Etymology: "Oximeters" is the plural of "oximeter," a device whose name pairs "oxi-," from "oxygen," with "-meter," from the Greek "metron," meaning measure. Antoine Lavoisier coined "oxygen" in 1777 from the Greek "oxys," meaning sharp or acid, because he believed the element was essential to forming acids.
