[f. oxi- + -meter.]
A device for measuring the proportion of hæmoglobin in the blood which is in the oxidized form.
1942G. A. Millikan in Rev. Sci. Instruments XIII. 434 (heading) The oximeter, an instrument for measuring continuously the oxygen saturation of arterial blood in man. 1951Anesthesiology XII. 549 With the oximeter it is possible to show how the anesthetist in his manipulations may induce trends which often lead to severe anoxemia. 1966McGraw-Hill Encycl. Sci. & Technol. IX. 469/2 A second type of oximeter is designed to measure the oxygen saturation of blood outside the body during or shortly after withdrawal of the blood from various sites in the vascular system. 1975Sci. Amer. Feb. 69/1 (Advt.), With the ear oximeter, the physician can make the measurement simply by attaching an optoelectronic device to the patient's ear and reading percent oxygen saturation on the display.
Hence oxiˈmetric a., employing an oximeter; oˈximetry, the use of an oximeter.
