English[edit]

WOTD – 12 December 2019

Etymology[edit]

A pulse oximeter (sense 2), consisting of a sensor on the finger attached to a device that displays information such as the level of oxygen in the blood and the pulse rate

From oxi- (variant of oxy-) +‎ -meter.[1] The word was first applied in sense 2 (“a device that measures the oxygen saturation of arterial blood”) by American physiologist Glenn Allan Millikan (1906–1947).[2]

Pronunciation[edit]

Noun[edit]

oximeter (plural oximeters)

  1. (chemistry) A device that measures the quantity of oxygen in something, particularly air in the atmosphere.
    Synonym: eudiometer

In Two Volumes, […], volume I, Philadelphia, Pa.: Published by Kimber & Conrad, […], →OCLC, section III (Eudiometry, or Methods of Ascertaining the Purity of Atmospheric Air), page 262:
      The instruments in which the oxigen gas of a determined quantity of air was ascertained, received the name of EUDIOMETERS, because they were considered as measurers of the purity of air. They are however more properly called OXIMETERS.

Brunner, Prof. of Chemistry at Berne. […]”, in Prof. Griscom, transl., edited by Benjamin Silliman, The American Journal of Science and Arts, volume XXIII, number 2, New Haven, Conn.: Published and sold by Hezekiah Howe and A. H. Maltby;  […], footnote, page 286:
      Is it not to be regretted that the term eudiometry and eudiometer should be applied exclusively to the art of determining the quantity of oxygen in the air and the instruments for that purpose? Would not the terms oximetry and oximeter be more appropriate?—Tr[anslator].]
    • 1836, “EUDIO′METER”, in A Medical Vocabulary, or Explanation of All Names, Synonymes, Terms and Phrases Used in Medicine, Surgery, and the Relative Branches of Medical Science; […], Edinburgh: John Carfrae & Son; London: Longman, Rees, Orme, & Co.; Dublin: Hodges & Smith, →OCLC, page 64, column 2:
      EUDIO′METER. [...] An instrument by which the quantity of oxygen and nitrogen in atmospheric air is ascertained: an oxymeter.

      Recalibration of the oxymeters was done in January 1969 with a standard solution. Oxygen recordings by the oxymeters were as low as 10 ppb and agreed well with the Winkler tests. The Magna oxymeter was used successfully throughout the operation period to monitor the oxygen level in the deaerated brine.

      The Chorella experiment studied the growth of algae cultures in a nutrient medium, and an oxymeter was used to study the concentrations of oxygen in human tissue in weightlessness.
  2. (medicine, specifically) A device that measures the oxygen saturation of arterial blood. [from 1942][2]

      The Millikan oxymeter, with which Dr. Howard Bierman has been working and which he has discussed with this group, can be attached to the external ear and gives prompt information about oxygen saturation. It is so calibrated that the administration of 97 to 100% oxygen to normal individuals causes an increase of 5 per cent in the oxymeter reading.

      At 8 to 10 G, ear oximeter readings may fall to 75 percent saturation. The lungs, afterward, may show some atelectasis.

      The study was designed to evaluate use of the oxygen-saturation monitor (pulse oximeter) in patients undergoing aesthetic surgical procedures with adjunctive intravenous sedation in an office-based ambulatory surgical facility. The objective use of the pulse oximeter in this type of setting has not been previously reported in the plastic surgical literature.

      Two technological advances, light-emitting diodes (LEDs) and microprocessors, plus the ingenious idea of analyzing the change in light absorption produced by arterial pulsations, resulted in the development of a new generation of oximeters: the pulse oximeter [...]. Now, clinicians are again thinking of oxygenation as a function of the degree of saturation and oxygen content, as the pulse oximeter becomes the preferred monitoring device.
