"Oxygen was discovered by Joseph Priestley (1733–1804) 9 and Carl Wilhelm Scheele (1742-1786) in 1774 1,8. However it was not until 1786 that the word oxygen was coined by the French chemists Morveau and Lavoisier 4."
"Of course, oxygen is vital for the treatment of hypoxic states, however pure 100% oxygen is potentially toxic. The development of a hyperoxic state as may occur when administering high flow oxygen gas to an unwell patient can lead to the formation of reactive oxygen species (ROS), primarily the superoxide anion (O2-●), hydrogen peroxide (H2O2), and the hydroxyl radical (HO●). The hydroxyl radical has the severest injurious effects in the body. These radicals can overwhelm the human body's innate defences and lead to deleterious effects 3."
