Etymology: "Hyperoxemia" is a plain technical coinage built from three Greek-derived elements: "hyper-", meaning "over" or "beyond", "ox-", from the same root as "oxygen", and "-emia", from Greek "haima", meaning "blood". Read together, they describe an excess of oxygen in the blood, which is the sense the word carries in medicine. The "ox-" element points to "oxygen" itself, a name coined in the late 18th century from Greek roots meaning "acid-former", reflecting an early belief that oxygen was the essential component of acids. Because the word is a modern scientific construction, it does not appear in ancient Greek, and its parts were assembled in the same way as other clinical terms ending in "-emia", such as "anemia" and "leukemia".
