Hyperbaric Oxygen Therapy (HBOT) and Ozone Therapy both use oxygen-based approaches to support healing, but they work through fundamentally different mechanisms. Understanding these differences matters because the therapies are not interchangeable, and the evidence base behind them differs substantially.
How HBOT Works
HBOT delivers concentrated oxygen at elevated atmospheric pressure, typically 1.5 to 2.0 ATA in clinical settings. Under pressure, oxygen dissolves directly into blood plasma, bypassing the normal hemoglobin-dependent delivery system. This allows oxygen to reach tissues with compromised circulation, including wounds, inflamed areas, and regions affected by radiation damage.
The proposed mechanisms include angiogenesis (new blood vessel formation), changes in white blood cell function, and reduced edema through vasoconstriction. These mechanisms have been studied in clinical settings for decades.
How Ozone Therapy Works
Ozone Therapy introduces ozone gas (O₃) into the body through various methods: injection, insufflation, or mixing with blood that is then reinfused. The proposed mechanism involves triggering oxidative stress in a controlled way to stimulate antioxidant defenses and immune modulation. Ozone also has antimicrobial properties, which proponents cite for treating infections.
The regulatory status of ozone therapy is different from HBOT. The FDA has not approved ozone as a medical treatment in the United States, citing insufficient evidence for safety and efficacy. Some practitioners offer it as a complementary therapy, but the clinical research is less extensive than that supporting HBOT, and methodological quality varies.
Key Differences
HBOT increases the amount of oxygen dissolved in your blood. Ozone therapy introduces a reactive molecule intended to trigger biological responses. The most common side effect of HBOT is ear pressure during compression; other risks are screened for before your first session. Ozone requires careful dosing because excessive exposure causes oxidative damage.
HBOT has the larger research base of the two, and post-surgical recovery is one of the areas studied. Its proposed mechanisms have been studied at the cellular level, and clinical protocols are standardized. Ozone therapy may have applications, but patients should be aware that the regulatory landscape and research base differ significantly.
HBOT at OxyRenew
At OxyRenew in West Hollywood, we offer Hyperbaric Oxygen Therapy in a hard-shell chamber operating at 2.0 ATA. Sessions are for wellness and recovery; clients come for many reasons. Each session is private and supervised by a Certified Hyperbaric Technician who can answer questions about how sessions run.
