The chamber
A pressure vessel — engineered to ASME standards — raises ambient pressure above 1.0 ATA, the same physics divers live by.
Pressure changes what oxygen can do. Scroll to dive into the science of hyperbaric oxygen therapy — from first principles to the frontier of enhanced medicine.
At sea level — 1.0 ATA — your red blood cells are already ~97% saturated. Hemoglobin is nearly full, and your plasma carries almost no oxygen at all. This is the ceiling of normal.
Inside a hyperbaric chamber, ambient pressure doubles while you breathe up to ~98% oxygen through a sealed mask. The rules of gas exchange begin to change.
Henry's law: gas dissolves into liquid in proportion to pressure. Under hyperbaric conditions, oxygen physically dissolves into blood plasma — reaching tissue that hemoglobin alone can't serve.
Hyperbaric oxygen therapy is one idea executed precisely: more oxygen, under more pressure, for a measured time.
A pressure vessel — engineered to ASME standards — raises ambient pressure above 1.0 ATA, the same physics divers live by.
A concentrator delivers up to ~98% O₂ through an inhale-activated mask, while exhaled CO₂ is vented outside the chamber.
Protocols typically run between 1.3 and 2.0 ATA. Pressure is the active ingredient — it's what moves oxygen into plasma.
85–110 minutes depending on the protocol, fully monitored, often in courses of 20–60 sessions.

The frontier of hyperbaric research isn't just delivering more oxygen — it's fluctuating it. Protocols that cycle oxygen up and down appear to signal the body's own regenerative machinery, the way altitude signals an athlete's blood — without the hypoxia.
"The fluctuations in oxygen delivery, rather than oxygen itself, trigger the regenerative cascade."

Randomized and controlled trials from the Sagol group have studied HBOT protocols in post-stroke and post-concussion cognition, reporting changes in brain metabolism and function.
A 2020 prospective trial reported telomere lengthening and reduced senescent-cell populations in older adults following a 60-session protocol — aging hallmarks, measured in blood.
Research in healthy adults and athletes has examined mitochondrial function, VO₂, and cognitive performance under repeated hyperbaric protocols.
We compile the peer-reviewed literature on hyperbaric oxygen — the established indications and the active research frontier — in readable form, with links to the primary sources. We report the research; we don't make medical claims.
Fourteen uses are cleared in the U.S. — including decompression sickness, carbon-monoxide poisoning, select non-healing wounds, and radiation tissue injury.
