US Navy hyperbaric oxygenation treatment Table 6 (USN TT6, “standard of care”, which is also used to treat acute carbon monoxide intoxications; many variants exist). One bar absolute pressure is the usual ambient pressure and corresponds to a 10 m column sea water pressure, i.e., at the surface, the absolute pressure is 1 bar and at a 10 m depth, the pressure is 2 bar. One hundred percent oxygen is alternated with short air-breathing periods (time intervals provided in columns) to reduce acute oxygen toxicity at high pressure manifesting in the central nervous system (e.g., convulsions)
