Referring to a treatment in which someone is given oxygen at high pressure, used to treat carbon monoxide poisoning.
A pressure that is greater than that of the standard atmosphere at sea level (1,013 millibars). Hyperbaric oxygenation is a procedure in which the patient is exposed to high-pressure oxygen. The technique is used for the treatment of people suffering from carbon monoxide poisoning, compressed-air illness, gas gangrene and serious breathing disorders. Occasionally it is used for patients undergoing cardiac surgery.
Having an increased pressure or density when compared with a standard gas or liquid. Hyperbaric oxygen, e.g., has a greater oxygen concentration than air at sea level, and hyperbaric anesthetics have a greater concentration of dextrose than does the cerebrospinal fluid.
