What is Hyperbaric Oxygen Therapy? (HBOT)

Hyperbaric Oxygen Therapy (HBOT) is a treatment that involves breathing 100% oxygen while in a High Pressure (Hyperbaric) chamber. This allows the body to transport higher levels of oxygen to deficient areas, accelerating your body’s natural ability to heal.

How it works

  • Hyperbaric Oxygen Therapy performed by placing the patient in a fully sealed hyperbaric chamber. The chamber is filled with 100% pure oxygen and is put under atmospheric pressure, allowing for more oxygen to be introduced in the same space.
  • The process of Hyperbaric Oxygen Therapy is very similar to deep sea diving or flying in an airplane. It is common for patients to experience a “popping” sensation in the ears during the pressurization/depressurization process.
