What is the difference between Hyperbaric Oxygen Therapy and Ozone Therapy?

Mechanism: Hyperbaric Oxygen Therapy — Henry's Law — increased O2 dissolved in plasma. Ozone Therapy — Oxidative stress → antioxidant upregulation. FDA status: Hyperbaric Oxygen Therapy — FDA-cleared for 14 conditions. Ozone Therapy — Not FDA-approved (used off-label). Delivery: Hyperbaric Oxygen Therapy — Breathing in pressurized chamber. Ozone Therapy — IV, rectal, topical, or autohemotherapy. Safety profile: Hyperbaric Oxygen Therapy — Well-established, rare adverse events. Ozone Therapy — Less studied, requires trained provider. Insurance: Hyperbaric Oxygen Therapy — Covered for approved indications. Ozone Therapy — Not covered.
