any of a number of techniques which are used to measure the metabolic rate of living organisms, usually by monitoring the heat generated by their production of carbon dioxide and nitrogen waste
respirometry in American English
(ˌrespəˈrɑmɪtri)
noun
the branch of medical science dealing with the measurement and analysis of respiration
Word origin
[1930–35; respire + -o- + -metry]This word is first recorded in the period 1930–35. Other words that entered Englishat around the same time include: DNA, acoustic phonetics, boondoggle, uncertainty principle, video-o- is the typical ending of the first element of compounds of Greek origin (as -i- is, in compounds of Latin origin), used regularly in forming new compounds with elementsof Greek origin and often used in English as a connective irrespective of etymology(Franco-Italian; geography; seriocomic; speedometer); -metry is a combining form with the meaning “the process of measuring” that specified bythe initial element. Other words that use the affix -metry include: allometry, dolorimetry, optometry, thermometry, trigonometry
