HBOT / Oxygen Chamber
Breathing 100% pure oxygen at pressures 1.5–3x higher than normal atmospheric pressure inside a pressurized chamber, dramatically increasing oxygen delivery to tissues throughout the body.
How it works
Increased ambient pressure forces dissolved oxygen directly into plasma (bypassing hemoglobin saturation limits), achieving tissue O2 levels up to 10–15x normal. This hyperoxygenation activates HIF-1α pathways, promotes angiogenesis, reduces oxidative inflammation, enhances leukocyte bactericidal activity, and stimulates stem cell mobilization from bone marrow.
Reported benefits
- Wound healing acceleration (diabetic ulcers, radiation injuries)
- Traumatic brain injury and concussion recovery
- Anti-aging and longevity support
- Neurological condition support (post-stroke)
- Long COVID symptom management
- Athletic performance and recovery
- Carbon monoxide poisoning treatment
Regulatory status
Approved for: Decompression sickness, CO poisoning, Non-healing wounds, Radiation injuries, Multiple approved medical indications
HBOT is an established medical treatment in the EU for multiple indications. Hyperbaric chambers are Class IIb/III medical devices requiring CE marking. European Committee for Hyperbaric Medicine (ECHM) publishes evidence-based guidelines.
Approved for: CO poisoning, Decompression sickness, Non-healing wounds, Radiation tissue damage
HBOT available on NHS for approved indications. Hyperbaric chambers registered as medical devices. Private wellness HBOT widely available. British Hyperbaric Association oversees standards.
Approved for: Decompression sickness, CO poisoning, Diabetic foot ulcers, Radiation tissue damage, Non-healing wounds, Necrotizing infections, Osteomyelitis, Air/gas embolism
FDA has approved HBOT for 13 specific medical conditions. Anti-aging, brain optimization, and athletic recovery are off-label uses. Mild HBOT (1.3–1.5 ATA, soft chambers) sold as wellness products; medical HBOT (2.0–3.0 ATA) requires physician prescription.
