Frequently Asked Questions about Hyperbaric Oxygen Treatment

What is Hyperbaric Oxygen (HBO2) treatment?

Initially used to treat underwater divers with the bends, HBO2 has been proven effective in treating many diseases. It does not replace other reliable treatments such as surgery and medication, but is generally prescribed in conjunction with other treatments.

Who can utilize Hyperbaric Oxygen (HBO2) treatments?

Accepted indications for hyperbaric oxygen therapy encompass a wide range of clinical conditions including: 

    • Air or Gas Embolism
    • Carbon Monoxide Poisoning
    • Crush Injury, Compartment Syndrome, and other Acute Traumatic Ischemias
    • Cyanide Poisoning
    • Decompression Sickness
    • Enhancement of Healing Selected Problem Wounds
    • Selected Refractory Anaerobic Infections
    • Exceptional Blood Loss Anemia
    • Gas Gangrene
    • Necrotizing Soft Tissue Infections
    • Osteomyelitis (Refractory)
    • Radiation Necrosis: Osteoradionecrosis and Soft Tissue Radiation Necrosis
    • Compromised Skin Grafts or Flaps
    • Thermal Burns
    • Diabetic Foot Wounds

How does it work?

Normally, the air we breathe is 21 percent oxygen. During HBO2, you will breathe pure oxygen (100 Percent) and the pressure surrounding your body will be slowly increased to two or three times normal. The increased oxygen you breathe will also increase the oxygen your blood carries to body tissues. This abundance of oxygen in your tissues enhances the repair of tissue damage.

Are there any side effects or after effects?

The most common effect is a "fullness" or popping sensation in your ears which lasts only briefly. As with most medical treatments, there may also be other effects. Such other effects are rare, and a staff member will discusses them with you in detail before treatment.

What are the treatments like?

HBO2 treatments include three phases: Compression, Prescribed time at pressure and Decompression. 
    • Compression: After the doors are closed, you can hear the compressing gas circulate. You can feel a "fullness" in your ears like flying or mountain driving. The attendant communicates with you and the speed of compression is adjusted to your comfort level. 
    • Treatment: Treatment begins when the pressure reaches the prescribed level. During the treatment you may rest, sleep, listen to music or watch television. 
    • Decompression: The attendant lets you know when the treatment is complete. The pressure is lowered slowly, again, at the rate comfortable to your ears.
