled time is when you are going into the hyperbaric chamber, not when you are pulling into the parking lot. If you are late for your treatment we will do our utmost to accomodate however we cannot guarantee your full treatment time.
  • What pressure do you use during hyperbaric oxygen therapy?
    The pressure in the hyperbaric chamber, measured in atmospheres absolute (ATA) in this case, is determined based on your specific condition. At Ontario HBOT, your treatment is tailored for your individual needs by our highly trained, experienced staff. We take into account research and studies performed by leading hyperbaric experts worldwide, in order for your protocol for achieve maximum effectiveness. It is important to note that patients at Ontario HBOT are always in constant contact with all members of the care team, and are encouraged to provide daily feedback on their symptom improvement and any other questions or concerns they may have. As symptoms improve and eventually begin to "plateau," the ATA may be increased at the care team's discretion.
  • How long does it take to pressurize and depressurize the hyperbaric chamber?
    On average, it takes approx. 6 - 7 minutes to pressurize, as well as depressurize the hyperbaric chamber. However, if a patient is having problems with their ears, the hyperbaric technician may employ any number of techniques to eliminate any discomfort they may be having. As a result, the time to pressurize would increase. In regards to depressurizing, the ears pop on their own and return to their normal state. In the case of an emergency, the technician has the ability to depressurize the hyperbaric chamber in as little as 90 seconds. Please note: all information is specific to the Perry Sigma 36 Hyperbaric Chamber used at Ontario HBOT unless stated otherwise.
