Hyperbaric medicine, also known as hyperbaric oxygen therapy(HBOT) is the medical use of oxygen at a level higher than atmospheric pressure. Several therapeutic principles are made us of in HBOT:
The increased overall pressure is of therapeutic value when HBOT is used in the treatment of decompression sickness and air embolism. For many other conditions, the therapeutic principle of HBOT lies in a drastically increased partial pressure of oxygen in the tissues of the body. The oxygen partial pressures achievable under HBOT are much higher than those under breathing pure oxygen at normobaric conditions (i.e. at normal atmospheric pressure).
A related effect is the increased oxygen transport capacity of the blood. Under atmospheric pressure, oxygen transport is limited by the oxygen binding capacity of hemoglobin in red blood cells and very little oxygen is transported by blood plasma. Because the hemoglobin f the red blood cells is almost saturated with oxygen under atmospheric pressure, this route of transport cannot be exploited any further. Oxygen transport by plasma, however is significantly increased under HBOT.

Patients inside the chamber will notice discomfort inside their ears as a pressure difference develops between their middle ear and the chamber atmosphere. This can be relieved by the Valsalva maneuver or by “jaw wiggling”. As the pressure increases further, mist may form in the air inside the chamber and the air may become warm. When the patient speaks, the pitch of the voice may increase to the level that they sound like cartoon characters. To reduce the pressure falls, the patient’s ears may “squeak” as the pressure inside the ear equalizes with the chamber. The temperature in the chamber will fall.
 

Initially, HBOT was developed as a treatment for diving disorders involving bubbles of gas in the tissues, such as decompression sickness and gas embolism. The chamber cures decompression sickness and gas embolism by increasing pressure, reducing the size of the gas bubbles and improving the transports of blood to downstream tissues. The high concentrations of oxygen in the tissues are beneficial in keeping oxygen-starved tissues alive and have the effect of removing the nitrogen from the bubblbe, making it smaller until it consists only of oxygen which is then re-absorbed into the body. After elimination of bubbles, the pressure is gradually reduced back to atmospheric level.

The United States, the Undersea and Hyperbaric Medical Society, known as UHMS, approved for reimbursement diagnoses for application of HBOT in hospitals. The following indications are approved uses of hyperbaric oxygen theraphy as defined by the UHMS Hyperbaric Oxygen

Therapy Committee.
  • Air or gas embolism
  • Carbon monoxide poisoning
  • Carbon Monoside Poisoning Compliccated by Cyanide Poisoning.
  • Clostridal Myositis and Myonecrosis. (Gas gangrene)
  • Decompression sickness.
  • Enhancement of healing in selected problem wounds.
  • Exceptional blood loss. (Anemia)
  • Intracranial Abscess.
  • Necrotizing soft tissue infections. (Necrotizing fasciitis)
  • Osteomyelitis. (Refractory)
  • Delayed radiation injury. (Soft tissue and bony necrosis)
  • Crush indury. Compartment syndrome and other acute traumatic ischemias.
  • Skin gafts & flaps. (Compromised)
  • Thermal burns.
In the United States, HBOT is recognized by Medicare as a reimbursable treatment for 14 UHMS “approved” conditions. An HBOT session costs anywhere from $100 to $200 in private clinics to over $1,000 in hospitals. U.S physicians may lawfully prescribing HBOT for “off-label” conditions such as Lyme Disease, stroke and migraines. Such patients are treated in outpatient clinics. In the United Kingdom most chambers are financed by the National Health Service, although some, such as those run by Multiple Sclerosis Therapy Centers, are non-profit.
