The Science
How Hyperbaric Oxygen Therapy Works
Hyperbaric oxygen therapy (HBOT) involves breathing concentrated oxygen inside a pressurized chamber. Based on Henry's Law of physics, increasing the atmospheric pressure around the body causes significantly more oxygen to dissolve directly into blood plasma, cerebrospinal fluid, and other body fluids. This dissolved oxygen can reach tissues and areas of the body that red blood cells may not easily access, particularly in regions with compromised blood flow.
Under normal conditions, oxygen is carried almost exclusively by hemoglobin in red blood cells. In a hyperbaric environment, the elevated pressure forces oxygen to dissolve into plasma at levels far beyond what is possible at sea level. This oxygen-rich plasma can penetrate damaged, swollen, or poorly vascularized tissues, delivering the oxygen needed to support cellular repair and metabolic processes.
OxyHealth chambers are available in both portable models for home use (operating at 1.3 ATA) and clinical models for medical facilities (capable of higher pressures). All OxyHealth chambers are FDA-cleared and manufactured under strict quality controls to ensure safety and effectiveness.
Evidence-Based
Research-Backed Benefits
Enhanced Wound Healing
The FDA has recognized HBOT for 14 medical conditions, many related to wound healing. HBOT supports the formation of new blood vessels (angiogenesis) and enhances oxygen delivery to wound sites, which may accelerate the repair of diabetic ulcers, surgical wounds, and radiation-damaged tissue.
Reduced Inflammation
Research suggests that HBOT may help modulate the inflammatory response by reducing levels of pro-inflammatory cytokines, including TNF-alpha, IL-1, and IL-6. Studies have shown that pressurized oxygen can help downregulate inflammatory pathways, potentially supporting recovery from both acute and chronic inflammatory conditions.
Improved Athletic Recovery
A study published in the British Journal of Sports Medicine (Staples et al., 1999) found that athletes using HBOT experienced faster recovery from ankle sprains compared to a control group. Many professional athletes use HBOT to support recovery from training and competition.
Anti-Aging and Longevity
A landmark study from Tel Aviv University (Hachmo et al., 2020, published in the journal Aging) found that HBOT increased telomere length by over 20% and reduced senescent cell populations by up to 37% in aging adults. These biological markers are closely associated with cellular aging.
Enhanced Cognitive Function
Research suggests that HBOT may improve cerebral blood flow and support neuroplasticity. Studies published in journals such as Frontiers in Human Neuroscience have explored how increased oxygen delivery to the brain may support cognitive performance, memory, and recovery from neurological conditions.
Increased Stem Cell Mobilization
Research has shown that HBOT may stimulate the release of stem cells from bone marrow into the bloodstream, with studies reporting up to an 800% increase in circulating stem cells after a series of treatments. These stem cells play a key role in tissue repair and regeneration throughout the body.

Frequently Asked Questions
Hyperbaric Chamber Benefits FAQ
Hyperbaric oxygen therapy (HBOT) works by increasing oxygen delivery throughout the body under elevated pressure. Research has explored its role in wound healing, inflammation reduction, athletic recovery, cognitive support, and cellular regeneration. The FDA has cleared HBOT for 14 specific medical conditions, including diabetic foot ulcers, decompression sickness, and carbon monoxide poisoning. Additional research continues to investigate benefits across other areas of health and wellness.
Yes, hyperbaric oxygen therapy is considered very safe when administered in FDA-cleared chambers following proper protocols. OxyHealth chambers are manufactured under ISO 13485 quality management standards and are built to ASME PVHO-1 pressure vessel safety standards. The most common side effect is mild ear pressure during pressurization, similar to what you might experience during air travel. OxyHealth has delivered over 19,000 chambers worldwide with an exceptional safety record. Always consult a healthcare provider before starting HBOT.
A typical HBOT session lasts between 60 and 90 minutes, depending on the protocol recommended by a healthcare provider. During the session, you relax inside the chamber while breathing concentrated oxygen at elevated pressure. Most people read, watch videos, or rest during their session. The number and frequency of sessions varies based on the condition being addressed. Some wellness protocols involve 20 to 40 sessions, while acute conditions may require different schedules as determined by a physician.
Yes, OxyHealth manufactures portable hyperbaric chambers specifically designed for safe home use. Models like the Vitaeris 320 and Respiro 270 are FDA-cleared, easy to set up, and designed for daily use in a residential setting. Home chambers typically operate at 1.3 ATA, which is considered mild hyperbaric therapy. Many users find that having a chamber at home allows them to maintain consistent treatment schedules without the inconvenience of traveling to a clinic for each session.
Insurance coverage for HBOT varies depending on the condition being treated and the insurance provider. Medicare and many private insurers cover HBOT for FDA-cleared indications such as diabetic foot ulcers, radiation injury, and certain non-healing wounds. Coverage for off-label or wellness uses of HBOT is generally not covered by insurance. OxyHealth offers flexible financing options to make chamber ownership accessible. Contact OxyHealth for more information about financing and payment plans.
Mild hyperbaric therapy, sometimes called mHBOT, typically operates at pressures of 1.3 ATA and is available in portable chambers suitable for home use. Clinical or hospital-grade hyperbaric therapy can reach pressures up to 3.0 ATA and is administered in rigid monoplace or multiplace chambers in medical facilities. Both approaches increase oxygen delivery beyond normal levels, but higher pressures dissolve proportionally more oxygen into blood plasma. The appropriate pressure level depends on the condition being addressed and should be determined by a healthcare provider.
The number of sessions needed varies widely depending on the individual and the reason for treatment. Some people report noticing changes after just a few sessions, while conditions such as chronic wounds or radiation injury may require 30 to 40 sessions for optimal outcomes. Wellness and recovery protocols commonly involve 20 to 40 sessions. Consistency is key, as the benefits of HBOT appear to build with regular, repeated treatments. A healthcare provider can help determine the right protocol for your specific needs.
While HBOT is safe for most people, there are some contraindications. Individuals with untreated pneumothorax (collapsed lung) should not use hyperbaric therapy. People with certain types of ear infections, severe claustrophobia, or specific lung conditions should consult their physician before starting HBOT. Some medications may also interact with increased oxygen levels. It is important to provide your healthcare provider with a complete medical history before beginning any hyperbaric oxygen therapy protocol.
