Summary
Dr. David Jockers interviews Dr. Amir Hadanny, a neurosurgeon and chief medical research officer at Aviv Clinics, about the science and clinical applications of hyperbaric oxygen therapy. Dr. Hadanny explains Henry's law and how breathing 100% oxygen under pressure dissolves significantly more oxygen into blood plasma, enabling healing of tissues that lack adequate blood flow and oxygenation. The conversation covers HBOT's established uses for diving accidents, non-healing wounds, and radiation injury, as well as emerging neurological applications including traumatic brain injury, post-concussion syndrome, stroke recovery, fibromyalgia, and PTSD. Dr. Hadanny describes his team's randomized controlled trials showing cognitive and neurological improvements in TBI and stroke patients, with results translating to meaningful quality-of-life gains. A key focus is HBOT's potential for healthy aging. Research on adults over 64 demonstrated improvements in cognitive function, physical performance, and aging biomarkers. Dr. Hadanny also draws a clear distinction between medical-grade hard chambers at 1.5-2 atmospheres with 100% oxygen and unregulated soft shell chambers, cautioning against home use of soft chambers due to safety concerns and lack of clinical evidence for their efficacy.
Key Points
- Henry's law explains HBOT: pressure dissolves more oxygen into blood plasma, similar to carbonation in a sealed can
- Medical-grade HBOT uses 1.5-2 atmospheres with 100% oxygen, while soft shell chambers at 1.2-1.3 atmospheres have no proven clinical efficacy
- Randomized controlled trials show significant cognitive and neurological improvement in traumatic brain injury patients
- Over 50% of stroke survivors suffer cognitive issues that HBOT can meaningfully improve
- HBOT research on healthy adults over 64 showed improved cognitive function, physical performance, and aging biomarkers
- Fibromyalgia and PTSD, both brain-based conditions, respond well to HBOT protocols
- Typical neurological protocol involves 60 sessions over 12 weeks, five days per week, two hours per session
- Aviv Clinics combines HBOT with personalized cognitive training inside the chamber for synergistic benefits
Key Moments
The Coca-Cola analogy for how pressure dissolves oxygen into blood
Dr. Amir Hadanny uses the Coca-Cola can analogy to explain Henry's Law and why pressure is essential for HBOT. Just as CO2 dissolves in a sealed can under pressure and escapes when opened, oxygen dissolves into blood plasma under hyperbaric conditions in ways that breathing oxygen alone cannot achieve.
"So there is a physical law called Henry's law that says that you are able to dissolve more gas molecules in a liquid under pressure. And the best way to understand this law is a Coca-Cola can. Again, I'm not a Coca-Cola advocate here, but think about that. So you have a lot of CO2 gas dissolved in the can."
Randomized controlled trial results astonished skeptical researchers
Dr. Hadanny describes how he and his mentor designed a randomized controlled trial on TBI patients expecting to prove HBOT was just placebo, but were astounded by the results showing significant neurological and cognitive improvements that translated to better daily life functioning.
"And we were astounded. We were really, really astounded. You know, comparing the treated group to the control group, we saw amazing both neurological effect as well as significant cognitive effects, really translating to improving day-to-day life or what we call ADL activity of daily life, improving the quality of life of these patients, being able, going back to work."
HBOT can reverse the aging process by improving cognitive and physical function
Dr. Hadanny describes a landmark study on healthy adults over 64 showing that a specific hyperbaric protocol improved cognitive function, physical function, and actual aging biomarkers, demonstrating the ability to change how we age.
"And we found we are able to improve the aging process. We are able to improve cognitive function as well as physical function along with actual aging biomarkers."
Typical HBOT protocol is 60 sessions over 12 weeks with cognitive training
Dr. Hadanny outlines the Aviv Clinics protocol for neurological conditions: 60 sessions over 12 weeks, five days per week, two hours per session in a multiplace chamber seating up to 14 people, combined with personalized cognitive training exercises.
"So five sessions a week."
