There are both acute and chronic
medical indications for HBOT. Currently the Undersea
and Hyperbaric Medical Society recognizes the following
as treatable medical conditions.
Hyperbaric Oxygen Therapy (HBOT)
- Osteoradionecrosis
- Soft-tissue radionecrosis
- Crush injury and compartment
syndromes
- Carbon monoxide poisoning
- Cyanide poisoning
- Decompression sickness
- Gas gangrene
- Poor wound healing - especially
chronic diabetic lower extremity ulcers
- Exceptional blood-loss anemia
- Chronic osteomyelitis
- Refractory actinomycosis
- Arterial gas embolism
- Acute peripheral ischemia
- Preservation of compromised
skin grafts and flaps
How does it work?
Hyperbaric oxygen is a mode of therapy in which
the patient breathes 100% oxygen at pressures greater
than normal atmospheric pressure while enclosed
in a clear, acrylic chamber. In contrast with attempts
to force oxygen into tissues by topical applications
at levels only slightly higher than atmospheric
pressure, HBOT involves the systemic delivery of
oxygen at levels 2-3 times greater than atmospheric
pressure. This treatment allows for increased levels
of oxygen to be delivered to tissues, which can
stimulate the growth of new capillaries and accelerate
the healing process. Hyperbaric medicine can also
inhibit the toxins of some bacteria, such as clostridium,
which causes gas gangrene. Increased oxygen at the
cellular level increases the white blood cell's
ability to have a lethal effect on both aerobic
and anaerobic organisms. It also enhances the cellular
uptake of some antibiotics. The greatest benefits
are achieved in tissues with compromised blood flow
and oxygen supply.
