hyperbaric oxygen therapy

hy·per·bar·ic ox·y·gen ther·a·py

treatment in which oxygen is provided in a sealed chamber at an ambient pressure greater than 1 atmosphere.
See also: hyperbaric oxygenation.

Farlex Partner Medical Dictionary © Farlex 2012

Administration of O2 in a chamber at > sea-level atmospheric pressure, which increases O2 dissolved in the blood from 1.5g/dL to 6.0 g/dL and O2 tension in tissues to nearly 400 mm Hg; this excess of O2 has various biochemical, cellular, physiologic benefits
Complications Barotrauma—air embolism, pneumothorax, tympanic membrane damage, O2 toxicity—CNS, pulmonary, reversible visual changes, fire or explosion and claustrophobia
Emergency medicine HOT is used for decompression sickness, gas embolism, extreme blood loss anemia, and as adjunctive therapy for clostridial myonecrosis and gangrene—associated with acute tissue hypoxia, crush injury, suturing of severed limbs. HOT is also used in smoke inhalation, cyanide intoxication, acute carbon monoxide poisoning, traumatic ischemia—as in compartment syndrome(s)—to enhance healing of recalcitrant or necrotic wounds, compromised skin grafts and flaps, chronic osteomyelitis, actinomycosis, and to prevent osteoradionecrosis
Fringe medicine HOT has been advocated by some alternative health care providers as an ‘oxidative’ therapy for ageing, grey hair, AIDS, alcohol and drug addiction, multiple sclerosis, stroke, vascular problems, and other conditions

Hyperbaric oxygen therapy (HBO)

A treatment in which the patient is placed in a chamber and breathes oxygen at higher-than-atmospheric pressure. This high-pressure oxygen stops bacteria from growing and, at high enough pressure, kills them.
