Dissolved oxygen
Under increased atmospheric pressure, breathing high-concentration oxygen increases the amount of oxygen dissolved in plasma.
Learning / Foundations
How HBOT works.
Start with the exposure itself, then compare protocols, research questions, and session safety.
How it works
More oxygen can dissolve in the blood under pressure.
Hyperbaric oxygen therapy (HBOT) involves breathing oxygen in a pressurised environment.
Under increased atmospheric pressure, more oxygen can dissolve into the blood plasma compared with breathing oxygen at normal atmospheric pressure. For clinical purposes, the Undersea & Hyperbaric Medical Society (UHMS) defined pressure as at least 1.4 ATA while breathing near-100% oxygen.
Oxygen delivered through the system's specified breathing setup is what a person actually receives. The gas inside the HBOT cocoon® and the oxygen a person breathes are not always identical.
Angiogenic signalling
Research has reported changes in signalling pathways associated with angiogenesis, including VEGF-related pathways, after repeated HBOT exposures.
Cellular signalling
HBOT has been reported to influence oxygen- and redox-sensitive cellular signalling pathways.
Stem and progenitor cells
In a human study using one specific protocol, 2.0 ATA oxygen for 2 hours, circulating CD34+ stem and progenitor cells increased.
Common research questions
Four areas readers commonly ask about.
01
Sleep and rest — tracked through subjective questionnaires, daytime sleepiness and wearable trends.
02
Recovery and performance — studied across specific injury, fatigue and rehabilitation contexts.
03
Healthy-ageing markers — emerging work includes vascular, inflammatory and cellular biomarkers.
04
Cognitive research — studied in defined populations with specific protocols and outcome measures.
The meaning of each result depends on the population, protocol, comparison group, and outcome measured.
Follow the path from mechanism to a useful outcome.
A mechanism explains what may change biologically. To understand whether that change is useful, continue through the measured marker, clinical outcome, and individual decision.
Mechanism
Pressure can increase dissolved oxygen. This is the biological starting point.
Measured marker
A study may observe a change in a questionnaire, wearable metric or biomarker.
Clinical outcome
A meaningful health outcome needs an appropriate population, comparison, and study design.
Individual decision
Suitability still depends on personal risks, goals, product instructions and qualified advice.
Safety is part of the product
Five checks before a session.
- 01
Follow the exact manufacturer instructions for the specific device and configuration.
- 02
Make sure a trained operator provides the supervision or monitoring required for that setting.
- 03
Follow the fire-prevention rules, approved clothing requirements, prohibited-item list, and grounding instructions for that chamber.
- 04
Complete cleaning, maintenance, and safety checks on the schedule specified for the chamber.
- 05
Ask a qualified healthcare professional to assess medical suitability, contraindications, and persistent symptoms.
Continue with the question that matters to you.
Continue into sleep, longevity, condition evidence, or a direct system comparison.
Sleep and rest
Sleep stages, rest habits, and when to seek care for persistent symptoms.
Longevity
The Hachmo et al. 2020 study, read as a blood-cell result rather than extra years.
Condition questions
Stroke, TBI, dementia, autism/ADHD, cancer care, reproductive health, wounds, and Long COVID.
Systems and products
Model pressure and oxygen setup live on the comparison guide.
