This has nothing to do with Oxygen Therapy per se.  If you’re looking for that stuff, please check out the official-ish information on the Oxygen Therapy Wikipedia Page.

Facts about the Definition of the Element Oxygen

A colorless tasteless odourless gaseous element that constitutes 21 percent of the atmosphere and is found in water, in most rocks and minerals, and in numerous organic compounds, that is capable of combining with all elements except the inert gases, that is active in physiological processes, and that is involved especially in combustion processes. The most common uses of Oxygen are in Oxidizer, Rocket propulsion, Medicine, Welding, Sensors, Mask and Concentrators.

What are the origins of the word Oxygen?

The name originates from the Greek words gennan meaning ‘generate’ and oxus meaning ‘acid’ – so named because it was believed that all acids contained oxygen.

Dumb Oxygen Joke:

Q: Why was the mole of oxygen molecules excited when he walked out of the singles bar?
A: He got Avogadro’s number!

Learning about the basic oxygen process:

The basic oxygen process is a steel-making method in which pure oxygen is blown into a bath of molten blast-furnace iron and scrap. The oxygen initiates a series of intensively exothermic (heat-releasing) reactions, including the oxidation of such impurities as carbon, silicon, phosphorus, and manganese.

A typical top-blown basic oxygen furnace is a vertical cylindrical vessel with a closed bottom and an open upper cone through which a water-cooled oxygen lance can be raised and lowered. The vessel is lined with a refractory such as magnetite and is mounted on trunnions so that it can be tilted for charging and also for tapping liquid steel. A charge typically consisting of 70–75 percent molten blast-furnace iron (containing approximately 4 percent carbon), 25–30 percent scrap metal, and lime and other fluxes is fed into the furnace. The lance is lowered into the vessel, and oxygen is injected into the bath at supersonic velocities with flow rates that can exceed 800 cubic m (28,000 cubic feet) per minute. The duration of the oxygen “blow,” normally close to 20 minutes, is varied to reduce the carbon in the steel to the required level. The steel is then tapped into a ladle at temperatures close to 1,600° C (2,900° F), and appropriate ferroalloys and deoxidizers are added to meet the required steel composition. “Heats” of steel, ranging in size from 30 to 360 tons, can be produced in 30 to 45 minutes.
